Deanna and Lisa are playing games at the arcade. Deanna started with $15, and the machine she is playing costs $0.75 per game. L

Answer: After they've played 8 games, they will have the same amount of money remaining.

Step-by-step explanation:

Represent the number of games by the variable x and the remaining amount of money by the variable y.

Deanna's situation can be represented by the equation y = 15 - 0.75x

Lisa's situation can be represented by the equation y = 13 - 0.50x

Now to find out how many games they will have the same amount of money remaining, you have to use substitution and solve for x.

15 - 0.75x = 13 - 0.50x

-13 -13

2 - 0.75x = - 0.50x

+0.75x +0.75x

2 = 0.25x

x = 8

On the blue prints for a house, 2 inches represents 3 feet. If the width of a room on

lisabon 2012 [21]

Answer:

The actual width would be 9.75 feet. (I think).

Step-by-step explanation:

If two inches represents three feet, then two inches also represents thirty-six inches. You would then have to set up the proportion $\frac{2}{36} = \frac{6.5}{x}$ . Solving that proportion would get you an answer of 117 inches, equal to 9.75 feet. I hope this helps! :)

Tobias rented a kayak from a sports equipment store.

Ket [755]

Answer:

B

Step-by-step explanation:

Let x = every day he rented the kayak

Since the store charges $60 for each day, multiply x by 60 like this: 60x

They also have $25 on top of that; 60x + 25

This all has to equal $325; 60x + 25 = 325

To solve for x, subtract 25 from both sides

60x + 25 = 325

- 25 - 25

60x = 300

Divide both sides by 60

60x/60 = 300/60

x = 5

This means Tobias rented the kayak for 5 days

Find the measure of the missing side. Round your answer to the nearest tenth. (PYTHAGOREAN THEOREM)

Burka [1]

Answer:

Rounded to the nearest tenth, the length of the missing side is 5.4 in.

Step-by-step explanation:

According to the Pythagorean theorem, $a^{2}+b^{2}=c^{2}$ , where c is the length of the hypotenuse (the longest side), a and b are the lengths of the other two sides. We can use this to solve for the length of the hypotenuse of the right triangle shown in your question (the missing side):

$2^{2}+5^{2}=c^{2}$

This simplifies to $29=c^{2}$ . Now to solve for c (the length of the hypotenuse), we just take the square root of both sides of the equation and solve like so:

$\sqrt{29} =\sqrt{c^{2}}$

This simplifies to c≈5.4 in.
