5 3/4 miles

Step-by-step explanation:

First thing you want to do is to make the fractions have the same denominator.

3 1/4 turns into 13/4

2 1/2 turns into 5/2 turns into 10/4

Next you add them together

13/4 + 10/4 = 23/4

Then you simplify

23/4 turns into 5 3/4

angle addition postulate

2x=56

step-by-step explanation:

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

2

=
