The formula for calculating simple interest is i = prt. which is the equivalent equation solved for r? l/pt=r pt/l=r l-pt=r l+pt=r

I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing.

I = PRT

I / P = RT to divide both sides by P

I / PT = R to divide both sides by T

So I / PT = R (the first choice) is the equation solved for R.

I=prt

solving for r

we need to isolate r on the left side

so dividing both sides by pt , we get

r=I/pt

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
