Answer: cheese pizzas = 25 , Pepperoni pizzas = 15
Step-by-step explanation:
Let x = Number of cheese pizzas, y = Number of pepperoni pizzas.
As per given,

Multiply 7 on both sides of (i), we get

Eliminate (iii) from (ii), we get

Put value of y in (i) , 
Hence, cheese pizzas = 25 , Pepperoni pizzas = 15
<span> x^2 +(x-4)^2 =20^2</span>
<span> x^2 +(x-4)^2 =400</span>
x^2 +(x-4)^2 -400=0
factor:
2x^2-8x-384=0
Factor the 2 out of 2X^2
2(x-16) (x+12) =0
<span> Divide both sides by 2</span>
(x-16) (x+12) =0
X=16 , x=-12
<span> Number cannot be negative so x=16</span>
For this case we have the following expression:

We apply distributive property, which by definition establishes that:

So:

Answer:

Answer: 6 11/24
Step-by-step explanation:
