Answer:
see explanation
Step-by-step explanation:
since X is the midpoint of PQ , then
PX = QX ( substitute values )
4x + 15 = 7x + 6 ( subtract 4x from both sides )
15 = 3x + 6 ( subtract 6 from both sides )
9 = 3x ( divide both sides by 3 )
3 = x
Then
PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27
XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27
PQ = PX + XQ = 27 + 27 = 54

Answer:
(g+5)x(g-3)
Step-by-step explanation:
Edmentum/PLATO answer:
Rewrite the expression:
g+1/g^2+5g-3g-15 + g+3/g+5
Factor out g from expression:
g+1/gx(g+5)-3g-15 + g+3/g+5
Factor out g+5:
g+1/(g+5)x(g-3) + g+3/g+5
Least common denominator: (g+5)x(g-3)
35+70 = 105
180-105 = 75
x = 75
Answer:
Amy is (21.6 - 14.4) 7.2 km/hr faster than Bill.
Distance = speed / time
Amy's speed
40 minutes = 40/60 = 2/3 hours
14.4 = speed / 2/3
Speed = 14.4 * 3/2 = 21.6 km/ hr
Bill speed
60 minutes = 1 hour
Speed = 14.4 km / hr.
