Step-by-step explanation:

Distance Formula in Pic

You just plug in the numbers for x1,y1 and x2,y2

A is your x1 and y1

B is your x2 and y2

after plugging it you do PEMDAS and solve it

John bought 18 pizzas. Mitchel bought 12 pizzas. What percent of the total number of pizzas Mitchel buy?

mina [271]

Answer: 40%

Step-by-step explanation: The total number of pizzas is 12 + 18 = 30. Mitchel bought 12 of those 30 pizzas. To find the percentage you do the portion/total. Thus 12/30 = 0.4, as a proportion. To turn a proportion into a percentage simply multiply by 100. 0.4 * 100 = 40%

A theater charges $5.00 admission for adults and $2.50 for children. At one showing 240 admissions brought a total of $800. How

SOVA2 [1]

Answer:

Step-by-step explanation:

Let the number of adults be x

Let the number of children be y

This means that the money paid by adults and kids is $5 multiplied by x (5x) and $2.50 multiplied by y (2.5y)

This will give two equations as shown below

x + y = 240 total admissions......................... equation 1

5x + 2.5y = 800 total money paid..................equation 2

Making x the subject of formula in equation 1

x=240-y......................................................equation 3

Substituting equation 3 into equation 2

5(240-y) + 2.5y = 800 removing the brackets

1200 - 5y + 2.5y = 800 grouping like terms

-5y + 2.5y = 800-1200 simplifying

-2.5y = -400 therefore

-2.5y/-2.5 = -400/-2.5

y = 160

Substituting y into equation 3

x = 240 - y

x = 240 - 160

x = 80

Hence number of adults who attended = 80
