Answer:
senior tickets sold: 12
child tickets sold:8
Step-by-step explanation:
Let
x= amount of senior tickets sold
y= amount of child tickets sold
For the first equation, it should look like:
200=14x+4y
For the second equation, it should look like:
92=7x+y
So this is a systems of equations problem. So I will use substitution as it is easier:
1.) Take one of the equations (in this case ill take 92=7x+y) and make one variable have a value, in this case ill isolate the y.


2.) Take the value of y and plug it into "y" into the other equation to solve "x"

<u><em>(editor's note:instead of dividing it by 14, I multiply by 1/14 as it would look complicated in the equation solving steps)</em></u>
3.) Then plug the value of "x" to one of the equations to solve for "y" (which I'll use the 92=7x+y)

Answer:
0 to -180 is the same rotation as -180 to -360
Step-by-step explanation:
0 to -180 is clockwise direction. since the rotation is of a total of 180 degrees, which means that from any angle, it has to rotate an extra 180 degree clockwise. Furthermore, another answer could be from 180 to 0, or 90 to -90, etc.
Had to do this since it’s kinda hard to type it out
