Answer:
Step-by-step explanation:
~First we have to write our two equations that are:
1. 8x+5y=$495(becoz the no. of adult tickets is unknown and children is unknown we use variables instead and multiplying them with the amount of money for each gives us 495)
2. x+y=75( No. of adult tickets and children altogether gives us 75)
~Use the substitution method by using any of the equations and putting the variable you want as the subject and then putting its values in the next equation:
x+y=75
x=75-y
~Substitute to find y(no. of children’s ticket)
8x+5y=495
8(75-y)+5y=495
600-8y+5y=495
-8y+5y=495-600
-3y=-105
y=-105/-3
y=35
Therefore, the no. of children tickets is 35.
~Substituting y in the substitution equation(x=75-y):
x=75-35
x=40
Therefor no. of tickets sold to adults is 40.
~Final answers:
Adults=40
Children=35

Step-by-step explanation:
Jada makes sparking juice by mixing 2 cups of sparkling water with every 3 cups of apple juice.How much sparkling water does Jada need if she uses 15 cups of apple juice?
Answer = 10
Explanation:
Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice
2 : 3
Thus also means:
2/3 = x/15
Solve for x:
x = 10
-------------------------------------------------------------------------------------------------------------
How much apple juice does Jada need if she uses 6 cups of sparkling water?
Answer = 9
Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice
2:3
Also means:
2/3 = 6/x
Solve for x
x = 9
-------------------------------------------------------------------------------------------------------------
Let S represent the number of cups of sparkling water and J represent the number of cups of apple juice. Write an equation that shows how S and J are related. Use your answers from the previous question to assist you with your answer.
Answer = j = 3/2 ⋅ s

Answer:
1.15
Step-by-step explanation:
tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
