Solve the equation. show your work step by step. 3x = 45

x=15

Step-by-step explanation:

3x=45

We want to get x by itself, so we divide each side by 3

3x/3 = 45/3

x =15

x = 15

Step-by-step explanation:

We are given the following equation which we are to solve for x:

This is one very simple equation that we need to solve for x.

For that, we will divide both sides by 3 to isolate x and make it the subject of the equation to get:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
