Make r the subject of the formula in p+q=5r/2
To make r the subject of the formula in p+q=5r/2, we need to isolate r on one side of the equation.
First, let's multiply both sides of the equation by 2 to get rid of the fraction:
2(p+q) = 5r
Next, divide both sides of the equation by 5 to solve for r:
r = (2(p+q)) / 5
Therefore, r is the subject of the formula when p+q=5r/2 is rearranged.
To make r the subject of the formula in p+q=5r/2, we need to isolate r on one side of the equation.
Step 1: Distribute the fraction:
p + q = (5r)/2
Step 2: Multiply both sides of the equation by 2 to remove the fraction:
2(p + q) = 2(5r)/2
2p + 2q = 5r
Step 3: Divide both sides of the equation by 5 to isolate r:
(2p + 2q)/5 = (5r)/5
(2p + 2q)/5 = r
Therefore, the formula with r as the subject is:
r = (2p + 2q)/5
