Answer:T
Step by Step explanation
I think the answer would be 4 and the reason why is because
So if you do 8x14=112 is the area. So 112 divided by 40= 2.8. He will need 2.8 pints of paint.
C=300+1200x-100x. Find x if the total cost is 3,000
3,000 = 300 + 1200x -100x
3000 = 300 + 1100x
2700 = 1100x
2700÷1100=x
x=27/11
x = 2 5/11
Round to 3
5a.
18/9 = 12/x
18x = 12(9)...cross multiply
18x = 108
x=108/18
x=6
