Simplify (2/3)^-1 Show your work!

3/2

Step-by-step explanation:

Apply exponent rule: a^-1 = 1/a

(2/3)^1 = 1/2/3

Apply the fraction rule: 1/a/c = c/b

3/2

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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
