See explanation

Step-by-step explanation:

One inch is around 2 11/20 centimeters. Therefore, 3 inches would be:

= 3 × 2 11/20

= 3 × 51/20

= 153/20

= 7 13/20

What fraction of an inch is 1 centimeter?

This will be:

= 1 cm / 1 inch

= 1 ÷ 2 11/20

= 1 ÷ 51/20

= 1 × 20/51

= 20/51 inch

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
