There are 3 people eating pizza. if each person eats 3/4 of a pizza, how much pizza did they eat altogether?

2¼ pizzas

Step-by-step explanation:

Three people each eat ¾ pizza.

Together they eat 3 × ¾ pizza.

Multiply the numerator by the integer.

3 × ¾ = ⁹/₄

Convert the improper fraction to a mixed number.

⁹/₄ = 2¼

Altogether, they ate 2¼ pizzas.

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
