Answer:

X=-22

Step-by-step explanation:

1/2(x+18)=4(2x-6)-9x

1/2(x+18)=4(2x)-4(6)-9x

1/2(x+18)=8x-24-9x

1/2(x+18)=-x-24

2*1/2(x+18)=2(-x-24)

x+18 = -2x-48

x+2x+18 = -2x+2x-48

3x+18 = -48

3x+18-18 = -48-18

3x = -66

3x/3 = -66/3

x = -22

Pls help solve question 3

Lelu [443]

Answer:

If m is the midpoint of ab it means am is equal to mb

am = 3x + 8 and mb = 6x-4

and ab = am + mb

first find the value of x by using am = mb

3x + 8 = 6x - 4

8 + 4 = 6x - 3x

12 = 3x

x = 4

ab = 3 (4) + 8

= 12 + 8 = 20 = mb

ab = am + mb

= 20 + 20

so, the value of ab is 40
