Question

Which number line represents the solution to 2.5 – 1.2x < 6.5 – 3.2x?

Answer 1

So, the answer is C.

Answer 2

x<2

Explanation:

2.5 – 1.2x < 6.5 – 3.2x

Sovle the inequality for x

2.5 – 1.2x < 6.5 – 3.2x

Add 3.2x on both sides

2.5 +2x < 6.5 – 3.2x

Subtract 2.5 from both sides

2x< 4

divide by 2 on both siddes

x<2

now make a number line

for < symbol we use open circle and we shaded left

So draw a open circle at 2 and shade to the left of 2
