Answer:
27
Step-by-step explanation:
If Fiona's age is x, Dan and Gavyn's ages respectively are x + 8 and x - 9. We can write:
x + x + 8 + x - 9 = 56
3x - 1 = 56
3x = 57
x = 19
The eldest is Dan (because x + 8 > x and x + 8 > x - 9). His age is x + 8 = 19 + 8 = 27.

Step-by-step explanation:
Collect all variables in one side and numbers on the other side
7w-2w=-3-12
5w=-15
W=-15/5=-3
Answer:
Step-by-step explanation:
<u>Since T is midpoint, ST and TU have equal length:</u>
<u>Substitute the values and solve for x:</u>
- 6x - 8 = 4x + 9
- 6x - 4x = 9 + 8
- 2x = 17
- x = 17/2
- x = 8.5
