Whaaaaaaaaaaaaat????

Answer:

  7 pizzas

Step-by-step explanation:

For a difference in price of $58 -25 = $33, a customer gets a difference in number of 5 -2 = 3 pizzas. Then a pizza costs $33/3 = $11.

The cost of 2 pizzas is $22, so the delivery charge is $25 -22 = $3.

For $80, after subtracting the $3 delivery charge, $77 goes to the cost of pizzas. For that amount, $77/$11 = 7 pizzas will be delivered.

Sally used all of the paint shown to make a certain tint of orange paint. How many pints of red paint should be mixed with 24 pi
ruslelena [56]

Answer:

18 pints

Step-by-step explanation:

As we can see, three pint of yellow paint was mixed with four pint of red paint. Let x represent the number of yellow paint and let y represent the number of red paint. Therefore, the ratio of the two paints is:

x/y = 3/4

x = (3/4)y

To calculate the number of red paints (x) that is needed to be mixed with 24 pints of yellow paint, we use the equation and substitute y as 24. Hence:

x =  (3/4)y

x =  (3/4) * 24

x = 18 pints
