Which number line below shows the set of numbers graphed correctly

The number line shows the graph of an inequality: A number line is shown from negative 5 to positive 5 with increments of 0.5. All the whole numbers are labeled on the number line. An empty circle is shown on the third mark to the left of 0. The region to the left of the empty circle is shaded. Which statement explains whether −3.5 can be a value in the shaded region? Yes it can, because −3.5 lies to the right of −1.5. No it cannot, because −3.5 lies to the left of −1.5. Yes it can, because −3.5 lies to the left of −1.5. No it cannot, because −3.5 lies to the right of −1.5.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
