Jason paid $15.50 for 3 slices of pizza and 2 burgers. Susan paid $20 for 1 slice of pizza and 4 burgers. Write a system of equation and then determine the cost of each slice of pizza and the cost of each burger.

Answers

Answer 1

Answer:

Answer:

The answer is

3P+2B=15.50

P+4B=20

Where P=pizza slice and B=burger

B=4.45

P=2.20

Step-by-step explanation:

The system proposal is

3P+2B=15.50

P+4B=20

Solving for P in the second equation, we have

P=20-4B and replace in first equation we have:

3(20-4B)+2B=15.50

Solving for B:

B=(60-15.5)/10=4.45

Replace B in first equation

P=20-4B=20-4(4.45)=2.20

What is a quadratic equation?

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is2.

Factor out the 4 first since all numbers are divisible by 4. That leaves us with x² +3x -18.

4( x² +3x -18 ) = 4 ( x² + 6x - 3x -18 )

= 4 ( x(x+6) -3 (x + 6)

= 4 ( x + 6 ) ( x - 3 )

Hence, the factors are 4 ( x + 6 ) ( x - 3 ).
