Hmmmm is not very clear if the 25% is just 25% of the original price, or of the reduced price, but let's assume is of the reduced price.
say the original price is "x", 20% off that, means the sale price is 80% of the original price, or (80/100) * x, or 0.8x.
then Linz shows up on the last day, and she's got 25% off from that price plus a beanie baby and a free garden hose.
so if the price is reduced by 25%, then the sale price is just 75% of whatever it was, but it was already reduced to 0.8x, what is 75% of 0.8x?
(75/100) * 0.8x, or 0.75 * 0.8x, which is 0.6x, now 0.6 * 100 is 60 to change it to percentage format, or 60% overall percentage reduction from the original price.
C. y - 3 = 2/3(x-3)
Nothing much to do here except examine each equation and plug in the numbers to see if it's true.
a. y + 3 = 3/2(x+3)
Try 3,3
3 + 3 = 3/2(3+3)
6 = 3/2(6). And no need to go further, it's obviously not equal.
b. y - 3 = 3/2(x-3)
Try 3,3
3 - 3 = 3/2(3-3)
0 = 3/2(0). OK. Let's try 6,5
5 - 3 = 3/2(6-3)
2 = 3/2(3)
2 = 9/2 And it's not true, so check the next one.
c. y - 3 = 2/3(x-3)
Try 3,3
3 - 3 = 2/3(3-3)
0 = 0. Check 6,5
5 - 3 = 2/3(6-3)
2 = 2/3(3)
2 = 2. Good. Both sample points work. This is the correct answer.
Just to be sure, let's check the next option
d. y + 3 = 2/3(x+3)
Try 3,3
3 + 3 = 2/3(3+3)
6 = 2/3(6). And doesn't match.
Answer:
9a+12
Step-by-step explanation:
The perimeter is the sum of the side lengths, so is ...
6a + a + 4 + 8 + 2a
= a(6 +1 +2) + (4 +8)
= 9a +12
Answer: $25,500
Step-by-step explanation:
15/100 = 4500/x , we use this proportion to find out how much the entore book deal was. When you multiply 4500 x 100 and divide by 15, it gives you an answer of 30,000. 30,000 is the value of the book deal. The agent gets 15% but the entire deal would be worth 100%. We subtract 15% from 100% to get 85%. 85% is what the author will receive. 85% of 30,000 is $25,500. We find the answer by multiplying 30,000 by 0.15. 0.15 is the decimal equivalent of 15.
