Variable Equations Evaluation
To solve this question, we need to plug in the given value for the variable into each equation and determine if the equation holds true.
A. n + 7 = 16; n = 15
Substitute n = 15 into the equation:
15 + 7 = 22
This is not equal to 16, so the answer is No.
B. 2/3v = 8; v = 12
Substitute v = 12 into the equation:
2/3 * 12 = 8
8 = 8
This is true, so the answer is Yes.
C. 6z = 84; z = 8
Substitute z = 8 into the equation:
6 * 8 = 48
This is not equal to 84, so the answer is No.
So the answers are:
A. No
B. Yes
C. No
