Question: I have four questions that I really need help with. I am a really good straight A student, but my teacher didn't cover this as much. Write and Solve an equation for each situation: Marla begins walking at 3mi/h toward the library. Her friend meets her at the halfway point and drives her the rest of the way to the library. The distance to the library is 4 miles. How many hours did Marla walk? Fred begins walking toward John's house at 3 mi/h. John leaves his house at the same time and walks toward Fred's house on the same path at a rate of 2mi/h. How long will it be before they meet if the distance between the house is 4 miles? A train leaves the station at 6:00 P.M. traveling west at 80mi/h. On a parallel track, a second train leaves the station 3 hours later traveling west at 100mi/h. At what time will the second train catch up with the first? It takes 1 hour longer to fly to St. Paul at 200 mi/h than it does to return at 250 mi/h. How far away is St. Paul? If you could answer all, or even one of them, that would help a ton... Thanks

I think the complete statement of the problem is (5x-1)+(-3x-1) = 0 The rule is to combine like terms. Note that we have a term x plus some constants in the equation. Let's combine x's first 5x+ (-3x) = 2x Now combine constants -1 + (-1) = -2 So we have 2x - 2 = 0 Now we need to get x to stand alone, so we add 2 to each side of the equation 2x -2 +2 = 0 + 2 or 2x = 2 Now we divide by 2 and get x = 1 Let's check (5x1 -1) + (-3x1 -1) = (5 -1) + (-3 -1) = (4) + (-4) = 0 All's well and good

(5x-1)+(3x-1) ...bring equation down 5x-1+3x-1.....combine like terms 5x+3x=8x 8x-1-1...combine like terms -1-1=-2 8x-2 I think that's right depending on what your directions say do. If you have to find x the answer is. 0.25 if not its 8x-2

Sorry, due to lack of time, I can onl answer the first. We know the distance from wherever Marla started from is 4 miles, and she stops halfway to hitch a ride with her friend. That stop point is at the 2 mile point. So in how long does it take for Marla to walk 2 miles at 3miles/hr? Well if it was 3 miles, it would've taken her an hour. But instead, it was 2, meaning it would've taken 2/3 the time to walk an hour, also meaning 2/3 of an hour. 2/3 of an hour, would be 40 minutes

The mean is the average. I can't tell if the 1. is part of the problem, so I'll have to solve it two ways. First, without. (4.8 + 1.6 + 5.2 + x)/4 = 3.7 Multiply both sides by 4 (4.8 + 1.6 + 5.2 + x) = 14.8 Add like terms 11.6 + x = 14.8 Subtract 11.6 x = 3.2 Now with: (1. + 4.8 + 1.6 + 5.2 + x)/5 = 3.7 Multiply both by 5 1. + 4.8 + 1.6 + 5.2 + x = 18.5 Combine like terms 12.6 + x = 18.5 subtract 12.6 x = 5.9

What you want to do is add all those numbers and divide it by 4 (the number of numbers) and set it equal to 3.7 So: (4.8+1.6+5.2+x) divided by 4 = 3.7 Multiply both sides by 4 to get (4.8+1.6+5.2+x)= 14.8 Then 11.6 + x = 14.8 Subtract 11.6 from both sides and you get x = 3.2 Hope this helps! (:
