Question

Help solving this math homework

Answer 1

8.

33 = 2y + 1 + y - 1

Add the 1 and -1

Add the y and 2y

33 = 3y

11 = y

9, AQ = 2y + 1

2(11) + 1

22 + 1

23

AQ = 23

10, QX = y - 1

QX = 11 - 1

10

QX = 10

11. 62 = 3x - 4 + 3x - 4

Add -4 and -4

Then add 3x + 3x

62 = 6x

Divide 62 by 6x

x = 11 2/3

AB = 3x - 4

3 (11 2/3) - 4

3 * 11 2/3 = 35

35 - 4 = 31

AB = 31

Both sides are equal, so BC also equals 31

12. 206 = 3x - 4  + 3x - 4

206 = 6x

x = 34 1/3

AB = 3x - 4

AB = 3(34 1/3) - 4

AB = 103

Because AB and BC are the same, BC also equals 103.
