Help, Missing work!!!
Answer:
Step-by-step explanation:
11) add 20 to both sides, x=-3
12) divide both sides by -8, v=18
13) divide both sides by -7, n=19
14) multiply both sides by 9, n=171
Answer:
11. x= -3
12. v=8
13. n=19
14. n=171
Step-by-step explanation:
11. 20+3=23, but since the answer is negative, the 3 has to be negative (different signs = negative)
12. 144/8 = 8, since product is negative, the answer has to be positive (different signs = negative)
13. 133/7= 19, answer must be positive because product is negative (different signs= negative)
14. 9*19=171, so therefore 171/9=19

Answer:
10000
Step-by-step explanation:
5000+100(50)
=10000
Answer:
My Answer
Step-by-step explanation:
[tex]\frac{5000}{100}[/tex] × [tex]\frac{x}{50}[/tex]
5000x50 = 100xX
250000 = 100X
[tex]\frac{250000}{100}[/tex] = [tex]\frac{100x}{100}[/tex]
2500 = x
Not completely sure if this is right, but I hope it helps!

Answer:
8000 in³ because 20 × 20 × 20 is 8000
Answer and Step-by-step explanation:
We are given:
Each side of the box is 20 inches.
A side of the box is denoted as s.
The volume of a cube is [tex]V=s^{3}[/tex]
If s is a side of the box, and one side of the box is 20 in., then that means s is equal to 20.
So, to find the volume, we plug 20 in for s in the volume equation.
[tex]V = 20^{3}[/tex]
(This is the same as saying 20 times 20 times 20).
V = 8,000 [tex]in^{3}[/tex]
