Renting bowling shoes costs $5. Bowling costs $4 per game. Which equation can be used to find y, the total cost of bowling, if x represents the number of games played.

y = 5x + 4
y = 5 + 4x
y = 5x + 4x
y = 5x - 4

Answers

Answer:

the answer is y=5+4x

Step-by-step explanation:

the indepedndennt variable is 5, since that is the cost of the shoes. you wont be needing a new pair of shoes for every game, therefore it stays constant. 4x represents the number of games times the cost. 4 being the cost per game, x being the amount of games

Four out of five customers ride their

bikes to the shop. On Saturday, 18

customers came in without riding their

bikes. How many rode their bikes?

Answers

72 rode their bikes.

Explanation:
18 did not ride their bike, which makes 1/5. Multiply 18 by 5, which will give you the other 4/5. Subtract 18 from 90, and you will get 72.

The number of people rode their bikes are 72.

Given that, four out of five customers ride their bikes to the shop.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

4/5 customers ride their bikes to the shop.

Number of customers do not ride their bikes to the shop = 1/5

On Saturday, 18 customers came in without riding their bikes.

Let the total number of people ride the bike to shop be x.

So, 1/5 × x = 18

⇒ x = 90

Now, 90-18=72

Therefore, the number of people rode their bikes are 72.

rise over run.. go from point to point. up 5 over 2. 5/2

Answer:

[tex]\frac{5}{2}[/tex]

Step-by-step explanation

There are two methods to your answer. You could use the rise over run method or the formula.

Rise over Run: Start at the point -3 and count up to -2. If you count, that's 5 points up. Then count sideways, then you get 2. so rise (5) over run (2). Your answer would be 5/2.

Formula: The formula is, [tex]\frac{y(2)-y(1)}{x(2)-x(1)}[/tex]. Pick two coordinates. Let's pick (0,-3) and (2,2). Here are the steps:

[tex]\frac{2-(-3)}{2-0}[/tex]

Jill wants to make melonade for her family reunion. She needs enough lemonade for 60 people to each have 1 cup. Write a proportion Jill could use to find the number of gallons of lemonade Jill will need to make. (* do not solve ** must include units )

Answers

Answer:

[tex]\frac{x gallons}{60 cups} =\frac{1 gallon}{15 cups}[/tex]

Step-by-step explanation:

There are about 15.77 cups in a gallon, but I rounded down because .77 cup isn't a full cup. If you aren't supposed to round, use 15.77 instead of 15 and you should get 3.804... gallons needed. If you are supposed to round to nearest whole, use 15. You may have to adjust it depending on the instructions. I hope this helps. Feel free to comment any questions, I will try to respond.

Henry made up a problem about three consecutive odd integers. He said, “The first decreased by the third equals the second decreased by 9.” What integers did he have in mind?​

Answers

Answer: 11, 13, 15

Let the first integer be x.  The second integer is (x + 2) and the third integer is (x + 4).
