Mary baked 21 cookies on saturday and twice that many on sunday for a school fundraiser. 4 cookies fell on the ground and had to
be thrown out. if she packaged 3 cookies to a bag, how many cookies were left over?
1 answer:
21+21= 42 cookies minus 4 = 38 cookies
38/3= 12.66(round down to 12)
She made 12 bags with 3 in Each which is 36, so 2 were left over

4(2 - x) > -2x - 3(4x + 1)
8 - 4x > -2x - 12x - 3
-4x + 2x + 12x > -3 - 8
10x > -11
x > -11/10
x > -1.1
Therefore, x = 0 and x = 10 zre solutions to the inequality.
4.572 kilometers is the answer.
Answer:
25.56 is the surface area of the pool.
Hope this helps! :)
