C = 30.8
Step-by-step explanation:
Circumference of a Circle:
C = 2πr
C = 2(3.14)(4.9)
C = 30.772
C = 30.8
Step-by-step explanation:
-4x - 2y = 18
+ (4x - 4y = -36)
=> -6y = -18, y = 3
As we added the equations together, we have eliminated x and found y.
Hence the correct answer is "Add to eliminate x".
392 / 500 double and take one decimal place to see percentage
52/500
56/500 e.g. 56*2 = 112 now take 1 decimal so it is 11.2%
now divide each by 20
