Answer:
45/7
Step-by-step explanation:
ok lets first find the total sum. there are 5 numbers so 13*5=65
2x+0+5x+11+9=65
7x=45
x=45/7 or 6.42857143
For this case, the equation modeling the problem is given by:
Where,
x: number of miles
y: total cost
For 12,000 miles we have:
Therefore, to handle 12,000 miles, the cost will be $ 7440.
Answer:
it costs 7440 $ to drive a car 12,000 miles in 2012.
2 1/4 - 3/4 = 3/2
(2x4=8 +1 is 9. So, 9/4 - 3/4 is also 6/4)
Sum = add
3/4 + 5/6 = 19/12
Thus, its 3/2 ÷ 19/12
(remember keep change flip for this - KFC)
3/2 ÷ 19/12
3/2 x 12/19 = 36/38
Simplify to get 18/19
Answer : 18/19
Hope this helps!
Answer:
B) y=5x-17
Step-by-step explanation:
I got this answer, by first making sure it was parallel to y=5x+7. Which was easy because the only thing they need to be parallel is the same slope, in this case was 5. Next I pluged in (4,3) to y=5x-17. I substituted 4 into x and got 20. Then I substituted 3 into y. Since 20-17 is equal to 3, then B. is your answer.
