Which expression can be used to check the answer to 56 divided by (negative 14) = n?

Natalka [10]

For this case we have the following expression:

$\frac {56} {- 14} = n$

To verify the answer we have:

Multiplying both sides of the equation by -14:

$- (14) * \frac {56} {- 14} = n * (- 14)\\56 = n * (- 14)$

Thus, the answer can be verified with:

$56 = n * (- 14)$

Answer:

$56 = n * (- 14)$

Holly drove 100 miles in 4 hours, and Yemi drove 100 miles in 5 hours. How can you compare the speeds of Holly and Yemi? Explain

Lelu [443]

The first thing that yo do is divide 100 by 5 for Yemi and that's how fast she drove which is 20 miles per hour. And then you do the same thing for Holly 100 divided by 4 which is 25 mph. So Holly is driving faster than Yemi. So you can compare them by dividing the miles by hours for both of them.
