Question

Evaluate: 2m + 5n, when m = -13 and n = 10.
A. 24
B. -24
C. 4
D. -4

Answer 1

A. 24

Answer 2

The answer would be A but you need to know how to do this soo , you simply plug in the values for M and N , so that means the equation would be like this now ; 2*(-13)+5*10. Then Simplify 2*(-13)+5*10 which would be -26+50 , simplify that and you get 24.

Answer 3

2(-13=-26 5(10)=50 -26+50=24

Answer 4

slightly confused but i understand thank you both

Answer 5

substitute the -13 in for m then substitute the 10 in for n then multiply -13*2 and 10*5 and then add them together
