Answer: In order to save money for a 1 day rental with plan B, the number of miles must be greater than 153.84 miles
Step-by-step explanation:
Let x represent the number of miles driven with either plan A or B.
Plan A: 30 dollars per day and 13 cents per mile. It means that the cost of renting the car or one day and driving x miles is
30 + 0.13x
Plan B: 50 dollars per day with free unlimited mileage. It means that the cost of renting the car or one day and driving x miles is 50
In order to save money for a 1 day rental with plan B, the number of miles would be
50 < 30 + 0.13x
50 - 30 < 0.13x
20 < 0.13x
0.13x > 20
x > 20/0.13
x > 153.84 miles

Answer:
D
Step-by-step explanation:
A difference of squares is represented in general as
a² - b²
Both variables have an even power (2) → a
There are only two terms → b
An addition sentence is just addition.
1 3/4 + 1 1/3 + 1 3/4 = ?
7/4 + 7/4 + 4/3
First find the lowest common denominator.
21/12 + 21/12 + 16/12
= 58/12 = 4 10/12 = 4 5/6
