Answer: x = 10

Explanation:

Proof that triangle CAB ~ EAD

Angle CAB = Angle EAD (same angle)

Angle ABC = Angle ADE = 90 degree

Thus, Triangle ABC ~ EAD (AA)

And CB/ED = 8/16 = 1/2

Which mean CB = (1/2)ED

That mean AB/AD also equal 1/2
Where AB = 1/2(AD)

We get:
x = 1/2(10 + x)
x = 5 + (1/2)x
x - (1/2)x = 5
(1/2)x = 5
x = 10

3 weeks

Step-by-step explanation:

To find the number of weeks, we have to equate the amount already saved and planned to save by both each week.

So we can write the expression as,

Let w be the number of weeks.

25 + 5w =16 + 8w

Grouping the terms as,

25 - 16 = 8w - 5w

9 = 3w

Dividing both sides by 3, we will get,

3w/3 = 9/3

w = 3

So number of weeks = 3
