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
