<span>Given
numbers 12.6, 3.1 and 5.4
=> 12.6
=> 3.1
=> 5.4
These 3 are all smaller than 20.
Explain why is it greater than 20?
Very simple, simply add those given numbers
=> 12. 6 + 3.1 = 15.7
=> 15.7 + 5.4 = 21.1
=> 21.1 > 20 , 20 is less than 21.1
That’s that reason why the given numbers is greater than 20. When you add the 3
numbers, the sum is greater than 20.</span><span>

Cross multiply
19(x) = 30(9.5)
Simplify
19x = 285
Divide 19 from both sides
19x/19 = 285/19
x = 285/19
x = 15
B. 15 is your answer
