?
Step-by-step explanation:
Your numbers would be 6 and -1
Answer:
D
Step-by-step explanation:
Call the first person A who can do the job in 5 hours.
Call the second person B who can do the job in 7 hours.
The formula for this problem is
Time = A*B/(A + B)
Time = 5*7 / (5 + 7)
Time = 35 / 12
Time = 2 hours and 11/12 of an hour.
The answer is D.
Answer:
(-2x+4)+2(2x+1) = 2x+6
2(3x+5)-4(x-1) = 2x+6
2(x-7)+(8x+20) = 10x+6
They should be the answers if the simplified forms can be used twice.
