Answer:
n = 3
Step-by-step explanation:
8n - (3n + 4) = 11
8n - 3n - 4 = 11
5n = 11 + 4
5n = 15
n = 3
This is a pretty complex problem
First we have to find a common denominator
8×3=21
7/8×3=21/24
2/3×8=16/24
21-16=5
answer is 5/24
Answer:
x ≤ 3
Step-by-step explanation:
2(4+2x) ≥ 5x+5 (by PEDMAS, expand parentheses first)
4(2) + 2x(2) ≥ 5x + 5
8 + 4x ≥ 5x + 5 (subtract 8 from each side)
4x ≥ 5x + 5 - 8
4x ≥ 5x - 3 (subtract 5x from both sides)
4x -5x ≥ - 3
-x ≥ - 3 (multiply both sides by -1, remember to flip the inequality when multiplying both sides by a negative number)
x ≤ 3
