Answer:

x = 9

TH = 12

Step-by-step explanation:

since TM is half of HM, the equation is:

2(21 - x) = 3x - 3

42 - 2x = 3x - 3

45 = 5x

x = 9

TH = 21 - x

TH = 21 - 9

TH = 12

Solve for x<br> pls show work<br> 1/2x + 4 = 1/8x + 88
SVETLANKA909090 [29]

Answer:

224

Step-by-step explanation:

1/2x-1/8x=88-4

4/8x-1/8x=84

3/8x=84

x=84/(3/8)

x=(84/1)(8/3)

x=672/3

x=224
