The answer is 48.
<span>Out of 50 people, 4 had a mispriced item: 50 people - 4 mispriced
Out of 600 people, x will have a mispriced item: 600 people - x
Make a proportion:
50 : 4 = 600 : x
50 * x = 4 * 600
50x = 2400
x = 2400 / 50
x = 48</span>
Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+3y=-1
3x+5y=-2
-----------------
3(2x+3y)=3(-1)
-2(3x+5y)=-2(-2)
-------------------------
6x+9y=-3
-6x-10y=4
--------------
-y=1
y=-1
2x+3(-1)=-1
2x-3=-1
2x=-1+3
2x=2
x=2/2
x=1
