Answer:
7/12 3/4 5/6
Step-by-step explanation:
1.8 - 0.2x = -1.6 Subtract 1.8 on both sides
1.8 - 1.8 - 0.2x = -1.6 - 1.8
-0.2x = -3.4 Divide -0.2 on both sides

x = 17
Answer:
12
Step-by-step explanation:
These are similar triangles, so the ratio of their sides is the same for each side.
AB = 8 and BD = 10
So, the ratio is 8:10 or 4:5
Because the triangles are similar....
The ratio of AC:CE is also 4:5
12:15 = 4:5
So, 12 is the answer!
Take logs of both sides:-
ln 625^x = ln 5
x * ln 0.625 = ln 5
x = ln 5 / ln 625
x = 0.25 answer
