Step-by-step explanation:
Wendy
-20 = x/2 + 7
-20 -7 = x/2 + 7 -7
-27 = x/2
-54 = x
x = -54
because it's math rule
(8,12)(14,3)
Use midpoint formula
(X1+x2/2, y1+y2/2)
Substitute with your points
(8+14/2, 12+3/2)
Solve each
(22/2,15/2)
Cancel common factor 2
(2×(4+7)/2(1),15/2)
Simplify
(4+7/1,15/2)
This is your midpoint
(11, 15/2)
well what i got was:
the exact form: 233/28
decimal form: 7.96428571...
mixed number form: 7 27/28
not sure if this is right at all but i hope it helps at least a little
Answer:
After 4 hours
Step-by-step explanation:
4h = 2(2) + 6(h - 2)

4h = 6h - 8
2h = 8
h = 4
