Answer:
7w-14
7(9)-14
63-14
49
Step-by-step explanation:
Answer:
49
Step-by-step explanation:
since the value of W is given, 9, we have to plug it into the expression to simplify it further.
9 x 7 = 63
63 - 14 = 59

Solve the equation -2x + 9 - 3x= -5x + 3
Answer:
There are no solutions
Step-by-step explanation:
Answer:
no real solutions
Step-by-step explanation:
-2x + 9 - 3x = -5x + 3
First, combine like terms on each side.
-2x - 3x + 9 = -5x + 3
-5x + 9 = -5x + 3
Continue to combine the like terms from both sides.
0 = -6
The above expression is not true, therefore, there are no real solutions.
Please any help is greatly appreciated

Neelam's daily income is ₹ 800. Her daily savings amount is ₹100. What is the ratio of her SAVINGS to her EXPENDITURE? a. 1 : 2 b. 1 : 7 c. 1 : 6 d. 1 : 5
Given:
Neelam's daily income is ₹800.
Her daily savings amount is ₹100.
To find:
The ratio of her SAVINGS to her EXPENDITURE.
Solution:
We have,
Income = ₹800
Saving = ₹100
Expenditure = Income - Saving
= ₹800 - ₹100
= ₹700
We need to find the ratio of her SAVINGS to her EXPENDITURE.
[tex]Ratio=\dfrac{Savings}{Expenditure}[/tex]
[tex]Ratio=\dfrac{100}{700}[/tex]
[tex]Ratio=\dfrac{1}{7}[/tex]
[tex]Ratio=1:7[/tex]
Therefore, the correct option is b.

2a+b=5 and 6y+4y=48 show that 20a+10b has a greater value than 3x+2y
Answer:
Step-by-step explanation:
There is an error in the question. 6x+4y = 48
Multiply first equation by 10:
20x+10y = 50
Divide second equation by 2:
3x+2y = 24
50>24, so 20x+10y > 3x+2y
GEOMETRY Holly can make an open-topped box out of a square piece of cardboard by cutting 3-inch squares from the corners and folding up the sides to meet. The volume of the resulting box is V = 3x^ 2 – 36x + 108, where x is the original length and width of the cardboard.
Factor the polynomial expression from the volume equation.
HINT: look for a GCF first!
Answer:
[tex]V(x)=3(x-6)(x-6)[/tex]
Step-by-step explanation:
Polynomial Factoring
The volume of a cardboard box is expressed as:
[tex]V(x)=3x^2-36x+108[/tex]
It's required to factor that expression.
First, factor out 3:
[tex]V(x)=3(x^2-12x+36)[/tex]
The expression in parentheses is a perfect square:
[tex]\boxed{V(x)=3(x-6)(x-6)}[/tex]

Jaimie is practicing for the long jump. Each week she makes 10 jumps and after each jump she records the distance, in meters, she reaches with each jump. Her results for this week are represented in the table below. Jump 1 2 3 4 5 6 7 8 9 10 Distance (m) 5.1 5.3 5.4 5.2 5.5 5.4 5.2 5.3 5.5 3.5 Jaimie then reviews her results and determines the mean and standard deviation so that she can compare her results from this week to her results from the previous week. Jaimie felt the 10th jump was not reflective of her ability because she stumbled before making the jump and decided to remove the 10th jump from her data set. Determine whether each statement describes the change that will occur to the mean and standard deviation from this week's results when Jaimie removes the 10th jump from her data set. Select Yes or No for each statement. Yes No Removing the 10th jump from her data set will cause her average jump distance to increase. Removing the 10th jump from her data set will cause her average jump distance to decrease. The standard deviation will increase because the jump distances will be more spread out. The standard deviation will decrease because the jump distances will be more clustered together.
Answer:
mean=(5.1 +5.3+ 5.4 +5.2+ 5.5 +5.4+ 5.2 +5.3 +5.5+ 3.5)/10=51.4/10=5.14

Answer:
brown = 12
yellow = 30
orange = 36
Step-by-step explanation:
let 'b' = # brown
let '18+b' = # yellow
let '3b' = #orange
add them together and set equal to 78
b + 18 + b + 3b = 78
5b + 18 = 78
5b = 60
b = 12
y = 12 + 18 = 30
o = 3(12) = 36
12 + 30 + 36 = 78

If 8x - 5y = -8 is a true equation, what would be the value of -5y + 8x?
Answer:
Answer:
The value of -5y + 8x would be 8.
Step-by-step explanation:
The new equation is just the original equation but multiplied by -1 to make the symbols different. By following this rule, -8 would turn into just 8.
lf p+q/s=9, q/p =4, and square q=6, what is the value of s?
Answer:
s=5
Step-by-step explanation:
The third equation implies that q=36.
Substitute for q in the second equation to get
36/p=4
Now solve for p
p/36=1/4
p=36/4=9
Solve the first equation for s.
s/(p+q)=1/9
s=(p+q)/9
Now substitute for q and p in this equation.
s=(9+36)/9=45/9=5

Using the slope formula, find the slope of the line through the points (0,0) and (4,8) . Use pencil and paper. Explain how you can use mental math to find the slope of the line
Answer:
Look below! I hope this helps, and mark as brainliest please!
Step-by-step explanation:
The formula for slope is (y2-y1) divided by (x2-x1). So in this case, we have (8-0) divided by (4-0) so we get 8 over 4 and that is 2. So the slope is 2.
if f(x)= 3x-4, find f(-2) - f(3)
Answer:
-15
