Question

What is the value of t? 3.5(t+6)=7 A. -4 B. -0.25 C. 0.25 D. 4

Answer 1

3.5t+21=7     Distribute the 3.5 in the parenthesis
3.5t= -14       Subtract 21 from both sides
t= -4              Divide 3.5 from both sides.

Answer 2

A because when you distribute you get 3.5t + 21 = 7. Then subtract 21 from both sides to get 3.5t = -14. Then divide both sides by 3.5t to get -4.
