Answer:
4 pounds
Step-by-step explanation:
First, I subtracted the cost of the first pound from the final product (3.73 - 2.38) and I got 1.35. I then divided the 1.35 by .45 (the 45 cents) to figure out how many more pounds the package was from the initial 1 pounds. 1.35/.45 is 3, plus the 1 pound from the beginning makes 4 pounds in total.
Answer:
he needs to get a 91 to have a mean score of 90
Step-by-step explanation:
add up all the known scores to get 629
let 's' = lowest test score
(629 + s) ÷ 8 = 90 [we divide by 8 because there are 7 known and 1 unknown score)
cross-multiply to get:
629 + s = 720
s = 720-629
s = 91
Answer:
7(3 + 7)
Why:
7x3=21
7x7=49
The answer is all real numbers because -2x-6=-2x-6
Answer:
9 sides
Step-by-step explanation:
Given the sum of the interior angles = 1260°, then
180° (n - 2) = 1260 ( divide both sides by 180 )
n - 2 = 7 ( add 2 to both sides ), hence
n = 9
