Answer:

10 hour rental

Step-by-step explanation:

Let x = number of hours

HD cost: 7x + 65

L cost: 4x + 95

Set the two cost expressions equal and solve for x, the number of hours.

7x + 65 = 4x = 95

3x = 30

x = 10

The costs are equal for a 10 hour rental.

An amateur soccer ball is priced at
Oduvanchick [21]

Answer: $26

Step-by-step explanation:

   If $19.50 is 3/4, we need to find 4/4.

3/4 -> 0.75

4/4 -> 1

    We will set up a proportion and solve.

\frac{19.5}{0.75} =\frac{x}{1}

19.5 = 0.75x

26 = x

         The professional ball is $26.

Not sure how I would solve this
suter [353]
<h3>Answers:</h3>

The first ordered pair is   ( -4 , -3 )

The second ordered pair is   ( 8, 3 )

=================================================

Explanation:

The first point is (x,-3) where x is unknown. It pairs up with y = -3 so we can use algebra to find x

x-2y = 2

x-2(-3) = 2 ... replace every y with -3; isolate x

x+6 = 2

x = 2-6

x = -4

The first point is (-4, -3)

---------------------------

We'll do something similar for the other point. This time we know x but don't know y. Plug x = 8 into the equation and solve for y

x-2y = 2

8-2y = 2

-2y = 2-8

-2y = -6

y = -6/(-2)

y = 3

The second point is (8, 3)

I really don't understand help
Zielflug [23.3K]

Answer:

128 ft sq.

Step-by-step explanation:

The way you find the area of a square is by multiplying one side by another, and since it is a square, the sides are the same. This means that if we have a square with a side length of x, the way to find the area of that square is to multiply x by x, which can be written as x^2. Now, since we're doubling this, we can say that double Mary's garden is 2 * x^2. If we substitute 8 in for x, we have to multiply 8^2 by 2 or 8 by 8 by 2 to find our answer. 8 times 8 is 64 and 64 times 2 is 128.
