Can you check these?

3. Simplify (56/8+3)*2-1
Ans = (7+3)*2-1
= 10*2-1
= 20-1
= 19

9. A spool of lanyard is 21 yards long. If it is cut into pieces that are each 1.75 yards long, how many pieces of lanyard will there be?
Ans:21/1.75
= 12 pieces

12. (3/5)x - 10 = 1/6
Ans: (3/5)x = 1/6 + 10
(3/5)x = 10 1/6
(5/3)*(3/5)x = 61/6 (5/3)
x = 305/18
x = 16 7/8

13. 6g + 7 + g = -14
7g + 7 = -14
7g = -14 - 7
7g = -21
g = -21/7
g = -3

14. (c/4) - 4 < -7.2
(c/4) < -7.2 + 4
(c/4) < -3.2
(4)(c/4) < -3.2*4
c = -12.8

21. 7.34 - y = 9.06
-y = 9.06 - 7.34
-y = 1.72
y = -1.72

26. 17 - (-4)
= 17 + 4
= 21

36.
