Answer 1

Answer:

The answer is 27 miles in the morning and 85 miles in the afternoon.

Step-by-step explanation:

So first you have to set up an equation.

X represents: the number of miles they rode in the morning.  

3X + 4 represents: 4 more than 3 times this many in the afternoon

3X+4 + X = 112 represents: adding the morning miles and the afternoon miles together to get the total trip of 112 miles

Your equation to solve  3X+4+X =112

Now you can solve the equation

3X+4+X =112

Combine like terms (x's)

3X + X = 4X

4X+4=112

Subtract 4 from each side:

4X+ 4 - 4= 112-4

4-4 = 0 and 112-4 = 108

4X = 108

Divide both sides by 4

4X/4 = 108/4

4/4 = 1X and 104/4 = 27

X = 27

Remember X represents the number of miles they rode in the morning, so they rode 27 miles in the morning.  

Remember 3X+4 represents the number of miles they rode in the afternoon.

3X+4 =  

3(27)+4 =  

81+4 =  

85 miles.

That means in the afternoon, they rode 85 Miles
