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. s olve 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
