Answer
t = 3n
Step-by-step explanation:
n and t are proportional so you know they will be on the opposite ends of the equal sign. Then you know that the items are purchased at the constant price of $3. That means you do the number of items times 3 to get the total cost.
Given:
2002 sold 1000 paperback books and 1500 hardback books for a total of 2,500 books.
2003 sold 15% more paperback books and 5% more hardback books.
1000 x 1.15 = 1,150 paperbacks
1500 x 1.05 = 1,575 hardbacks
1150 + 1575 = 2,725
2,725 - 2,500 = 225
225 / 2,500 = 0.09
0.09 x 100% = 9% choice C
7) A
8) C
9) B
I’m not certain but I hope this helps you...sorry if I got it wrong!!
Answer:
x=1,13
Step-by-step explanation:
(x – 7)^2 = 36
Take the square root of each side
sqrt((x – 7)^2) = sqrt(36)
x-7 = ±6
x-7 = 6 x-7 =-6
Add 7 to all sides
x-7+7 = 6+7 x-7+7 = -6+7
x = 13 x=1
Answer:
180
