Answer 1

Answer: This is pretty simple once you think about it, you are probably just making it harder than it needs to be :) So, all you really have to do is plug in the numbers and see which statement is true. So, for the first one, you should work it out with me in the comments. Sorry lol I don't really like giving straight answers. lol

Answer 2

Answer: So the number choices you have are 27,17,14,13, and 37. So all you have to do is put one number in one box to finish the equation. So something plus 40 = something plus 10 :)

Answers

Answer:

Slope is 1/2

Y- intercept is -2

Step-by-step explanation:

Re-write the equation so that u have y = x/2 -4/2

Then simplify into y = 1/2x -2

Enter the value of n so the expression (-y + 5.3) + (7.2y-9) is equivalent to 6.2y + n.Please explain what and how you did it. I've seen other answers for the same question, but they do not make sense.

Answers

If you would like to find the value of n, you can calculate this using the following steps:

(- y + 5.3) + (7.2 * y - 9) = - y + 5.3 + 7.2 * y - 9 = - y + 7.2 * y + 5.3 - 9 = 6.2 * y - 3.7

6.2 * y - 3.7 = 6.2 * y + n
n = - 3.7

The correct result would be - 3.7.

Ray wants to buy an item worth $500. Which option is the most cost-effective? a. buying the item at list price with a coupon for $10 off
b. buying a membership for $35 and then getting the item at a 15% discount
c. buying the item online at a 10% discount and paying $4 extra for shipping

Answers

Answer:

Buying the item online at a 10% discount and paying $4 extra for shipping

Step-by-step explanation:

Ray wants to buy an item worth 500$ in the most cost-effective way. Let's study each of the 3 cases and see with option is the best.

In the first option, he'll buy the item at list price with a coupon for $10 off. So he'll buy it at 500-10 =$490.

In the second option, he'll buy a membership for $35 and then get the item at a 15% discount. With a 15% discount, the price of the item will be 500 - (500*0.15) = 500 - 75 = $425. And with the membership price, he'll pay a total of 425 + 35 = $460.

The third option is to buy the item online at a 10% discount and pay $4 for the shipping. At 10% discount, the price of the item will be 500 - (500*0.1) = 500 - 50 = $450. And with cost of the shipping, he'll pay a total of 450+4 = $454.

So if he chooses the first option, he'll pay $490. With the second, he'll pay $460. And finally with the third, he'll pay $454.

So the third option is the most cost-effective, buying the item at $454.

Hope this helps! :)
