PLZ HELP 5 3/5 + 3/4 + 2 1/2

8 17/20

Step-by-step explanation:

1. (make all the fraction have the same denominator)the denominator is 20...

3/5= 12/20  3/4=15/20 1/2=10/20

2. (add) 5 12/20 + 15/20 + 2 10/20 = 7 37/20

3. (there is an improper fraction) u have to subtract 37-20...37-20=17 now add 1 hole number to the faction and put 17 over the 20 like this...17/20...now ur answer will be 8 17/20

1. The system does has one solution.
2. The systems doesn't graph as parallel lines.
3. Both lines do not  have a same slope.
4. Both lines do have a y - intercept.
5. The equations don't graph as a same line.
6. The solution is the intersections of two lines.

2y = x + 10
 2         2
 y = 0.5x + 5

3y = 3x + 15
 3          3
  y = x + 5

  0.5x + 5 = x + 5
- 0.5x   - 0.5x
             5 = 0.5x + 5
           - 5             - 5
             0 = 0.5x
           0.5    0.5
             0 = x
             y = x + 5
             y = 0 + 5
             y = 5
       (x, y) = (0, 5)
