Question

If anyone can help me on these three problems that would be great :)

Answer 1

3) -1 = A

4) 5 = C

5) Yes

Explanation:

5) 2x + 5 = 5x - 7

- 5x - 5x

_________________

-3x + 5 = -7

- 5 - 5

_____________

-3x = -12

_____ _____

-3 -4

x = 4

RS

`5(4) - 7 = 20 - 7 = 13`

ST

`2(4) + 5 = 8 + 5 = 13`

RT

`2 * 13 = 26`

Since both ST and RS are 13, and doubling them gives

__

you the whole segment of 26, S is the midpoint of RT.

4) To find point C, find the range between everything:

From 8 to 2 → 6

-6 + 2 = -4

-4 = C

3) To find the midpoint, find the range, then take HALF of that range:

From 3 to -5 → -8 [HALF of this would be 4]

3 - 4 = -1

-1 = A

I am joyous to assist you anytime.
