Your answer is 77/60 or 1 17/60
0.12 x 70 = 8.4
12% of 70 is 8.4
Answer:
Step-by-step explanation:
If Daniel does 1/9 of the job in one hour
let x = Paul's rate
Paul does 1/x of the job in one hour
They both do the job in 4.95hrs
(1/9)(4.95) + (1/x)(4.95) = job completion
multiply both sides by 9x
(9x)(1/9)(4.95) + (9x)(1/x)(4.95) = 9x(1)
4.95x + 9*4.95 = 9x
4.95x + 44.55 = 9x
9x - 4.95x = 44.55
4.05x = 44.55
x = 44.55/4.05
x = 11 hours i.e time it takes for Paul to pick the 40 bushels alone

Answer:
2x-5
Step-by-step explanation:
f(g(x) means stick g(x) into f(x) in place of x
f(x) = 2x+1
f(g(x) ) = 2(g(x)) +1
and we know that g(x) = x-3
so replace g(x) with x-3
f(g(x) ) = 2(x-3) +1
Distribute
f(g(x)) = 2x-6+1
= 2x-5
