Answer:
(6.2, 4.5)
Step-by-step explanation:
That point (P) will be the weighted average of the end points, where each weight is the proportion of the segment at the end farthest from the point:
P = (3A +1B)/(3+1)
= (3·7.5 +2.3, 3·4.2 +5.4)/4
= (24.8, 18)/4
= (6.2, 4.5)
Here is my answer. I left the latter question in a. as I don't actually know the answer. Anyway, I hope this is helpful although not complete.
x+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
