Step-by-step explanation:
Answer would be A- 6x+20 his siters gift is x, (x)6=6 x
moms gift and wifes gift are each a (2x) than his two (2x) and 2(x's) = 6x.
2x+2x+x+x=6x, so now 6x+20 equals total ammount spent (total budget)

X = 4
I'm pretty sure it's right
Answer:
I am not sure if this is right but the answer is
The area of a circle with circumference 18π is 254.5
To convert from rectangular coordinate (x, y) to polar coordinate (r, θ).
r is given by the square root of the sum of the squares of the rectangular coordinate.

and θ is given by the arctan of the ratio of y to x.

Example:
To convert rectangular coordinate (3, 4) to polar coordinate

Therefore, rectangular coordinate (3, 4) = polar coordinate (5, 53.13°)
