Senior tickets (x)
Child tickets (y)
First day: 3x + 5y = 70
second day: 12x + 12y = 216
Solve the system of equations (use elimination)
Multiply first equation by -4 -4(3x + 5y = 70), which makes it
-12x - 20y = -280
(+)12x + 12y = 216 add to second equation
-8y = -64
divide by -8. y = 8
Plugin the y value to either equation ( I will choose first equation)
3x + 5(8) =70
3x+ 40 = 70
3x = 30
x = 10
Senior tickets are $10, child tickets are $8
Step 1: divide numerator (5) by the denominator (9): 5 ÷ 9 = 0.5555555555555556
Step 2: add this value to the the integer part: 3 + 0.5555555555555556 = 3.5555555555555554. So,
3 5/9 = 3.5555555555555554
Answer:
135
Step-by-step explanation:
x = 135 by the vertical angles theorem
Answer:
No.
x-1 is not a factor of the polynomial
Total = 12 marbles
6 brown marbles but h<span>alf of the brown marbles are made of glass
so brown and made of glass = 3
</span><span>probability that it is a brown, glass marble = 3/12 = 1/4
answer
1/4</span>
