What does m equal?

m/5 + 5 = 7

m =

10

Step-by-step explanation:

First step is to get rid of the 5 on the left side of the equation.  To do this, subtract 5 from both sides like this:

m/5 + 5 - 5 = 7 - 5

The 5s on the left side add to zero so you're left with m/5 + 0.

The right side now is 7 - 5 or 2.

So m/5 = 2.  Now multiply both sides by 5 to get rid of the denominator 5 on the left side.

5 x m/5 = 2 x 5

On the left, 5 divided by 5 is 1 so you now have just m.

On the right you have 2 x 5 or 10

So m = 10

x=30

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
