Answer:
7(2x+16)
Step-by-step explanation:
first, we look at the part where it says the sum of twice a number and 16
let's represent the number by using x. since it says twice a number, that would mean 2x.
when it says the sum of twice a number and 16, this means that we have to add them, so we would get 2x+16.
finally, in the beginning it says seven times the sum of twice a number and x, which would mean that we would have to multiple 2x+16 by 7.
answer:
x * x = x^2
x * .7 = .7x
-6 * x = -6x
-6 * .7 = -4.2
x^2 + .7x - 6x -4.2
x^2 - 5.3 - 4.2
x = 6
100C=m
If 250 copies are made in 2.5 minutes, you get the equation:
250c=2.5m
divide by 2.5 on both sides and you get:
100c=m
So in m minutes, 100c copies are made.
The answer is Pedro.
