At the denver zoo, adult admission is $15 and children’s is $9 a group of 12 people go to the zoo. their total admission was $150. set up a system of linear equations and solve

15x+9x=150

x+y=12

That's the answer, I bet you could easily solve it now that I have just set it up for you.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

44
