c (cost)
m (month)
c= xm + b
$424.20= 24.95m+ $49.95
Move everything except variable on one side.
424.20 - 49.95 = $374.24
$374.25 = 24.95m
Divide by 24.95
m = 15

We're told (5,-2) is on the line, that's x=5, y=-2
First one y-5 = -7, (x+2)/3=7/3, not equal
Second one y+5=3, (x-2)/3=1, not equal
Third one y+2=0, (x-5)/3=0, TRUE, equal
Fourth one, y-2=-4 (5+5)/3=10/3, not equal
Answer: third choice y+2 = (1/3)(x+5)
Ok so..
there are a total of 30 socks.
100% would be 30 socks
50% would be 15 socks and
10% would be 3 socks
so the 50% + 10% = 60%
60% - 18 socks
40% - 12 socks
common ratio - 18:12
simplified: 3:2
There is a greater possibility of getting red socks by 3/2 (also 1 1/2)
But I'm kinda stuck between A. and C.
Help anyone?
The answer is 42 because you times 14 by 3
45/100 is 4,500%
2/5 is 40%
18/40 is 45%
15/25 is 60%
