Will give brainliest -2u+6w=9 rearrange the equation so w is an independent variable. PLEASE HELP!
Answer:
[tex]\Large \boxed{w=\frac{2u+9}{6} }[/tex]
Step-by-step explanation:
[tex]-2u+6w=9[/tex]
Adding 2u to both sides.
[tex]6w=9+2u[/tex]
Dividing both sides by 6.
[tex]\displaystyle w=\frac{2u+9}{6}[/tex]
Answer:
So we have this equation:
[tex]-2u + 6w = 9[/tex]
And we need to rearrange it to make the w an independent variable.
That means we need to solve the equation for w:
[tex]-2u + 6w = 9[/tex]
First thing we need to do is passing the [tex]-2u[/tex] to the right summing:
[tex]6w = 9 + 2u[/tex]
Next, we can pass the 6 (which is multiplying the w) to the right dividing:
[tex]w = \frac{9+2u}{6}[/tex]
we can also write it as this:
[tex]w = \frac{9}{6}+\frac{2u}{6}=\frac{3}{2}+\frac{u}{3}[/tex]

Each play can score up to 10 points in each round of the game. Elena and four of her friends divided to form a team and play a round. Write an expression, an equation, or an inequality for each quantity described here. If you use a variable, specify what it represents
Answer:
The inequality for each quantity described is given as follows;
0 ≤ A + B + C + D + E ≤ 50
Step-by-step explanation:
The given information are;
The number of players each team can have = between 3 and 5
The maximum number of points a player can score in each round of the game = 10 points
The number of players in Elena's team = Elena + 4 = 5 players
The total number of points Elena's team earns at the end of the round is given as follows;
0 ≤ A + B + C + D + E ≤ 5 × 10
Where the variables A, B, C, D, and E are the points each of Elena and are makes such that the minimum points is 0 + 0 + 0 + 0 + 0 = 0 and the maximum point is 10 + 10 + 10 + 10 + 10 = 5 × 10 = 50, which gives;
0 ≤ A + B + C + D + E ≤ 50.

A cabinet is 6 feet high, 3 feet wide and 2 feet long. The entire outside of the cabinet is being painted, except for the bottom. What is the surface area being painted?
Answer:
66ft²Step-by-step explanation:
The cabinet is rectangular shaped. Using the formula for calculating the surface area of a reactangular bos to solve the problem.
Surface area = 2(LW+WH+LH) where;
L is the length of the cabinet
W is the width of the cabinet
H is the height of the cabinet.
If the entire outside of the cabinet is being painted, except for the bottom, then the surface area of the painted area will be expressed as;
S = LW+2WH+2LH
Given L = 2 feet, W = 3 feet and H = 6 feet
S = 2(3)+2(3*6)+2(2*6)
S = 6+2(18)+2(12)
S = 6+36+24
S = 66 feet²
Hence the surface area of the painted part is 66ft²

Computer cost 90% of the price of the HP computer if the university spent a total 1650000 what is the cost of each IBM computer
Complete question :
The University but a total of 2200 computers they bought three kinds of computers HP, IBM and dell. The ratio of theNumber of HP computers to IBM to dell is 2:3:6 each HP computer cost $750 each dell computer cost 90% of the price of an HP computer if the University spent a total of $1,650,000 what is the total cost of each IBM computer
Answer:
$900
Step-by-step explanation:
Given that :
Total amount of computers purchased = 2200
Number of brands purchased = 3;
HP, IBM and DELL
The ratio of theNumber of HP computers to IBM to dell is 2:3:6
Cost per HP = $750
Cost per Dell = 90% of HP = 0.9 × $750 = $675
Total amount spent = $1,650,000
2:3:6 = (2+3+6) = 11
Number of IBM computers purchased :
(3/11) * 2200 = 600 IBM
(2/11) * 2200 = 400 HP
(6/11) * 2200 = 1200 DELL
TOTAL Cost of HP = (400 × $750) = $300,000
TOTAL cost of Dell = (1200 * $675) = $810,000
TOTAL cost of IBM :
$1,650,000 - ($300,000 + $810,000)
$1,650,000 - $1,110,000 = $540,000
Cost of each IBM:
540,000 / 600 = $900

1. Triangle ABC with coordinate points A(-2,3); B(-1,0); C(5,-4) is rotated 90 degrees clockwise. What
are the new image points for triangle A'B'C'?
Answer: A'(3,2), B'(0,1) and C'(-4, -5).
Step-by-step explanation:
When we rotate (a,b) 90 degrees clockwise, the new point will be (b,-a).
i.e. rotation rule for 90 degrees clockwise : (x,y) → (y,-x)
Given: Triangle ABC with coordinate points A(-2,3); B(-1,0); C(5,-4) is rotated 90 degrees clockwise.
Then, the new image points for triangle A'B'C' will be :
A(-2,3) → A'(3,-(-2)) =A'(3,2)
B(-1,0)→ B'(0,-(-1)) = B'(0,1)
C(5,-4) → C'(-4, -5)
Hence, the new image points for triangle A'B'C' are A'(3,2), B'(0,1) and C'(-4, -5).

