Which equation represents the sentence, "three times the number m plus twice the quantity n plus 5 is equal to 20"? a. 3m + 2n – 5 = 20 b. 3m + 2(n + 5) = 20 c. 3m + 2(n – 5) = 20 d. 3m(2n + 5) = 20

 B, 3m + 2(n + 5) = 20. (I've done the test)

A, C, and D aren't it because it says 3 times the number m (3m) plus n plus 5 to the second power 2(n + 5), equals 20, and B is the only one that represents the equation.  

answer: just subtact the units and then add the non negative : happy to

step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.
