Answer:
10
Step-by-step explanation:
By using intersecting chord theorem:
NH.HT=MH.HY
(x+20)*8=12*20
x+20=12*20/8
x+20=240/8
x+20=30
x=30-20
x=10
Answer: 4(7-u)
Step-by-step explanation:
In order to factor, you have to find the GCF (Greatest Common Factor)
28:1, 28, 2, 14, 4, 7
4:1, 4, 2
The greatest common factor here is 4.
You can factor out 4 from this equation, therefore making it 4(7-u)
If depreciation is 7.25% per year, then the common factor is (1-0.0725), or 0.9275.
Thus, the car's value after 5 years will be:
V = $28000(0.9275)^5 = $28000(0.6864) = $19218.86, or (to the nearest dollar) $19218 (answer)

First, subtract '11' from each side.

Second, subtract '29 - 11' to get '18'.

Third, since we are solving for f, we have to get it by itself. Multiply each side by 'f'.

Fourth, once again, we need to get 'f' alone. Divide both sides by 18.

Fifth, now that we have 'f' by itself, we can simplify the current fraction. To do so, we need to start off with listing the factors of 4 and 18 and find the greatest common factor (GCF).
Factors of 4: 1, 2, 4
Factors of 18: 1, 2, 3, 6, 9, 18
Out of the listed factors, 1 and 2 are the common factors, and since 2 is the highest number out of them, it is considered the greatest common factor. The GCF is 2.
Sixth, divide the numerator and denominator by the GCF (2).

Seventh, we can now rewrite our fraction in simplest form and switch sides.
