Solution
Part 3
For this case we have 6 different terms
Part 4
We can do the following:

Part 5
And we can simplify on this way:

Answer:
35% of 90x = 31.5
16x is 9x =
Step-by-step explanation:
35 /100 x 90 = 31.5
Step-by-step explanation:
V = 1/2 a x c x h
1/2 * 7*12*18 = 756 yd ^3
31,680 feet per hour.
There are 5280 feet in a mile, so 6(5280)=31,680
I believe it's 6/12, but simplified to the lowest form is 1/2
