Answer:
The number of wreaths Alaina sells is 9 .
Step-by-step explanation:
As given
Alaina is selling wreaths and poinsettias for her chorus fundraiser.
Wreaths cost $27 each poinsettia cost $20 each.
If she sold 15 poinsettias and made $543.
Let us assume that the number of wreaths Alaina sells = x
As the number of poinsettias Alaina sells = 15
Than the equation becomes
27x + 15 × 20 = 543
27x + 300 = 543
27x = 543 - 300
27x = 243
x = 9
Therefore the number of wreaths Alaina sells is 9 .
Answer:
29 in ^3
Step-by-step explanation:
6 sides
2 of which are smaller than the other 4.
12 x 1/2 x 4 = 4 longer sides
5 x 1/4 x 4 = 2 shorter sides
12 x 1/2 = 6
6 x 4 = 24
5 x 1/4 = 1.25
1.25 x 4 = 5
5 + 24 = 29
29 in ^3
-4p+(-2)+2p+3 simplified is:
