It took Fabian 40 minutes to dig 5 post holes. If he continues at this rate, how long will it take him to dig 20 post holes?
1 answer:
Set up a proportion!
40 minutes / 5 holes = m minutes / 20 holes
Cross multiply.
800 = 5m
m = 160.
It will take him 160 minutes to dig 20 post holes.
Good luck Fabian!
Hope this helps

A) 9(x + 4) = 27
9x + 36 = 27
9x = 27 - 36
9x = -9
x = -9 ÷ 9
x = -1
B) x/3 - 5 = 6
x/3 = 6 + 5
x/3 = 11
x = 11 × 3
x = 33
C) 15 + 3 ( x -7 ) = -30
15 + 3x - 21 = -30
3x + 15 - 21 = -30
3x - 6 = -30
3x = -30 + 6
3x = -24
x = -24 ÷ 3
x = -8
.6578 this would be the answer
Answer:
None of these
Step-by-step explanation:
Apex
This would be 5(6)^2 + 6 - 7
= 180 + 6 - 7 = 179
x=-0.8
