Answer:
At 5:15 PM , they will ring together.
Step-by-step explanation:
We have been given that first bell rings every 15 minutes and second bell rings at every 25 minutes.
In order to find when both will ring together again, we can find the LCM of these two numbers.
15 = 3 × 5
25 = 5 × 5
Therefore, LCM of these two numbers is
LCM = 5 × 5× 3
LCM = 75
Hence, 75 minutes = 75/60 = 5/4 hours
Therefore, at 5:15 PM , they will ring together.
B. 54
Because 54+13=67
67+54=121
Answer:
S = 20
Step-by-step explanation:
Answer:
x ≥ -2
Step-by-step explanation:
4x ≥ -8
Since we are solving for x, we are trying to get x alone on one side of the equation. We can easily do this by dividing by 4 on both sides.
4x ≥ -8
4x/4 ≥ -8/4
4x/4 = x and -8/4 = -2
x ≥ -2
