Your answer would be R=-5x-4+y
Answer:
<em>20%</em>
Step-by-step explanation:
<em>First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.</em>
The answer is really 1 5/6 because 5/6 + 2/3=5/6 NOT 7/3 so of course she is wrong
We will use the equation

to solve this one. We have distance and time, so we'll rearrange this to:

So she runs 7.5 miles per hour.
