Answer: the price of each CD before tax is $14.9
Step-by-step explanation:
Let x represent the price of each CD before tax.
Abdul bought 3 CDs that were each the same price. It means that the total cost of the 3 CDs before tax is $3x.
Including sales tax, he paid a total of $47.40. Of that total, $2.70 was tax. It means that
3x + 2.7 = 47.4
3x = 47.4 - 2.7
3x = 44.7
x = 44.7/3
x = 14.9
the price of each CD before tax is $14.9
The answer to your question is the first option, which includes the points (3,6) and (5,10).
We know that this is the answer because the two numbers, if set up in fractional form, are proportional.
Additionally, the two points like on the same line in the graph.
Hope this helps!!
Answer:
10
Step-by-step explanation:
First, factorize the number 3,240:
So,
Now consider the fraction
If k = 10, then
is a square number.
For all k < 10, the fraction tex]\dfrac{3,240}{k}[/tex] is not a square number (this follows from factorization).
Or you can simply check the values of the fraction for all k < 10:
- k = 1,
is not a square number; - k = 2,
is not a square number; - k = 3,
is not a square number; - k = 4,
is not a square number; - k = 5,
is not a square number; - k = 6,
is not a square number; - k = 7,
is not a square number; - k = 8,
is not a square number; - k = 9,
is not a square number.
5t/13 = -9
5t = -9 * 13
5t = -117
t = -117/5
