Joe completes an average of (10 ft)/(5 h) = 2 ft/hour. Bill completes an average of (10 ft)/(4 h) = 2.5 ft/hour. Together, they complete 2+2.5 = 4.5 ft/hour. At that rate, it will take them
... (120 ft)/(4.5 ft/h) = 26 2/3 h
7x + 1 = 2(2x - 1) + 3(x + 1)
7x + 1 = 4x - 2 + 3x + 3
7x + 1 = 7x + 1

Answer:
x - 5
Step-by-step explanation:
1) Given binomials:
First binomial 7r - 5
Second binomial 5r + 8
2) To pass from 7r to 5r you have to subtract 2r, so the first term of the binomial to be subtracted is 2r
3) To pass form - 5 to + 8, you have fo subtract - 13
4) So the answer is 2r - 13, option b.
Answer:
D. -15
Step-by-step explanation:
f(x)=7
f(x) = -3x + 6
Then substitute x for 7 and solve linearly.
-3(7)+6
-21+6
=-15
The answer is D
