Adrian is using an indirect method to prove that segment DE is not parallel to segment BC in the triangle ABC shown below:

VikaD [51]

If we start with the assumption that segment DE is parallel to segment BC, then we the similarity condition that:
triangle ABC is similar to triangle ADE
For this to be true, the ratio corresponding sides of the two triangles must be equal. So:
5/8 =? 6/10
But
5/8 =/= 6/10

So, DE is not parallel to BC

Problem 1:

kondor19780726 [428]

Answer:

1) The variable is x

2) $1.5x > 51$ Solving the inequality we get x>34

3) $5b > 51$ , solving the inequality we get b>10.2

Step-by-step explanation:

1. Define the variable:

The variable is x

2) Trini needs more than 51 cubic feet of soil to top up his raised garden. Each bag of soil contains 1.5 cubic feet. Write and solve an inequality to find how many bags of soil Trini needs.

$1.5x > 51$

Solving the inequality

$x>\frac{51}{1.5}\\x>34$

Solving the inequality we get x>34

3) Write the inequality:

5 times b greater than 51

$5b > 51$

4) Solving the inequality

$5b > 51\\b>\frac{51}{5}\\b>10.2$

So, solving the inequality we get b>10.2
