The answers from questions 6 to 9 are A, C, D, and C.
Answer:
t = -1
Step-by-step explanation:
15(t+2)+9t=6
15t + 30 + 9t = 6
combine like terms
24t +30 = 6
subtract 30 both sides
24t = -24
t = -1
22-5(6v-1) = -63
22- 30v + 5 = -63
27 -30v = -63
subtract both sides by 27
-30v = -90
divide it by -30
v = 3
