Divide both sides by 2 for the first one.
2c/2>2/2
c>1
simplify both sides for the second 1
1/6d>=1
6*(1/6d).=(6)*(1)
d>=6
For the last one
subtract 9 from both sides
r+9-9<=23-9 so that r<=14
Hope this helps!
I think a but not sure but i hope i helped :D

Answer:
The motion of the particle describes an ellipse.
Step-by-step explanation:
The characteristics of the motion of the particle is derived by eliminating
in the parametric expressions. Since both expressions are based on trigonometric functions, we proceed to use the following trigonometric identity:
(1)
Where:
(2)
(3)
By (2) and (3) in (1):

(4)
The motion of the particle describes an ellipse.
So we start with the $60 untouched.
Then we add the tax which is $60•0.07= 4.20 that is the tax
Then add the tax to the total $60 + $4.20= $64.20
Next we must add the tip so $60•0.15= 9.
Then $64.20 + $9.00 = $73.20
Total cost of meal $73.20
Any questions? :)
