2m + n = 2
3m - 2n = 3

m = 1   n = 0

Step-by-step explanation:

(2m + n = 2)2              You need to cancel out one of the variable, so I chose n

3m - 2n = 3

3m - 2n = 3            

4m + 2n = 4              Add the two equations together

7m = 7                       Divide both sides by 7

m = 1

Plug 1 in for m into one equation

2(1) + n = 2

2 + n = 2        

-2       -2                     Subtract 2 from both sides

n = 0

Check this with the other equation to make sure it is the same answer

3(1) -2n = 3

3 - 2n = 3

-3        - 3                    Subtract 3 from both sides

-2n = 0                        Divide both sides by -2

n = 0                          

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

5/20 so 25%
