So first you multiply 2 and 4x to get 8x. Then you multiply 2 and 5 to get 10. So the problem will look like:
8x+10=90
Then you subtract 10 on both sides of the problem to get:
8x=80
And then divide 8 on both sides to get
x=10

Your answer is about 12.48
Step-by-step explanation:
h = 3(V/pi*r²)
h = 3(640.23/pi*7²)
h = 3(640.23/153.93804)
h = 3(4.157516881)
h = 12.47703

It takes 70 minutes for 9 team members (painting 60 sq ft per minute) to paint a 4200 sq ft wall.
Step-by-step explanation:
4800 ÷ 20 = 240 sq ft per team member in 36 minutes
240 ÷ 36 = 6.67 sq ft per team member in 1 minute
6.67 × 9 = 60 sq ft per 9 team members in 1 minute
4200 ÷ 60 = 70 minutes (or 1 hour and 10 minutes)
