Answer:
Step-by-step explanation:
Let c represent the number of child tickets that were sold.
Let a represent the number of adult tickets that were sold.
The Celluloid Cinema sold 150 tickets to a movie. This means that
a + c = 150
A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, it means that
10.25a + 7.75c = 1470
Therefore, the system of equations that could be used to determine how many adult tickets, a, and how many child tickets c were sold is
1) a + c = 150
10.25a + 7.75c = 1470
Option 2 is incorrect because a + c is not equal to 1470
Option 3 is incorrect because rate of child and adult tickets were interchanged.
Option 4 is incorrect because a + c is not equal to 1470 and the rate of child and adult tickets were interchanged.
Answer:
n = m − a
Step-by-step explanation:
Given:
a = m - n
Where,
a = Actual cost an item
m = Original price
n = amount of coupon
Solve the formula for the amount of the coupon
a = m - n
Add n to both sides
a + n = m - n + n
a + n = m
Subtract a from both sides
a + n - a = m - a
n = m - a
Amount of coupon, n = Original price of an item, m - Actual cost of an item, a
do you have a z table chart to look at?
find Z= 0 should show that z=0 = 0.500
and z=2.16 = 0.9846
subtract them
0.9846-0.500 = 0.4846 is the area
Knowing that m=n, n is also 37
Now, we know a triangles angles all add up to 180
Add up the two known angles, n and m
37+37=74
180-74=106
O=106 n=37
