Answer:

x = 10; WX = 5; HJ = 10

Step-by-step explanation:

The hash marks indicate that points W and X are midpoints of their respective segments. That makes WX a midline of the triangle. The midline is always half the length of the base (HJ). We can use this fact to write an equation relating the lengths.

HJ = 2·WX

x = 2(x -5) . . . .substitute the given expressions

x = 2x -10 . . . . eliminate parentheses

10 = x . . . . . . . add 10-x to both sides

This value of x tells you that ...

HJ = x = 10

WX = x -5 = 5

Number 6. I have no idea how to do this because the question doesn’t give enough information

Savatey [412]

${13}^{2} = {5}^{2} \times {b}^{2} \\ 169 = 25 \times {b}^{2} \\ 165 - 25 = {b}^{2} \\ 144 = {b}^{2} \\ \sqrt{ {b}^{2} } = \sqrt{144} \\ b = 12$

!!!HELP AS SOON AS POSSIBLE!!!<br><br> Simplify: -2/9 divided by 3 1/4

ohaa [14]

<h3>Answer: the fraction -8/117</h3>

----------------

First, convert to an improper fraction

3 & 1/4 = 3 + (1/4)

3 & 1/4 = (12/4) + (1/4)

3 & 1/4 = 13/4

The mixed number 3&1/4 turns into the improper fraction 13/4

---------------

-2/9 divided by (3&1/4) = -2/9 divided by 13/4

To divide two fractions, you flip the second one and then you multiply

"-2/9 divided by 13/4" turns into "-2/9 times 4/13" after this happens

Then you multiply straight across. The numerators stick together. The denominators stick together.

numerators: -2*4 = -8

denominators: 9*13 = 117

We end up with the fraction -8/117

This cannot be reduced as there are no common factors (other than 1) between 8 and 117.
