I am pretty sure your test score has to be an 86.
C+d=14
c-6=d
then you will plug c+6 in the first equation and you will get:
c+c-6=14
then you get
2c=20
c=10, so the cat is ten years old
the cat is 6 years older than the dog, so the dog is 4 years old
hope that helps :)
Answer:
10 years until the value of the car is 11000 dollars
Step-by-step explanation:
The value of the car after t years is modeled by the following equation:
In which V(0) is the initial value and r is the yearly depreciation ratio, as a decimal.
A new car is purchased for 21100 dollars.
This means that
The value of the car depreciates at 6% per year.
This means that . So
To the nearest year, how long will it be until the value of the car is 11000 dollars?
This is t when
To the nearest year
10 years until the value of the car is 11000 dollars
Answer:
X=10
Step-by-step explanation:
You can subtract 180 by 110 to get 70. Then you can do 8x+30+70=180
Add 30+70 to get 100
Subtract 100 to 180 to get 80.
8x=80
You divide 8 from both sides which leaves you with x=10.
