Answer:
Step-by-step explanation:
<u>Mark</u>
- Initial amount - $200
- Earning - $20*j
- Saving is: S = 20j + 200
<u>Ryan</u>
- Initial amount - $350
- Earning - $15*j
- Saving is: S = 15j + 350
<u>If they get same saving, then the equations will be equal:</u>
- 20j + 200 = 15j + 350
- 20j - 15j = 350 - 200
- 5j = 150
- j = 150/5
- j = 30
The answer is 30 mowing jobs
9982 is the correct answer
Put it all into the same measurement unit -
Kim: 48,600 seconds. (13.5*60=810, 810*60=48600)
Javis: 50,700 seconds. (845*60=50,700)
Monica: 49,500 seconds.
Kim finished the book first.
You would simply have to plug in, or substitute, the given values in the equations.
So, H=-5, W=2 and the problem is 4h-3w
To plug them in, your new equation would be 4(-5)-3(2) and simplify. So it becomes -20-6 which = -26.
And -26 would be your answer.
