Answer:

B) - 53 + 4k = 7

Step-by-step explanation:


Substitute k=15 into each equation

A) 3k - 11 = -34  

3(15) -11 = -34

45 -11=-34

34 = -34

not true

B) - 53 + 4k = 7

-53 +4(15) =7

-53 +60=7

7 =7

true

C) k/3 + 17 = 12

15/3 +17 =12

5+17 =12

22 =12

False

D) k/5 + 2.5 = 0.5

15/5+2.5 =.5

3 +2.5 =.5

5.5 =.5

False
