Exact form: 3/2
decimal form:1.5
mixed number: 1 1/2
Replace a and b in the equation with their values given:
-0.5(7(-6)-12(-10)-(8.4(-10)-14(-6))
Multiply within the parentheses
-0.5(-42 + 120) -(-84 + 84)
Add inside the parenthesis:
-0.5(78)-0
Multiply:
-.05 x 78 = -39
The answer is -39
Let's come up with variables to substitute and make an equation.
T = total number of minutes
P = number of minutes used by each person in the phone plan
R = remaining minutes per month
R=T-3P
Now that we have an equation, we can substitute the numbers we are given in the problem to find the final solution.
R= 675- 3(250)
R= 675- 750
R= -75 minutes
There are no remaining minutes, and in fact, the people on the phone plan have used 75 extra minutes than provided for in their phone plan.
