How do you find the slope?“The cost y(in dollars) to rent a kayak is proportional to the number x of hours that you rent the kayak. It costs $27 to rent the kayak for 3 hours.”

Answers

Answer:

9/1

Step-by-step explanation:

$27 for 3 hours. To find the slope, it always has to be over 1 hour because it's a unit rate. 27/3 would be 9. It makes sense too because $9 per 1 hour is the same as $27 for 3 hours.

Answer:

the slope is 9

Step-by-step explanation:

The slope is how much it cost per hour so that means if you do 27 divided by 3 then you get 9 cause 3 hours is 27 but one hour is 9

how you check if your right is by adding 9 up 3 times

9+9+9=27

Write an equation or inequality to represent "five times the difference of a number n and forty two is ten more than twice the product of a number x and number y."

Answers

Five times the difference of a number n and forty two is ten more than twice the product of a number x and number y

  • Five times: 5 ×
  • difference of a number n and forty two: (n - 42)
  • is: =
  • twice the product of a number x and a number y: 2(xy)
  • ten more than: + 10

Rewrite the expression into an equation.

5(n - 42) = 2(xy) + 10

5(n-42)=10+2(xy)

beth needs 5 1/4 quarts of paint to paint some walls .if paint cost $13.99 for one quart how much will it cost her

Answers

In this question all the details required to solve the problem is already provided. Firstly the fraction given for the amount of paint required needs to be simplified for future use. then we have to get to the problem.
Beth requires 5 1/4 quarts of paint to paint some wall
Cost of 1 quarts of paint = $13.99
Amount of paint required by Beth = 5 1/4
                                                     = 21/4
Cost of 21/4 quart of paint = (13.99 * 21/4)
                                           = 293.79/4
                                           = 73.45
So Beth requires $73.45 worth of paint to paint the amount of wall she desired.
It will cost Beth $73.45.You can multiply 5 by 13.99 to get how much 5 quarts costs.5 x 13.99=$69.95Now, how do we find how much 1/4 of a quart costs? You just divide 13.99 by 4.13.99 / 4=$3.4795All you have to do now is just add the cost of 5 quarts to the cost of 1/4 of a quart.69.95 + 3.4795=$73.4475Now you just round to get your final answer.$73.4475 >> $73.45
