Ben was in charge of ordering 3636 pizzas for the office party. He ordered three types of pizza: cheese, pepperoni, and suprem

shutvik [7]

Answer:

Ben bought 11 cheese pizzas, 16 pepperoni pizzas and 9 supreme pizzas

Step-by-step explanation:

We can solve this problem with a equation system. I will abbreviate the amount of cheese pizzas he buyed as C, the amount of pepperoni ones as P, and the amount of supreme ones as S. I will also remove the $ notation

The system is given as follows

C+P+S = 36

8C + 11P + 14S = 390

11P = 2*(8C) = 16C

We can easily replace 11P with 16C in equation 2, obtaining

8C + 16C + 14S = 390

24C + 14S = 390

S = (390- 24C)/14 = 195/7 - 12/7 C

Note that, also from equation 3, we have that

11P = 16 C

P = 16/11 C

Now, we can obtain the value of C using equation 1 replacing S and P with the founded values

C+P+S = 36

C + 16/11 C + 195/7 - 12/7 C = 36

C + 16/11 C - 12/7 C = 36-195/7 = 57/7

Taking C as common factor we obtain

C (1+16/11-12/7) = 57/7

C * 57/77 = 57/7

C = (57/7) / (57/77) = 11

Now, we replace this value in the formula we obtain for P and S

P = 16/11 * C = 16/11 * 11 = 16

S = 195/7 - 12/7 * 11 = 63/7 = 9

Now, we verify:

C+P+S = 11+16+9 = 36
8C + 11P + 14S = 8*11 + 11*16 + 14*9 = 88 + 176 + 126 = 390
2(8C) = 2*88 = 176 = 11P

Thus, Ben bought 11 cheese pizzas, 16 pepperoni pizzas and 9 supreme pizzas.

Solve the system of equations. 13x−y=90

Ann [662]

Lets solve the system of equations step by step.
$13x-y=90$ equation (1)
$y=x^2-x-42$ equation (2)

Step 1. Solve for $y$ in equation (1)
$13x-y=90$
$-y=90-13x$
$y=13x-90$ equation (3)

Step 2. Replace equation (3) in equation (2) and solve for $x$ :
$y=x^2-x-42$
$13x-90=x^2-x-42$
$x^2-14x+48=0$
$(x-6)(x-8)=0$
$x=6$ equation (4)
$x=8$ equation (5)

Step 3. Replace equation (4) and equation (5) in equation (3)
(4) in (3)
$y=13x-90$
$y=13(6)-90$
$y=-12$

(5) in (3)
$y=13x-90$
$y=13(8)-90$
$y=14$

We can conclude that the solutions of our system of equations are (6,-12) and (8,14)
