Answer:
50 student
350 adult
Step-by-step explanation:
x=# student tickets
y=#adult tickets
x+y=400 2x+3y=1050
x=400-y 2(400-y)+3y=1050
800-2y+3y=1050
y=350
x=400-350
x=50
Question 1:
Let's convert 9 feet into inches. To do that, we multiply the number of feet by 12.
9*12 = 108
Now, create a ratio using 108 and 6. We get the following
6 : 108
This can be simplified by dividing both sides by 6
1 : 18
Question 2:
Add 5 and 2 (the components of the ratio). You get 7.
Divide 175 by 7. You get 25.
Now multiply 25 with 5, the red-brick part of the ratio.
5 * 25 = 125.
125 red bricks were used. Have an awesome day! :)
