Answer:
w = -8
Step-by-step explanation:
Distribute: -6 = 2w + 10
Remove the 10: -6 -10 = 2w +10 -10 ---> -16 = 2w
Isolate the variable: -16/2 = 2w/2
Answer: -8 = w
Mr. Boon went to the fair and bought 2 churros (x) and 3 sodas(y) for a total of $12.
The equation 2x + 3y = 12 demonstrates the situation.
If the sodas cost $2 each, how much do the churros cost? (Don't forget the units)
Answer:
$3
Step-by-step explanation:
Plug in 2 for y, so you get 2x + 3(2) = 12, and that simplified would be
2x + 6 = 12. Next, subtract 6 from both sides, so you get 2x = 6. Divide 2 by both sides to get 3!
Write the equation of a line that is perpendicular to y=2/7x +9 and that passes through the point (4,-6).
Answer:
[tex]y=-\frac{7}{2}x+8[/tex]
Step-by-step explanation:
Given the equation
[tex]y\:=\:\frac{2}{7}x+9[/tex]
comparing the equation with the slope-intercept form
[tex]y =mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is 2/7
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -7/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-6\right)=\frac{-7}{2}\left(x-4\right)[/tex]
[tex]y+6=\frac{-7}{2}\left(x-4\right)[/tex]
[tex]y+6-6=\frac{-7}{2}\left(x-4\right)-6[/tex]
[tex]y=-\frac{7}{2}x+8[/tex]

A pair of jeans are originally priced at $30.00 jeans go on sale for 20% off, what is the difference between the sale price and the original cost?
Answer:
$ 6
Step-by-step explanation:
Discount = 20% of 30
[tex]= \frac{20}{100}*30[/tex]
= 2 * 3
= $ 6
Difference between the sale price and the original cost = $ 6
You need to buy 12 tickets to a weekend concert festival but have two options for where to purchase them. Concert Specialties sells a pack of 3 tickets for $75 and We 'R' Entertainment sells a pack of 4 tickets for $108. Which ticket outlet should you buy the 12 tickets from to spend the least amount of money? Explain your reasoning.
Answer:
Concert Specialties is the better buy
Step-by-step explanation:
In order to determine which of the two deals is the better buy, we first need to find out how many of each pack we would need to get the needed 12 tickets. Once we have this value we multiply it by the dollar amount of each pack and compare the totals like so...
Concert Specialties => pack of 3 * 4 = 12 tickets => 4 * 75 = $300
We 'R' Entertainment => pack of 4 * 3 = 12 tickets => 3 * 108 = $324
Therefore, we can now see that the Concert Specialties is the better buy since you are getting the 12 tickets for $24 less than We 'R' Entertainment

What is the measure of angle 1?
A. 90
B. 45
C. Not enough info
D. 180
Answer:
C ig.
Step-by-step explanation:
well, it's not a right angle (90 degrees), it's not a 45 degree angle, and it's not a straight angle (180 degrees), so it's not enough info
Answer: C not enough info
Step-by-step explanation: if it was 90 it would have a box instead of a circle. 45 would be more obvious and 180 is a straight line. In order to find <1 you need to know the angle next to it. So it does not work. Hope this helped. go answer my question!
Chad sells 3 pounds of barbecue for $28.74. If
the cost of the barbecue varies directly with the
number of pounds sold, which of the following

Answer:
7.5 gallons
Step-by-step explanation:
divide 12 by 3 to get oz per minute. 4
do 60 × 4 to get total minutes 240
4×240=960
put 960 oz into gallons and get 7.5
Translate five times the sum of a number and three into a mathematical expression
Answer:
5(x-3)
Step-by-step explanation:
The word "SUM" means the answer to an "ADDITION".
"SUM" is always used with the word "AND" to indicate which numbers are being added.
The SUM of a number AND -3 is written as:
( x + ( − 3 ) ), or ( x -3 )
(where we have chosen the number to be x .)
But we want FIVE of those sums; this means:
5 ( x − 3 )
f (x) = 2x + 4
Solve for x when f (x) = 17

Step-by-step explanation:
If you multiply 2 by 3 it'll equal to 6. Same with 7 x 3= 21.
You could also subtract 7 from 2 equalling 5 and 21 - 6 equal to 15. Then you would but y over x giving you 15/5. 15 divided by 5 is 3. So both ways you get 3.

Ross is shopping for mulch that costs $1.29 per cubic foot. During his first trip to the store, he bought 16.5 cubic feet. He needs another 4.5 cubic feet to complete his landscaping project.
Answer:
$27.09 in all
Step-by-step explanation:
$1.29 × 16.5 = $21.285
$1.29 × 4.5 = $5.805
$21.285 + $5.805 = $27.09

A store manager wants to mix two different brands of coffee to make 480 pounds to sell at $2.68 a pound. He uses a brand of coffee worth $2.50 a pound and another brand worth $2.80 a pound. How many pounds of each should be used?
Answer:
Let's define:
X = number of pounds of the brand 1 (price = $2.50 per pound)
Y = number of pounds of the brand 2 (price = $2.80 per pound)
We want to make a mix of 480 pounds, then:
X + Y = 480.
And we want the mean price to be $2.68, then:
(X*$2.50 + Y*$2.80)/480 = $2.68
Then we have a system of equations:
X + Y = 480
(X*$2.50 + Y*$2.80)/480 = $2.68
To solve this, the first step will be to isolate one variable in one of the equations, and then replace this in the other equation.
Let's isolate X in the first eq.
X = 480 - Y.
Now we can replace this in the other equation and get:
((480 - Y)*$2.50 + Y*$2.80)/480 = $2.68
Now let's solve this for Y.
((480 - Y)*$2.50 + Y*$2.80) = $2.68*480 = $1,286.40
$1,200 + Y*$0.30 = $1,286.40
y*$0.30 = $1,286.40 - $1,200 = $86.40
Y = $86.40/$0.30 = 288
Then:
X = 480 - Y = 480 - 288 = 192
Then the manager must use 192 pounds of the brand that costs $2.50 per pound, and 288 pounds of the brand that costs $2.80 per pound.
