Answer:
P / 30 - 21= 9
2w = 9
w = 4.5
This should be the answer
A - 2 1/2 = 1 1/2
Solve for A by adding 2 1/2 to both sides:
A = 1 1/2 + 2 1/2
A = 4
The answer is c. A = 4
Check: 4 - 2 1/2 = 1 1/2
The volume of a rectangular prism is given by the multiplication of its three dimensions: if
are the width, height and length of the prism, the volume is
![V = w\cdot h\cdot l](https://tex.z-dn.net/?f=%20V%20%3D%20w%5Ccdot%20h%5Ccdot%20l%20)
So, in your case, you have
![V = \dfrac{3}{8} \cdot \dfrac{5}{8} \cdot \dfrac{7}{8} = \dfrac{3\cdot 5 \cdot 7}{8\cdot 8 \cdot 8} = \dfrac{105}{512}](https://tex.z-dn.net/?f=%20V%20%3D%20%5Cdfrac%7B3%7D%7B8%7D%20%5Ccdot%20%5Cdfrac%7B5%7D%7B8%7D%20%5Ccdot%20%5Cdfrac%7B7%7D%7B8%7D%20%3D%20%5Cdfrac%7B3%5Ccdot%205%20%5Ccdot%207%7D%7B8%5Ccdot%208%20%5Ccdot%208%7D%20%3D%20%5Cdfrac%7B105%7D%7B512%7D)
Answer: 6
Step-by-step explanation:
2×2=4
4+2=6
6x+3y=15
6*2+3y=15
12+3y=15
3y=3
y=1
6x+3y=15
6*5+3y=15
30+3y=15
3y=-15
y=-5
The answers is y=1 & -5
