This could be done in two ways. If the first number is 4, then you could add 4 with -16. 4 + (-16) is -12. But it could also be -16 + 4, which still equals to -12.

But in the end, your answer is the same : -16 is the other number.

The correct answer is B)x = \frac{y - p + mq}{m}.

In order to find this, we need for follow the order of operations.

y - p = m(x - q) ----> Divide both sides by m

\frac{y - p}{m} = x - q ----> add q to both sides

\frac{y - p}{m} + q = x ---> now we need to give it a common denominator. Multiply the q term by m/m

\frac{y - p + mq}{m} = x

This is our final answer.

5 1/3 divided by 7/8
charle [14.2K]
First convert 5 1/3 into a fraction which is 16/3.
16/3 divided by 7/8 is the same as 16/3 multiplied by 8/7. So you multiply the fractions together to get 128/21.

C, because when you add 45 on both sides, and then after that when you have to subtract 15 in both sides, you get 0 = 120.
