Help!!! WITH Solve each inequality and graph the solution on the number line. ​

w - 7 > - 4        To solve the inequality, you need to get the variable (w) by itself, to do so, you add 7 on both sides of the inequality

w - 7 + 7 > -4 + 7

w > 3     [w is a number greater than 3]

(If you are using an open circle and closed circle, otherwise you can skip)

When the sign is < or >, you have an open circle "o"

When the sign is ≤ or ≥ (less/greater than or equal to), you have a closed circle

Make an open circle on the number 3, then make an arrow pointing to the right because w is greater than 3.

If you don't have to do the open/closed circle, just make a dot on the number 3 and make an arrow pointing/going to the right

Morgarella [4.7K]

Answer with step-by-step explanation:

The way the question is worded, this actually shouldn't be correct. The correct answer should be 3:4.

Because the trapezoids are similar, we can find the ratio of their perimeters by actually just finding the ratio of their sides.

Why?

By definition, the corresponding sides of a polygon are in a constant proportion. The perimeter is simply the sum of all sides of the polygon. Since we're just adding the sides, the proportion will still be maintained.

Therefore, we'll just need to ratio of their corresponding sides. The only two corresponding sides that are marked are \overline{RS} and \overline{AB}.

The ratio of \overline{RS}:\overline{AB} is 18:24\implies \boxed{3:4}.

The reason why it ideally should be 3:4 and not 4:3 is because the question states RTSU\sim ABCD, which mentions RSTU first, so our answer should follow this respective order. I believe you were marked right anyways because the specific order is not specified, but generally, you want to give your answer respectively by default.
