Answer:
5x cars
Step-by-step explanation:
(# of cars washed) = (# cars washed per day)(# of days)
= (x/day) * (5 days) = 5x
cars
If you burned the same number of calories every minute while you kept biking for 45 minutes, and burned a total of 560 calories, then the number of calories burned per minute is 560/45=112/9
First, the mark down 15% would make the value 85% of the original, so doing 15.99*0.85 gives you 13.59. Then take that and multiply that by 0.5, because of the half price, to get a final price of $6.79
Question:
What is the common ratio between successive terms in the sequence?
27, 9, 3, 1
Answer:
common ratio = 
Step-by-step explanation:
In a geometric progression, the common ratio, r, is the ratio of a term in the sequence to a preceding term in that same sequence. In other words, the common ratio is found by dividing a term by the term just before it. For example, if the geometric sequence is:
a, b, c, d...
The common ratio is found by any of the following;
r =
----------(i)
r =
-----------(ii)
r =
------------(iii)
Any of equations (i) through (iii) will give the common ratio of the sequence.
============================================================
Now, from the question, the given sequence is;
27, 9, 3, 1
To get the common ratio, just divide the second term (9) by the first term (27) i.e
r =
= 
OR
You can also divide the third term (3) by the second term (9). i.e
r =
= 
OR
You can choose to divide the fourth term (1) by the third term (3). i.e
r = 
Which ever adjacent terms you choose gives you the same result. Therefore, the common ratio of the given sequence is 
Y = 3x - 1
The slope is 3, y goes up 3 for every increase in x
The intercept point of the Y axis is -1
