Answer:

y=100

Step-by-step explanation:

You can solve this by comparing the ratio.

The first set is 10:20 or 1:2 when simplified.

This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.

What is the solution set? −9.5x−1.5&gt;−30<br> x= ?
Alborosie
Hi there!

x > 0.073171.
Why?

First to solve we need to add 30x to both sides of the inequality.

-9.5x - 1.5 + 30x > -30x + 30x
20.5x - 1.5 > 0

Next we need to add 1.5 to both sides.

20.5x - 1.5 + 1.5 > 0 + 1.5
20.5x > 1.5

Finally, divide both sides by 20.5.

20.5x/20.5 > 1.5/20.5

x > 0.073171

So our answer is x > 0.073171.

Hope this helps!
