1. 2/4, 3/6, 4/8
2. 1,2,3,5,7,11,13,17,19
3. 1/3 + 2/7 = 13/21, 3/5 - 2/9 = 17/45
Answer:
-5 is the value of a, 4 × -5 = -20
0.15 x 40 = 6 and 40+6 = 46
So you can drive below 46 miles per hour without getting a ticket
Hope this helps!
Answer: Can you upload a picture of the question?
Step-by-step explanation:
Let the value of the car be represented by V and the amount of years by y.
This gives us the following formula:
V = 25,635 - 3000y
(This is because we start with a value of $25,635 and the value decreases by $3,000 every year 'y')
Now, we want to know when the car is worth $3,135, so we know V = 3,135
Now we can make up our equation:
25,365 - 3,000y = 3,135
Collecting terms gives us:
-3,000y = -22,500
Finally we divide by -3,000 to find 'y'
y = -22,500 / -3,000 = 7.5
Hence, the car will be worth $3,135 after 7.5 years.
