Answer:

Step-by-step explanation:

Factor the numerator(x+7)(x-5). Then factor the denominator(x+7)(x-3). The x+7 in the top and bottom cancel. So you are left with x-5 in the numerator and x-3 in the denominator.

George's cost per day is

... c = 30 + 0.18m

We want c < 55, so we can write

... 30 + 0.18m < 55 . . . . . your inequality

_____

Here is the solution to the inequality

... 0.18m < 25

... m < 25/0.18

... m < 138.9

George must drive less than 138.9 miles that day.

Answer:

Area: $\frac{8}{15}$ feet²

Perimeter: $\frac{44}{15} =2 \frac{14}{15}$ feet

Step-by-step explanation:

The formula of finding the area of a rectangle or square is width multiplied by length.

The formula of find the perimeter of a rectangle or square is width+width+length+length

Area: $\frac{4}{5} *\frac{2}{3} = \frac{8}{15}$ feet²

Perimeter:

$\frac{4}{5} +\frac{4}{5} +\frac{2}{3} +\frac{2}{3} =$

$\\\\\frac{12}{15} +\frac{12}{15} +\frac{10}{15} +\frac{10}{15} =\\\\\frac{24}{15} +\frac{20}{15} =\\$

$\frac{44}{15} =2 \frac{14}{15}$

What is 4 1/4 -3 3/5

shutvik [7]

First make the denominators the same = 4 5/20 - 3 12/20. Then make them improper fractions= 85/20-72/20= 13/20. Since that is already simplified the answer is 13/20.
