What is the answer for -7x= -96

Darina [25.2K]

Hello!

To solve, this, perform the opposite operation of what is being done on both sides. Here, we see x being multiplied by -7. The opposite operation of multiplication is division.

Therefore, to solve this, divide both sides by -7.

-7x = -96

-7x / -7 = -96 / -7

x = -96/-7

When you divide two negative numbers, they become a positive.

x = 96/7

This cannot be simplified further as a fraction, but if you would like the exact decimal, it is about 13.714.

Hope this helps!

Answer:

the answer is A.

Step-by-step explanation:

After multiplying the two fractions: $\frac{-7}{4} * \frac{5}{3} = \frac{-35}{12} = -2\frac{11}{12}$

You might also want to consider that it's negative because it's BELOW sea level. If you are going down, that wount mean that it is negative. So after mltiplying and turning the result into a proper fraction, you get A as your final answer.
