Answer:
Advance ticket costs $25
Same-day ticket costs $20
Step-by-step explanation:
Let x = the price of one the advance ticket.
Let y = the price of one same-day ticket.
The combined cost of one advance ticket and one same-day ticket is $ 45. This means
x + y = 45 - - - - - - 1
For one performance, 30 advance tickets and 20 same-day tickets were sold. The total amount paid for the tickets was $ 1150. This means
30x + 20y = 1150 - - - - - - - - -2
From equation 1, x = 45- y
Put x = 45- y in equation 2
30( 45-y) + 20y = 1150
1350 - 30y + 20y = 1150
-10y = 1150-1350
-10y = -200
y = 200/10 = $20
x = 45-y
x =45-20= $25
Advance ticket costs $25
Same-day ticket costs $20
The answer is x=-7 you just have to cancel the like factors out n you don’t have to divide nothing in this equation.
The expression would show three sevenths of y minus four.
Answer:
Step-by-step explanation:
As a rule, worth remembering, the fractions with denominators of multiples of 2, 5 or combination of the two, result in terminating decimals and all the rest- non-terminating.
<u>Considering this we can state:</u>
- 9/5, 5/16, 3/25, 2/5, 3/20 are terminating decimals
- 7/12, 1/7, 9/11, 11/15, 7/18 are non-terminating or repeating decimals
