Answer 1

38. -2.2

39. -1

Explanation:

38.

First let's count how far C is from F.

5 - (-4)=5 + 4 = 9

There are 9 spaces between C and F.

Let's find 9/5, which is 1.8

Because we're finding the distance from C to F, we add 1.8 to the value C.

-4 + 1.8 = -2.2

The point X in CF that is 1/5 of the distance from C to F is -2.2

Note: It's your judgement on whether or not your professor would want this in decimal form or rounded to -2. I'd keep it as -2.2 if you're not sure, because that is the correct answer.

39.

Now let's do the same thing with BD.

How far is B from D? 1 - (-5) = 1 + 5 = 6

What's (6*2)/3? 12/3 = 4

What's B + 4? -5 + 4 = -1

The point X on BD that is 2/3 of the distance from B to D. is -1

Answer 2

Answer: X=-2 1/5, X=-1

Explanation:

The distance from CF is 9 units, 1/5 that = 1 4/5, add that to -4 is -2 1/5.

The distance from BD is 6 units, 2/3 that =4, add that to -5 is -1.

Hope this helps!
