-$$\frac { - t } { 8 } = 21$$
A) $- 168$
B) $- 147$
C) $- 29$
D) $- 160$

Question

Quizplus · Accepted Answer

To solve for t, we can use the multiplication principle, which states that if we multiply both sides of the equation by the same non-zero number, the equality still holds. In this case, we can multiply both sides by -8 to isolate t:

$$\frac {-t}{8} = 21$$

$$-t = 21 \cdot (-8)$$

$$-t = -168$$

$$t = 168$$

Therefore, the correct answer is choice A, -168.

Solve Using the Multiplication Principle −t8=21\frac { - t } { 8 } = 218−t​=21

Solve Using the Multiplication Principle $\frac { - t } { 8 } = 21$
