Square rooting because you have to find the inverse of the equation to solve
4a + 2b = 10
you are solving for b
isolate the b
subtract 4a from both sides
4a (-4a) + 2b = 10 (-4a)
2b = 10 - 4a
divide 2 from both sides to isolate the b
2b(/2) = (10 - 4a)/2
b = (10 - 4a)/2
b = 5 - 2a
C) b = -2a + 5 is your answer
hope this helps
C is also the best answer
100 drops =1fluid ounce
1 drop= 1/100 ounce
Hence
10 drops =10/100=1/10
