Well for the first one you have to subtract 3 on both sides so that would make the equation x > -8 (because a negative subtracting a positive is basically a negative plus negative) and so your equations done. For the second one you divide both ides by -4 so your equation would be x < 4 (the sign would be less then or qual to because you divided by a negative)
Answer:
The interger is up to 27
Step-by-step explanation:
let X represent the number of people.
For fewer than 28 people, we have;
(X ∠28)
Meaning,
(X ∠28) = (X ≤27)
(X = 1) + (X = 2) + (X = 3) ............+ (X = 27)
1 +1 + 1 +...............(27 times)
Therefore, the interger is up to 27

Answer:
x =127
Step-by-step explanation:
Since this is a 6 sided figure, the sum of the interior angles is 720
128+133+112+x+120+100 = 720
Combine like terms
x+593=720
Subtract 593 from each side
x+593-593 = 720-593
x =127
