Okay I am horrrrible at math and I'm home schooled I've been working on the same maj assignment for about 4 months now >_< I know it's a long time I just can't seem to figure out these problems anymore and I'm teaching myself...
Thanks!!
1. Dan can shovel the snow from his driveway in 45 min. His wife, Janice, can shovel the driveway in 1 1/4 hours. What is the ratio of Dan's shoveling time to Janice's shoveling time?
2. The americans school recycles its paper. At the end of the three weeks, the scho has accumulated 2100 pounds of paper. What is the school's rate of paper collection in pounds per day? (the school is closed on Saturdays and sundays)
3. Jim and bob are panning for gold in Leadville, Colorado. The ratio of gold found by Jim to gold by bob is 4:7. If the two men together find a total of 55 pieces of gold how many pieces of gold each man found?
Use the 5 step method! Make sure your answer was found out in a algebra solution!
Solve the proportions below to solve for variables CHECK!
4. A-6 over a+15 = 2a over 2a+6
Please show a check!!!

Covert 1 1/4 to minutes = 75minutes
45:75
9:15
3:5 <--- final anwser

3 weeks = 7*3= 21days - weekends 2*3= 6days
21-6 =15
15 days collecting paper
2100 pounds is collected over 15 which = 2100/15 = amount of pounds per day

Use the 5 step method! Make sure your answer was found out in a algebra solution!
Step one: 4+7 = 11 (11 parts)
Step two: 55/11=5 (each part = 5)
Step three: 4*5 = jims findings = 20
Step four: 7*5 =bobs findings = 35
Step five: (put into algebraic equations). 20:35
Solve the proportions below to solve for variables CHECK!
4. A-6 over a+15 = 2a over 2a+6
A-6/A+15=2*A/2A+6
A-6*A+15= A^2 -90
A^2 -90= 6
A^2=96
A= Square root of 96
A=9.8
Hope this helps you :s

1. 3/5
2.140 pounds per day
3. Jim: 20
Bob: 35
4. I'm a little confused by how you have it written so I don't know!
Hope that helps!
