Step-by-step explanation:the lines
Me : 4 x + 8 y = 64
My friend: 8 x + 16 y = 128
A ) 4 * 4 + 8 y = 64
16 + 8 y = 64
8 y = 64 - 16
8 y = 48
y = 48 : 8
y = 6 ( me and my friend work 6 hours at the second job )
B ) The number of hours we each work at the first job are also the same.

The equation computed shows that the number of minutes that it will take to process fifteen passengers is 11.11 minutes.
<h3>How to solve the equation</h3>
Since Katrina averages fifteen passengers every twenty minutes and Stefon also works for the airline and averages fifteen passengers every twenty-five minutes, this can be represented this:
1/x = 1/20 + 1/25
1/x = 9/100
9x = 100
Divide through by 9
x = 100/9
x = 11.11 minutes

Step-by-step explanation:
We know that since the rectangular prism has a square base, the length and width are equal
So we have V = 10 * 10 * 15
For the small rectangular slab we can subtract 10 from 40 to get 30 for the length
Thus we have V = 30 * 4 * 7
