C. 3:2 because that is 6/4 simplified
Answer: x ≥ - 3
5x - 1 ≥ -4(x + 7)
⇔ 5x - 1 ≥ - 4x -28
⇔ 5x + 4x ≥ - 28 + 1
⇔ 9x ≥ - 27
⇔ x ≥ - 3
Step-by-step explanation:
It's 67/100 because a percent is out of 100 which is already simplified
5/7. You are eliminating one of the 8 original lockers yet you still have 5 possible stars left. Hence a probability of 5 stars over 7 possible lockers left. 5/7 = .7143 or 71.43 %
