1. solve the proprotion k/5=5/125. a) 1/25 b) 25 c) 5 d) 1/5 2. round the answer of 0.4x-0.2=2.5 to two decimal places. a) -2.70 b) -6.75 c) -5.75 d) -3.25 3. what is the y-intercept of 4x-3y=-12? a) -4 b) 3 c) -3 d) 4

1. solve the proportion k/5=5/125.
First reduce 5/125.
5/125 = 1/25
Now you can cross multiply.
25k = 5
k = 5/25
k = 1/5
d) 1/5

2. round the answer of 0.4x-0.2=2.5 to two decimal places.
0.4x=2.7
x = 6.75
b) -6.75

3. what is the y-intercept of 4x-3y=-12?
The y-intercept is when x = 0.
4(0) - 3y = -12
-3y = -12
y = 4
d) 4

The first answer is correct
