You will have to write a system of equations.
Let x represent the number of child tickets.
Let y represent the number of adult tickets.
Your two equations will be:
5.60x + 9.10y = 1045.10
x + y = 136
This is going to be solved using the substitution method.
x + y = 136
x = 136 - y
Substitute x for 136 - y in the other equation.
5.60x + 9.10y = 1045.10
5.60(136 - y) + 9.10y = 1045.10
Distribute the outside terms through the terms inside the parenthesis.
761.60 - 5.60y + 9.10y = 1045.10
Combine like terms.
761.60 + 3.5y = 1045.10
Subtract 761.60 from both sides to get 3.5y by itself.
3.5y = 283.5
To get y by itself, divide both sides by 3.5.
y = 81
81 adult tickets were sold that day.
Answer:
width = 14.5 feet
Step-by-step explanation:
Area = length * width
333.5 = 23 * x divide both sides by 23
14.5 = x
Answer:
x = 127 degrees
Step-by-step explanation:
The sum of the interior angles is (n-2)180, so in this case it would be
(6-2)180
(4)180
720
Then you can substitute the given angle measurements to get the equation:
112+133+128+100+120+x = 720
593+x = 720
x = 127
The measure of the interior angle at vertex C is D. 144.
<h3>How to calculate the angle?</h3>
Based on the information given, the angle will be calculated thus:
8x + 8x + 8x + 3x + 3x = (5 - 2) × 180
30x = 540
Divide both side by 30
30x/30 = 540/30
x = 18
Therefore, at vertex C, we have 8x. This will be:
= 8x
= 8 × 18
= 144
