Answer:

Kevin is 6

Step-by-step explanation:

Let k represent Kevin's age now. Then Brendon's age now is (k-3). Two years ago the relationship of their ages was ...

k-2 = 4((k-3) -2)

k -2 = 4k -20 . . . . . eliminate parentheses, collect terms

3k = 18 . . . . . . . . . . add 20-k

k = 6 . . . . . . . . . . . . divide by 3

Kevin is 6 now.

Answer:

A: It has no solution

Step-by-step explanation:

2. 2/4z +3 = 2/4z + 5

3. 3 = 5 (No solution because 3 can never be equal to 5)

If DF+FE=DE, then point F is_________

Dima020 [189]

I believe the correct answer from the choices listed above is option A. If DF+FE=DE, then point F is A. a midpoint of DE (with line over). F is the endpoint of line segment DF and is the starting point of line DE thus it is in between line DE. Hope this answers the question.
