-8-5=2 i think this is right i could b wrong
Answer:
Step-by-step explanation:
-37-6=7-21 Step 2 is wrong
It should be
-3x - 6 = 7-2x
-3x + 2x = 7 + 6
-x = 13
x = -13
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.
