The four sides to create the square
Let's define the following variables first.
A = number of tickets sold for adults
C = number of tickets sold for children
From the question, we can say that or form the following equations:
1. A + C = 790 tickets
2. $7A + $4C = $4, 390
The first equation can also be written as A = 790 - C. We can use this equation and replace "A" in the second equation.

From that, we can solve "C" by solving the equation formed above.

Therefore, 380 tickets for children were sold.
Since there are 790 tickets in total that are sold and 380 tickets for children were sold, we can say that 410 tickets for adult was sold.
Answer:
730 miles
Step-by-step explanation:
7 hours * 40 mph=280 miles
9 hours * 50 mph= 450 miles
280+450=730 miles.
Hope this helps!
x/5(10-11) Remember PEMDAS and remember to isolate the variable;)
1. x/5(10-11) =2 (subtract)
2. x/5 * -1 =2 (add +1 to each side)
3. x/5= 3 (multiply both sides by five)
4. x=15
