Answer:
5
Step-by-step explanation:
3(3x+7) = 3x+51
9x + 21 =3x+51 ; cuz 3 times 3 is 9 and 3 times 7 is 21
subtract 21 so 21 - 21 = 0 and 51 - 21 = 30 so
9x= 3x+30
Then subtract 3! 9-3x and 30 - 3x
You will get 6x = 30
Next you will divide by 6x
Lastly you will get 5! So your answer is 5, sorry it's a little messy but I hope this helps!
Answer:
$18,112.45 (nearest cent)
Step-by-step explanation:
Let y = value of the boat
Let x = the number of years
If the boat depreciates in value by 15% each year, then each year that goes by, it is worth 85% of the previous year's value (since 100 - 15 = 85)
85% = 85/100 = 0.85
Therefore, the equation is: ![y = 92000 \times 0.85^x](https://tex.z-dn.net/?f=y%20%3D%2092000%20%5Ctimes%200.85%5Ex)
So, when x = 10:
![\implies y = 92000 \times 0.85^{10}=18112.45](https://tex.z-dn.net/?f=%5Cimplies%20y%20%3D%2092000%20%5Ctimes%200.85%5E%7B10%7D%3D18112.45)
