1 answer:
aleksklad [387]3 years ago
4 0

Answer:

1/(k^2)

Step-by-step explanation:

Because the k's are above one another in the fraction format, using exponent rules you would subtract the top number exponents with the bottom number exponents (note do not do anything with the letter k). 5-7= -2, and k^-2 is the same as 1/(k^2).

Hope you have a great day and this helps! :)

Dylan bought 3 identical shirts online for a total cost of $71.83 including a flat rate of $7.99 for shipping. Drag numbers to c
Vesnalui [34]

Answer:

3s + 7.99 = 71.83

Step-by-step explanation:

Yeah, algebra sure confused me the first time I took it. I had a much more patient and engaging teacher the second time!

How would we find out in real life how much each shirt cost? We'd subtract 7.99 from 71.83 and divide the difference by 3, right??

Let's work that backward. Let's say a shirt cost $6. Three would cost $3(6), or $18. Since each shirt costs $s, our price for 3 shirts is $3s. We have to add shipping to get a total, which we are given. When writing an equation, we leave out labels like $ or meters or books or whatever.

a cd usally sells for 17.00 if the CD is 30% off and the sales tax is 8% what is the total price of the CD including tax
Ksenya-84 [330]

Answer:

$12.85

Step-by-step explanation:

First we need to find the sale price of the CD

Sale price = old price - old price * discount rate

                 = 17 - 17* .3

                 = 17 - 5.1

                 = 11.9

The sale price of the CD is 11.90

Now we need to find the tax

tax = sale price of cd * tax rate

      = 11.9 * .08

      = .95


The final cost of the CD is  sale price of CD plus the tax

Total cost = sale price of CD + tax

                 = 11.90 + .95

                    =12.85
