Answer:
√(r+n)/5=m
Step-by-step explanation:
r=5m²-n
adding n on both sides
r+n=5m²-n+n
r+n/5=m²
taking square root on both sides
√(r+n)/5=m
Answer:

Step-by-step explanation:
Heart rate will be represented by
, minutes will be represented by
.
Here's the equation I came up with:

We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.

This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.
I hope this helps!
Answer:
x=23
Step-by-step explanation:
let's make this question into equation form
x increase by 10; or x+10
is equal to 33; or =33
so it would look like this; x+10=33
now we can solve it in reverse
<em>33-10=23</em> so x is 23.
hope this helped, have a great day.
