Answer:
8.13
Step-by-step explanation:
For this case we must find the quotient of the following expression:

We can rewrite the expression as:
(We take into account that
)

By definition of multiplication of powers of the same base, we place the same base and add the exponents:

By definition of division of powers of the same base, we place the same base and subtract the exponents:

Answer:

to find the value of this expression, it would be easiest to use the distributive property.
(V9)2 +10
= 18V+90V
= 108V

Answer: x=75
Explanation:
x+10+x+20=180
combine like terms
2x+30=180
subtract 30 from each side
2x=150
divide each side by 2
x=75
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

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

Solve for y


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

Solve for x
