Question

Can someone help me with both of the or may be one

I’m stuck on both of the question if someone could help me I would highly appreciate:)

Answer 1

30 and 6

Explanation:

Given that R is the midpoint of QS , then

RS = QR , that is

5x = 3x + 6 ( subtract 3x from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

QS = QR + RS

= 3x + 6 + 5x

= 8x + 6

= 8(3) + 6

= 24 + 6

= 30

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

Similarly

QR = RS , that is

6x - 9 = 2x - 1 ( subtract 2x from both sides )

4x - 9 = - 1 ( add 9 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Then

QS = QR + RS

= 6x - 9 + 2x - 1

= 8x - 10

= 8(2) - 10

= 16 - 10

= 6

Answer 2

QS=8x-10

Explanation:

Question 9

6x-9+2x-1

QS=8x-10
