Grant rents a car to visit family. The closest rental company charges $40 a day plus $0.30
per mile. Grant is not able to spend more
than $150 for the rental and he needs the
car for 2 days. Write an inequality that can
help Grant determine how many miles, m, he
could travel on his budget
.Use the number line to represent the solution to the inequality written.

Step-by-step explanation:

The interior angles of all triangle add to equal 180 degrees. This means you can set the measures of all these angles equal to 180 and solve algebraically for x.

    180 = (2x - 10) + (x + 30) + 70
    180 = 2x - 10 + x + 30 + 70
    180 = 3x + 90
    90 = 3x
    30 = x

To find m∠A, substitute 30 for x into 2x - 10.

    2x - 10
    2(30) - 10
    60 - 10
    50

m∠A = 50°
