The answer to the question is
5r= 28
r= 28/5
This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
A^2=B^2+c^2
8^2+15^2=X^2
so 289=X^2
the square root or 289 is 17, so the answer is 17ft
72 days
there are 720 ounces total (convert 45 pounds to 720 ounces)
divide that by the 10 ounces per day and get 72 days
