5x + 2 must be equal to 17. Subtract to from both sides, then divide both sides by 5 and x = 3. 3y - 6 must equal 21. Add 6 to both sides, then divide both sides by 3, and y = 9.
it's either 2/3 or 66.6 (neverending 6s)
First, find the length of the hypotenuse using the Pythagorean theorem: a^2+b^2=c^2
25 + 144 = c^2
= c^2
13 = c
Now, find each of the values! Sin = opposite/hypotenuse; Cos = Adjacent/hypotenuse; Tan = Opposite/Adjacent.

Answer:
34.54 inches.
Step-by-step explanation:
The formula for the circumference of the circle is given as
, where
is rounded to 3.14 and d is the diameter of the circle, 11 inches. Simply plug these values into the equation for the circumference to get your answer:

C = 34.54 inches
2 times the square root of 7 is 14
