Answer:
40 girls
Step-by-step explanation:
Set up a proportion where x is the number of girls in band class:
= 
Cross multiply and solve for x:
3x = 120
x = 40
So, there were 40 girls in band class.
It is 9. You have to add 33y, then divide by 11 and you get x = 3y + 9
The expanded form is adding all the digits so the answer is
700+50+7+0.9+0.02+0.003
Answer:
It should be (2,9).
Step-by-step explanation:
If you rotate it counter clockwise, the x value and y value switch numbers and they will both become postive.
Points
on the circle satisfy
.
Points inside the circle satisfy
.
Points outside the circle satisfy
.
We have

so the point (2, 8) lies inside the circle.
