7 because 7 x 7 is 49 but if you add 7 and 7 it gets to 14 7 is the answer
so if you do a different number you will be wrong
Answer:
Your answer of
is correct
Step-by-step explanation:
We begin with the expression: ![-\frac{4}{y} +(-\frac{7}{8y} )](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7By%7D%20%2B%28-%5Cfrac%7B7%7D%7B8y%7D%20%29)
First, we need to find a common denominator, which in this case would be 8y.
To make the first term have a denominator of 8y, we must multiply it by ![\frac{8}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B8%7D)
![-\frac{4}{y}(\frac{8}{8}) +(-\frac{7}{8y} )\\\\-\frac{32}{8y} +(-\frac{7}{8y} )](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7By%7D%28%5Cfrac%7B8%7D%7B8%7D%29%20%20%2B%28-%5Cfrac%7B7%7D%7B8y%7D%20%29%5C%5C%5C%5C-%5Cfrac%7B32%7D%7B8y%7D%20%2B%28-%5Cfrac%7B7%7D%7B8y%7D%20%29)
Now we can add them to get our final answer.
![-\frac{39}{8y}](https://tex.z-dn.net/?f=-%5Cfrac%7B39%7D%7B8y%7D)
Step-by-step explanation:
the answer is

hope this helps bro
Answer:
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour. Now let's say you rode your bike at a rate of 10 miles per hour for 4 hours.
