Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.
he usually plans to stop and rest for about 5 minutes.
m represents the total minutes.
12 calories per minute.
for m minutes the calories burn is 12m
He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes
So expression becomes 12(m-5)
He wants to burn 540 calories. So we set the calories = 540
The equation becomes ,
12(m-5) = 540
Now we solve for m , total number of minutes
12(m-5) = 540(divide by 12 on both sides)
m - 5 = 45
m = 50 ( add 5 on both sides)
Anzelm should plan to be out jogging for 50 minutes
Answer:
1 Hour
250 + 150h = 500
Step-by-step explanation:
So, the fee for the meeting is 250. The hourly fee is 150. Let h equal the number of hours.
250 + 150h
If pablo has 500, then we cannot exceed that amount. So, our equation becomes
250 + 150h = 500
Subtract 250 from both sides
150h = 250
And divide by 50 on both sides. You get x = about 1.67. Since this is a question about time and money, you would round down to 1.
