Answer:
y=7
Step-by-step explanation:
x+y=12
x=5
12-5=7
Your equation should be
$4(40 tickets) + $5(X) = $400
160 +5x = 400
-160 -160
0 5x = 340
divide both sides by 5
5x/5 = 340/5
x = 68
so they need to sell 68 tickets at the door.
4(40) + 5(68) = 400
160 + 340 + 400
400 + 400
Answer:

Step-by-step explanation:
1. To find the answer, add up all the marbles.
4+5+7= 16
2. Because 16 is the total number of outcomes, it will be the denominator.

3. Because 5 is the number of desireable outcomes, it will be the numerator.

(Note: the <u>decimal equivalence</u> is 0.3125).
(Note: the <u>ratio equivalence</u> is 5:16).
(Note: the <u>percent equivalence</u> is 31.25%).
