The cost of a senior citizen ticket is $15 and the cost of a student ticket is $12.
How did I get this?
We know that 6 citizen tickets and 7 student stickers sold for $174 the first day. And 10 citizen tickets and 14 student tickets sold for $318 the second day.
1. create two equations out of this: C= citizen cost per ticket and S = student cost per ticket.
6C + 7S = $174
10C + 14S = $318
2. Use process of elimination. Multiply the first equation by 2 because we want two variables to cancel out.
-12C - 14S = -$348
10C + 14S = $318
Combine like terms.
-2C = $30
Divide by -2 on both sides. The left side cancels out.
C = $30/-2
C = -$15 (In this case the negative doesn't matter)
C = $15 (cost of senior citizen ticket)
Plug the value of C into any of the two equations so we can get the value of S.
6($15) + 7S = $174
Distribute the 6 into the parenthesis.
$90 + 7S = $174
Subtract both sides by $90 and the left side will cancel out.
7S = $84
Divide both sides by 7.
S = $12
Student ticket: $12
Senior citizen ticket: $15
9/10 : 1/10 = 45,000,000 : x
x = 45000000/9 = 5,000,000
Answer: 5 million acres
45 because 180 divided by 2=90 and 90 divided by 2= 45 because she needs area which is length times width= area and area divided by length or width= the other
Answer:
LCM of 5, 10, and 12 is 60
6, 10, and 12 is 60
2, 4, and 9 is 36
Answer:
reflex angle
Step-by-step explanation:
Acute is less than 90
Right = 90
Obtuse is greater than 90 and less than 180
Straight is 180
Reflex is greater than 180 and less than 360
This is greater than 90 and less than 180 so it is a reflex angle
