Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
X=7
Step 1: add nine to both sides it becomes
-2x=-23+9 —> -2x=-14
Step 2: divide by -2 on both sides it becomes
X=-14/-2 —> x=7
