For the pizza of 6 inch

For the pizza of 12 inch

Number calories in a 6-inch pizza = 640 calories, therefore:

Substitute:

And solve for x:

Now, Estimate the number of calories in one slice of a 12 inch pizza:

Answer: 320 calories
Answer:
C is the correct answer
Step-by-step explanation:
A P E X
If y is the number of hours it takes to pour foundations, and x is the number of construction workers, y=k/x, because it takes less time the more workers there are. So 32=k/4 and k=128 and y=128/x. The constant of variation is 128.

Answer:
Multiply the number outside the parentheses by each term inside the parentheses
=2(6.1x+25.3y+2.1x-3.9y)
=(2*6.1x)+(2*25.3y)+(2*2.1x)+(2*-3.9y)
=12.2x + 50.6y + 4.2x - 7.8y
combine like terms
= 16.4x + 42.8y
=4(4.1x+ 10.7)
=(4*4.1x) + (4*10.7y)
=16.4x + 42.8y
Yes, the two expressions are equivalent.
