Therefore, the number of beats will pass before he again strikes them at the same time is 84
Answer:
B
Step-by-step explanation:
The answer is b because the lines outside -65 are symbols for absolute value. Absolute value means the distance away from 0, so b would be an appropriate choice.
M-5-(-12) would equal m+7 because there is a negative before the parentheses and in the parentheses which means you would change it to a positive so, negative 5 plus positive 12 is 7 and since the 7 is positive you would add m (hope this helped)
Velocity=Distance/Time
Time(t)=Distance/Velocity
