Answer:
w= -4
Step-by-step explanation:
First we know 8 x 4 is 32 so then we make the 8 negative
and divide -8 by 32 which is -4
You can check it by doing -4 x -8 which is 32!
Remember-
1. When you multiply two negatives it equals a positive.
2. You can check by plugging -4 where w is then solving.
3. If there is a subtraction next to a number (w-8) then whichever number the subtraction sign is in front of is negative.
4. If a variable is next to a number it means to multiply the variable by the number.
if -13x-71=201 what is x
Answer:
272/-13 or −20.923
Step-by-step explanation:
To solve this equation you need to isolate the variable.
First, add 71 to both sides
-13x-71+71=201+71
-13x=272
Then, divide both sides by -13
-13x/-13=272/-13
So, x=272/-13 or −20.923
Which of these is a factor of 10?
A. 20
B. 2
C. 4
Answer:
B. 2
Hope this helps!
Step-by-step explanation:
The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

If Lily got 18 questions right on a 20 questions
test, what percentage of the questions did she
get wrong?
Answer:
She got 10% of the questions wrong !
Step-by-step explanation:
To solve this problem I used cross multiplication
[tex]\frac{x}{100}= \frac{18}{20}[/tex]
18 x 100 =1800
1800 / 20 = 90
Since they are asking what she got wrong, not what she got right, you just need to subtract.
100% - 90% = 10%
hope this helped !
Answer:
10%
Step-by-step explanation:
18/20 Questions = 0.9 or 90% she got right
2/20 Questions = 0.1 or 10% she got wrong

Luis has a pyramid shaped plant pot. It has a square base with a side length of 36 cm, and the height of the pot is 36 cm. Luis wants to fill the pot with soil so that the soil takes up 75% of the pot's volume. How far up the pot will the soil reach?
Answer:
The required volume, if he wants to fill 75% of the pot's volume, is 11664cm³
Step-by-step explanation:
The volume of a pyramid is given as
[tex]V = \frac{1}{3} \times A \times h[/tex]
Where V is the pot's volume, A is the base area and h is the height.
Our base is a square, so the base area, if s denotes the side length, would be s x s.
s = 36cm, therefore we have A = 36cm X 36cm = 1296cm².
The height is given as 36cm, therefore we have our volume to be:
[tex]V = \frac{1}{3} \times 1296cm^2 \times 36cm[/tex]
[tex]V = 15552cm^3[/tex]
Since Luis wants to fill 75% of the pot's volume with soil. Then it will take
[tex]\frac{75}{100} \times 15552cm^3 = 11664cm^3 [/tex]
Thus, the required volume, if he wants to fill 75% of the pot's volume, is 11664cm³

9) A model airplane kit has a scale factor of 1/144. If the wingspan of the airplane is 1152 inches long, how long would the wingspan of the model airplane be? (Type just the number without the units)
Given:
Scale factor is [tex]\dfrac{1}{144}[/tex].
Length of wingspan of the airplane = 1152 inches
To find:
The length of wingspan of the model airplane.
Solution:
Scale factor is [tex]\dfrac{1}{144}[/tex]. It means,
1 inches of airplane [tex]=\dfrac{1}{144}[/tex] inches of model airplane.
1152 inches of airplane [tex]=1152\times \dfrac{1}{144}[/tex] inches of model airplane
[tex]=8[/tex] inches of model airplane
Therefore, the length of wingspan of the model airplane is 8 inches.

Answer:
$225 = $15 a + $ 10 c
Given,
Total price = $225
Cost of concert ticket for adults= $15
Cost of concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Now,
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c

Reciprocal is reversing the given fraction.
1. Would be 8/3
2. 2 2/3 as in improper fraction is 8/3, reciprocal would be 3/8

A stock loses $1.50 each day over a five-day period. What is the total change in the value of the stock at the end of five days? (remember to have two numbers after the decimal)
Given:
A stock loses $1.50 each day over a five-day period.
To find:
The total change in the value of the stock at the end of five days.
Solution:
Stock loses each day = $1.50
We know that, loss or reduction represented as negative change.
So, change in the value of the stock per day = -$1.50
Change in the value of the stock in 5 days = 5×(-$1.50)
= -$7.50
Therefore, the change in the value of the stock at the end of five days is -$7.50. It means, the value of the stock loses $7.50 at the end of five days.
