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:
One solution
Step-by-step explanation:
Answer:
2x+10
Step-by-step explanation: First you have to distribute the two, into the parenthesis. Which brings it to 2x+6+4 and then you just combine the 6 and 4 making it a ten so 2x+10
Answer:
The answer to your question is: d) 0.46x10^-4
Step-by-step explanation:
(1.15x10⁻⁷) / (2.5x10⁻³)
First, divide 1.15 by 2.5 1.15 / 2.5 = 0.46
Second, subtract the power -7 - (-3) = -7 + 3 = -4
Finally, express the number 0.46 x 10⁻⁴
a) 4.6x10^-10
b) 0.46x10^-3
c) 4.6x10^-3
d) 0.46x10^-4
Answer:
4,020
Step-by-step explanation:
To find the volume of a rectangular object, measure the length, width and height. Multiply the length times the width and multiply the result by the height. The result is the volume.
