Answer:
3 foil, 6 latex
Step-by-step explanation:
First, you can put all of these words words into equations. We know there are 162 ballons (18 players)(9 bouquets). So we can put it in the equation
x + y = 162
Since each foil balloon costs $1.92 and each Latex balloon costs $.19 and they all cost $124.20. We can put it in an equation:
.19x + 1.92y = 124.20
You then get the systems of equations:
x + y = 162
.19x + 1.92y = 124.20
solving for the equation, you get x = 54 and y = 108. BUT, you have to be careful. The problem said "How many of each type of balloon did each <em>bouquet</em> include?" So we need to divide both by 18 for the player because each player recieved on bouquet.
Answer: x=2 (C)

There are 100 years in a century
Answer:
2/13 or 0.15 , 1/4 and 5 /18 or 0.28
Step-by-step explanation:
20/26 ÷ 5 =?
10/13 ÷ 5 = 2/13 or 0.15
28/56 ÷ 2 =?
1/2 ÷ 2 = 1/4
75/90 ÷ 3 =?
5/6 ÷ 3 =5 /18 or 0.28
The 3 inside angles of a triangle equal 180.
Add the 3 angles together to equal 180:
X + (5x-20) + 4x = 180
Simplify the left side by adding like terms:
10x-20 = 180
Add 20 to each side:
10x = 200
Divide both sides by 10:
x = 20
Angle A = x = 20
Angle B = 4X = 4(20) = 80
Angle C = 5x-20 = 5(20) -20 = 100-20 = 80
