-10t = -10
Divide each side by -10
-10t ÷ -10 = -10 ÷ -10
t = 1
Answer:
Step-by-step explanation: true
If an average persons heart beats at 103,630 times a day, and a day equals 24 hours, along with the fact that a minute consists of 60 minutes our equations can be:
103,630/(24*60)
To solve the equation we would first start with 24*60 which equals 1440. Then divide 103,630 by that number. Which would equal 71 time per minute.
