Answer:
660 balloons and 14 packages
Step-by-step explanation:
first let's find out how many balloons we'll need for all the rooms together.
220x3=660
Now let's see how many packs of balloons we need.
660/50=13.2, since it isn't a whole number you'll need 14 packs and some will be left over.
I hope I can help and this isn't confusing!
This is your personal answer
2( x - 6) <= 28
x - 6 <= 14
x <= 20
90^2+120^2=c^2
180+240=c^2
420=c^2

Answer:
x = -8 and x = -4.
Step-by-step explanation:
1/(x + 3) = (x + 10)/(x - 2)
1 * (x - 2) = (x + 10) * (x + 3)
x - 2 = x^2 + 3x + 10x + 30
0 = x^2 + 13x + 30 - x + 2
0 = x^2 + 12x + 32
0 = (x + 8) * (x + 4)
1. x = -8
2. x = -4
The correct result would be x = -8 and x = -4.

Answer:
The area is 84. The missing side is 7.
Step-by-step explanation:
Okay so perimeter = length+length+width+width right? If 12 is the length, then 12+12=24, which is the length part of perimeter. 38-24=14 and 14/2=7. The missing side is 7 because 12+12+7+7=38 and the area is 84 because 12x7=84. Good luck!
