Answer:
Each piece is 2 ft and 8 inches long.
Explanation:
12 inches are in a foot, so 12 times 8 equals 96.You then divide 96 by 3 which is 32.So 32 inches is 12in+12in+8in= 2feet 8 inches
System of Equations
For the problem to solve we'll use the following variables:
x = number of the early bird tickets sold
y = number of the regular tickets sold
Haley sold a total of 20 tickets, thus:
x + y = 20 [1]
Early bird tickets cost $10 and regular tickets cost $15, thus the total money collected is:
10x + 15y = 225
Dividing by 5:
2x + 3y = 45 [2]
We have to solve the system of equations [1] and [2].
Multiply [1] by -2:
-2x - 2y = -40 [3]
Add [3] to [2]:
-2x - 2y +2x + 3y = -40 + 45
Simplifying:
y = 5
Substituting in [1]:
x + 5 = 20
Subtracting 5:
x = 20 - 5
x = 15
Solution: Hayley sold 15 early bird tickets and 5 regular-priced tickets
The order pair solution is (15,5)

Answer:
Step-by-step explanation: Sub -3 into where all the u’s are. So it would be
(-3)^2 - 2(-3) + 4
Which would equal 19
