This inequality has 5 solutions, 0, 1, 2, 3, 4
Solving for y right?
2y = 3x + 4 - x
2y = 2x + 4
y = 2x + 4 over 2
y = 2 (x + 2) over 2
y = x + 2
y - 3 = 2x - 6 over 2
y - 3 = 2(x - 3) over 2
y - 3 = x - 3
y = x
x - y - 2 = 2(2x + 1)
-y - 2 = 2(2x + 1) - x
-y = 2(2x + 1) - x + 2
y = -2(2x + 1) + x - 2
The answer is 57.49°

1° = 60'
x° = 29'
1 : 60 = x : 29
x = 29 * 1 : 60 = 0.48°
<u>29' = 0.48°</u>
1° = 3600''
x° = 38''
1 : 3600 = x : 38
x = 38 * 1 : 3600
x = 0.01°
<span><u>38'' = 0.01°</u>
