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
