Answer:
Adult ticket: $7 Student ticket: $11
Step-by-step explanation:
First, we set up our equations.
x (adult ticket) y(student ticket)
For the first day, 11x + 3y = 110
For the second day, 3x + 6y = 87
Then we solve.
(-2)11x + 3y =110
Equals
-22x - 6y = -220
Add them
-22x - 6y = -220
3x + 6y = 87
This equals
-19x = -133
x = 7
Plug in to find y
3(7) + 6y = 87
21 + 6y = 87
6y = 66
y= 11

Answer:
the correct choice is marked: x = 11; Q = 55°
Step-by-step explanation:
If P and Q are supplementary, then ...
Q = 180° -P
Q = 180° -125°
Q = 55°
Then we have ...
5x = 55°
x = 11°
So first, we need to find a common denominator, make the numbers below the line equal to each other
to do this, we multiply the denominator AND numerator of 4/10 so you can get the equivilent fraction with a denominator of 100
4*10=40
10*10=100
4/10=40/100
now we add the two fractions together and we get
38/100+40/100=
78/100 of a meter
