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.

Help with #9 pleaseeee

Answer:

9' - 1.29"

Step-by-step explanation:

Total rise = 5' - 2"

Total run = 7' - 6"

1' = 12" = 1 feet = 12 inches

5' = 5 * 12 = 60"

3' = 7 * 12 = 84"

Total rise = 60" + 72" = 62"

Total run = 84" + 6" = 90"

Length of stringer = hypotenus

Hypotenus = √(total rise² + total run²)

Hypotenus = √(62² + 90²)

Hypotenus = 109.28860"

Convwrting back to feet and inches

= 9' - 1.29"
