Solve 60+0.60mleq0+.80m

$$60 + 0.60 m \leq 0 + .80 m$$

Solve for m

$$m\geq 300$$

Solution Steps

Anything plus zero gives itself.

$$60+0.6m\leq 0.8m$$

Subtract 0.8m from both sides.

$$60+0.6m-0.8m\leq 0$$

Combine 0.6m and -0.8m to get -0.2m.

$$60-0.2m\leq 0$$

Subtract 60 from both sides. Anything subtracted from zero gives its negation.

$$-0.2m\leq -60$$

Divide both sides by -0.2. Since -0.2 is negative, the inequality direction is changed.

$$m\geq \frac{-60}{-0.2}$$

Expand \frac{-60}{-0.2} by multiplying both numerator and the denominator by 10.

$$m\geq \frac{-600}{-2}$$

Divide -600 by -2 to get 300.

$$m\geq 300$$
