The first step to determine the function is to find the total cost of the auction. This is done by adding all the prizes and the cost of the food.
The total cost of the auction is $900. Since the cost of 50 tickets should be able to cover the cost, we need to divide the total cost by the number of tickets to determine the cost of each ticket.
Each ticket must be sold as $18. The whole function is:
Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.
Let the three numbers be x, y and z. Then x+y+z=75.
z = 2x. y = x - 9.
Eliminate y and z by substitution: x + (x - 9) + (2x) = 75
Then 4x = 75 + 9, or 4x = 84. x = 21, y = 21 - 9 = 12, and z = 2(21) = 42.
Check: Do 21, 12 and 42 add up to 75?
Answer:
C
Step-by-step explanation:
2x+3x Have the same variable. Therefore they both have like terms
Cubes and then three dimensional
