Answer: 18.84
Step-by-step explanation:
This is a multi step problem. For this we do system of equations.
2.5x + 7y = 82.50
X+y = 24
To do the elimination method we have to make the y values equals to each other so we multiply the x+y=24 equation by 7
7x +7y = 168
-
2.5x + 7y = 82.50
———————————-
4.5x = 85.50

4.5. 4.5
X = 19

The midpoint is exactly in the middle
meaning
VW = WX
3x+7 = x + 25
solve from x
3x + 7 = x + 25
subtract 7 from both sides
3x = x + 18
subtract x from both sides
2x = 18
divide both sides by 2
x = 9
Now we have x = 9 but we aren't done.
plug what we found into the expressions
3x + 7
3(9) + 7
27 + 7
34
x + 25
9 + 25
34
34 + 34
68
The length of VX is 68.
Or option D.) 68
