R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2
Answer:
Step-by-step explanation:
y + 4 = 2(x - 2)
y + 4 = 2x - 4
y = 2x - 8
6 - x/10 = -3
6 = -3 + x/10
9 = x/10
90 = x
The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions.
2/5 = 18/45
4/9 = 20/45
Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
