First off, let's convert the mixed fraction to "improper", and then check "how many times does 1/3 go into 7 and 5/6?"
Answer:
6 , 2 , 5 , 7 , 4 , 1 , 3
Step by Step:
1) x - 3(10 - 2x) = -2
x - 30 + 6x = -2
7x - 30 = -2
7x = 28
x = 4
2) x + 2(4 - 2x) = 5
x + 8 - 4x = 5
-3x + 8 = 5
-3x = -3
x = 1
3) 5(18 - 4y) + y = 33
90 - 20y + y = 33
90 - 19y = 33
-19y = -57
y = 3
x = 18 - 4(3)
x = 18 - 12
x = 6
4) 8x + 4(13 - 2x) = 52
8x + 52 - 8x = 52
52 = 52
5) x + 3(-11 + 6x) = 5
x - 33 + 18x = 5
19x - 33 = 5
19x = 38
x = 2
6) -6(5 - 2y) - 3y = -2
-30 + 12y - 3y = -2
-30 + 9y = -2
9y = 28
y = 3
2x + 3(3) = 5
2x + 9 = 5
2x = -4
x = -2
7) 2x + 3(10+x) = 45
2x + 30 + 3x = 45
5x + 30 = 45
5x = 15
x = 3

Answer:
Yes, 14 squared is definitely bigger than 3.14. When you square a number, you multiply it by itself, and even if you didn't do that, 14 would still be a bigger number than 3.14.
