The answer is all of the students are members of the frequent visitor program.
Let x be the number of students that are members of the frequent visitor program.
Let y be the number of students that are not members of the frequent visitor program.
There are in total 19 students: x + y = 19
x students will pay $11, y students will pay $13 for the ticket. Totally, it will be $209: 11x + 13y = 209
Now, we have the system of two equations:
x + y = 19
11x + 13y = 209
____________
Use the method of substitution:
x + y = 19
⇒ x = 19 - y
____________
11(19-y) + 13y = 209
11·19 - 11·y + 13y = 209
209 - 11y + 13y = 209
____________
Rearange:
13y - 11y = 209 - 209
2y = 0
⇒ y = 0
Since y = 0, x = 19:
x + y = 19
x + 0 = 19
x = 19
This means that all of the students in the group are members of the frequent visitor program.
Answer:
It is 2 1/2
Step-by-step explanation:
Hope this helps :)
If the angle is 1/12 of the circle, and a circle is 360 degrees, then our answer will be 1/12 of 360.
1/12 * 360 = 30 degrees
The answer is 30 degrees.
50/2. It equals 25 which isn't a decimal. 50.1 (repeating), 50.1, and the square root of 50 are all decimals.
To find the upper and lower bounds we have to add 5 to 32 AND subtract 5 from 32 to get 37 and 27 respectively.
write it out like this 27 < x <37
