Evaluate each expression when s=9 and t=12.

Question

3(3t + s)
A. 9
B. 24
C. 45
D. 135
(I am not asking for the answer I need help so that's why I did not put my answer down)

Answer 1

When substituting values, you take the expression and just replace it with the number you're substituting it for. So 3t becomes 3(12) because t=12, and since s=9, the expression becomes 3[3(12)+9] (using brackets because that's easier). Hope that helps. Let me know if you are still confused.

Answer 2

which do you solve first?

Answer 3

What do you mean? The values of each variable are given to you (meaning t=12 and s=9). You have to substitute them in the expression and evaluate.

Answer 4

Put t = 12 and s = 9 into equations.

1:
3 ( 3 t + s ) = 3 * ( 3 * 12 + 9 ) = 3 * ( 36 + 9 ) = 3 * 45 = 135

Does this help?