In 2010 Sacramento received 23 inches in annual precipitation , in 2011 the city received 17 inches in anual percpation , in which year was there more precpition?
Answer:
There was more precipitation in the year 2010.
Step-by-step explanation:
Here in this question, we have the data for the amount of precipitation received in two different years in a city called Sacramento.
Now, we are tasked with finding in which of the two years was there more precipitation.
From the question, we can identify the following;
in 2010, precipitation was 23 inches
in 2011, precipitation was 17 inches
We can see that 23 inches is greater than 17 inches. So what this mean is that the precipitation in 2010 was more than the precipitation received in 2011.
Every negative integer J is less than or equal to its inverse
Answer:
Here we have the statement:
" Every negative integer J is less than or equal to its inverse"
First, remember that when we are talking about negative numbers, the ones that are closer to 0 are the larger ones.
For example, if we have -1 and -5
-1 is closer to zero, then:
-1 > -5
Now we have a negative integer J.
The smallest negative integer is -1
it's inverse is 1/-1 = -1
Then, if j = -1:
j = 1/j
-1 = 1/-1 = -1
and if j < -1 (-2, -3, -4, -5.......)
then for example, for j = -2
1/-2 = - (1/2)
and (-1/2) is a number between -1 and 0
So it is closer to zero than -2
then:
(-1/2) > -2.
Then, concludin, if IjI > 1, we have always that 0 > 1/j > -1 > j.

Rebecca Wilson was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 846 points. The number of two-point field goals that Rebecca made was 77 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 30 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Rebecca Wilson made during the 2006 regular season.
Answer:
Number of two point goals = 169
Number of three point goals = 123
Number of free throws = 139
Step-by-step explanation:
Let the number of two point goals = [tex]x[/tex]
Let the number of three point goals = [tex]y[/tex]
Let the number of free throws = [tex]z[/tex]
As per the given statements:
[tex]x = 2y-77 ...... (1)[/tex]
[tex]z = x-30 ...... (2)[/tex]
Using equation (1):
[tex]z = 2y-107[/tex] ...... (3)
Total number of points from two point goals = [tex]2x[/tex]
Total number of points from three point goals = [tex]3y[/tex]
Total number of points from free throws = [tex]z[/tex]
[tex]2x+3y+z=846[/tex]
using (1) and (3):
[tex]2(2y-77)+3y+2y-107=846\\\Rightarrow 4y-154+5y-107=846\\\Rightarrow 9y-261=846\\\Rightarrow 9y=846+261\\\Rightarrow 9y=1107\\\Rightarrow y =123[/tex]
By (1):
[tex]x = 2\times 123-77 =169[/tex]
By (3):
[tex]z =2\times 123-107 = 139[/tex]
So, answers are:
Number of two point goals = 169
Number of three point goals = 123
Number of free throws = 139

Show your work. Part B: How much money does Sue save each month with the change in cereal brand if she buys 4 cereal boxes each month? Show your work. (10 points) PLEASEEEEEE help
Answer:
part A : $4
part B : $16
Sue buys a certain brand of cereal that costs = $12 per box.
She changes to a super-saving brand of the same size.
The equation showing price y as a function of the number of boxes, x is for the new brand.
y = 8x
for x = 1, y = 8
So for 1 box super-saver cereal brand costs $8.00
Part A. - So saving per box = 12 - 8 = $4
Part B. - Money saved in 1 box = $4
Therefore, money saved in 4 boxes = 4 × 4 = $16
HOPE THIS HELP YOU FRIEND
The price of the Sue's original box is $4 more than the super saving brand's box. Sue saves $16 per month if she buys 4 cereal boxes each month.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, we're specified that:
Price of original cereal box = $12 per box.Price of super saving box = y = 8x, where x is the number of boxes.putting x= 1, we get y = 8. Thus, for each box of super saving brand, Sue pays $8.
The difference between both box's price is: 12 - 8 = 4 dollars.
Also, as Sue saves 4 dollars on each box of cereal, and she buys 4 boxes of cereal, then if she buys the boxes of super saving brands, then she saves 4 dollars per box for 4 boxes, whose total is 4 times 4 = 16 dollars.
Thus, the price of the Sue's original box is $4 more than the super saving brand's box. Sue saves $16 per month if she buys 4 cereal boxes each month.

Complete question is;
The function f(x) = (25000 + 280x)/x models the average cost per unit, f(x), for Electrostuff to manufacture x units of Electrogadget IV. How many units must the company produce to have an average cost per unit of $390?
Answer:
227 units
Step-by-step explanation:
We are given the function;
f(x) = (25000 + 280x)/x
Where;
f(x) is the average cost per unit
x is the number of units
Now, we want to find out how many units the company must produce to have an average cost per unit of $390.
Thus, plugging $390 for f(x), we have;
390 = (25000 + 280x)/x
When we cross multiply, we get;
390x = 25000 + 280x
390x - 280x = 25000
110x = 25000
x = 25000/110
