For this case, the first thing we must do is define variables.
We have then:
x: Maggie's age
y: Age of Maggie's brother
We write the system of equations that models the problem.
We have then:

We solve the system of equations.
For this, we use substitution:

From here, we clear the value of x:


Answer:
Maggie is 9 years old
19 yards divided by 2.5 minutes.
=19/2.5
= 7.6 yards/minute
There are 12 inches per foot. If the tree is 48 feet tall, it is 48 x 12 = 576 inches tall.
All of these points have the same y coordinate so this is a horizontal line which has a slope of 0.
