Question

-5m < 10

m < -2
m > -2
m < -50
m > -50

The correct answer is: m > -2

$negative 5 m less than 10 m u l t i p l y space b y space fraction numerator negative 1 over denominator 5 end fraction space b o t h space s i d e minus 5 m space cross times space fraction numerator negative 1 over denominator 5 end fraction space greater than space 10 space cross times fraction numerator negative 1 over denominator 5 end fraction o n space s o l v i n g m greater than negative 2$

remember this when we multiply by negative sign
inequality sign will change

To solving an equation that uses division, such as n/8 = 7, Find inverse operation should you use to solve for n.

we use multiplication inverse to solve for n, because we have to remove denominator(1/8) in this question
