Answer:
Step-by-step explanation:
This equation is written in slope-intercept form, meaning that the value next to the variable (7.50) is the rate (slope) and the other number is the y-intercept (9).
So you can say that you mowed the lawn at $9 up front and 7.50 every hour (or half-hour whatever you want).

Answer:
x = 12
Step-by-step explanation:
Angle Bisector Theorem: PS / PQ = RS / QR
24/14 = x/7
cross-multiply:
14x = 168
x = 12
Answer:
Step-by-step explanation:
Three times a number x : 3x
Three times a number x increase by 4: 3x +4
Five times the number x: 5x
5x = 3x +4
Subtract 3x from both the sides.
5x - 3x = 3x +4 - 3x
2x = 4
Divide both sides by 2
2x/2 = 4/2
x=2
The number is 2
