The cost for one steak burger is $4.5. The price/ The cost of one order of fries is $2.25
<h3>Solution</h3>
Let one steak burger cost $x
and one fries order cost $y
Hence, we have
3x+2y = 18-----------1
2x+3y = 15.75-------2
<h3>Let us solve the
equation simultaneously</h3>
multiply equation 1 by 2 and equation 2 by 3
6x + 4y = 36 ---------3
6x + 9y = 47.25 ----4
subtraction 4 from 3 we have
0x -5y = -11.25
Divide both sides by -5
y = 11.25/5
y = $2.25
Put y = 2.25 in equation 1 to find x
3x+2(2.25) = 18-----------1
3x + 4.5 = 18
3x = 18 -4.5
3x = 13.5
x = 13.5/3
x = $4.5

Answer:

Step-by-step explanation:
First you need to factor your quadratic equation. You'll get (2x+1)(2x+1). Your two zeroes will be -1/2 and -1/2 with one being a, the other b. So then
a/b = (-1/2)/(-1/2)
and
b/a = (-1/2)/(-1/2)
Both reduce to 1. So a/b + b/a is 1+1=2
Answer:
Step-by-step explanation:
3x² + 5x + 2 = 3x² + 3x + 2x + 2
=3x*(x + 1) + 2*(x + 1)
= (x + 1)(3x + 2)
