What is m if 4÷ (5m^2) = (9÷m) + (2÷ 10m)

Good evening Brainiac

4/5m^2 = 9/m + 2/10m

4/5mm = 9/m + 2/10m

Now we should multiply all terms by mm and cancel

So we'll have

4/5 = 9m+2m/10

4/5 = 46/5 m

Now flip the equation so we can feel more comfortable with the side

46/5 m = 4/5

m= 2/23

I hope that's help:)

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
