Luigi uses 39 cups of flour for every 6 pizzas he makes.Complete the table using equivalent ratios. Pizzas
zlopas [31]

Answer:

Part 1) The number of cups of flour needed to make 4 pizzas is 26

Part 2) The number of pizzas Luigi can make with 13 cups of flour is 2

Step-by-step explanation:

we know that

Luigi uses 39 cups of flour for every 6 pizzas he makes

Let

y ----> the number of cups of flour used

x ---> the number of pizzas he makes

In this problem

The relationship between the variables x, and y, represent a proportional variation

we have the ordered pair (6,39)

so

\frac{y}{x}=\frac{39}{6}

Part 1) Find out the number of cups of flour needed to make 4 pizzas

using a proportion

\frac{y}{4}\ \frac{cups\ of\ flour}{pizzas}=\frac{39}{6}\ \frac{cups\ of\ flour}{pizzas}

Solve for y

y=\frac{39}{6}(4)

y=26\ cups\ of\ flour

Part 2) Find out the number of pizzas Luigi can make with 13 cups of flour

using a proportion

\frac{13}{x}\ \frac{cups\ of\ flour}{pizzas}=\frac{39}{6}\ \frac{cups\ of\ flour}{pizzas}

Solve for x

x=13(6)/39

x=2\ pizzas
