What equation models the problem?

How many weeks will it take Gary to exercise a total of 21 hours?

  4

Step-by-step explanation:

Gary's total exercise time for a week is ...

  3×1.75 hours = 5.25 hours

Then to accumulate 21 hours of exercise time, it will take Gary ...

  (21 hours)/(5.25 hours/week) = (21/5.25) weeks = 4 weeks

4 weeks

Step-by-step explanation:

Equation :

21  / 1.75 x 3 = Weeks needed

To calculate

1.75 hours = 1 hour and 45 mins

= 105 mins

1 week he runs 105x3 = 315 minutes

To make it easier, convert it all to minutes

21 hours = 1260 minutes

1260 /315 = 4

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
