Answer:

Step-by-step explanation:

To solve, we can first cross multiply

28/63=4/x

28*x=63*4

28x=252

Since we are trying to find x(the missing number), we need to get x by itself. x is being multiplied by 28. To undo this, divide both sides by 28. This will cancel out 28 and leave x by itself.

28x/28=252/28

x=9

So, the missing number is 9

28/63=4/9

Answer:

3. 9n + 6 = 78

5. see below

Step-by-step explanation:

Let the number of adults be n. Each adult ticket costs $9, so the cost of n adult tickets is 9n. There is only one child, and a child's ticket is $6, so the cost of the child's ticket is 6. Adding the costs, you get 9n + 6. The total cost is $78, but the expression representing the total cost is 9n + 6, so 9n + 6 must equal 78. That is the equation.

9n + 6 = 78
