Answer: x=6, y=20
Step-by-step explanation:
Since ΔBCD and ΔTUS are congruent triangles, we can set the sides equal to each other.
y=2y-20 [subtract both sides by 2y]
-y=-20 [divide both sides by -1]
y=20
--------------------------------------------------------------------------------------
3x+32=9x-4 [add both sides by 4, and subtract both sides by 3x]
36=6x [divide both sides by 6]
x=6

radius would be 14. you get the circumference (87.92) and divide it by pi (3.14) you get 28 which is the diameter and divide it by 2 and you get the radius 14.
Step-by-step explanation:
6700=32000 (0.8)^t
Solve for t
t=log(6,700÷32,000)÷log(0.8)
t=7 years
