Let 
be the number of liters of the 10% solution she needs to use. She'd end up with a 6% solution with a volume of 
liters. The starting solution contains 0.04*9 = 0.36 liter of salt. Each liter of the 10% solution contributes 0.1 liter of salt, so that
Solve for :
so Mayra needs to add 4.5 liters of the 10% solution.

Step-by-step explanation:
To find how many licks she does to 1 lollipop, 54 divided by 3 which is 18. So, 18 licks/lollipop. 36/18=2. Which means Olivia licks 2 lollipops in 36 licks. To find 5 lollipops, 18*5=90. She licks 5 lollipops in 90 licks.
<u>Answer</u>
2. 40
<u>Explanation</u>
The angle subtended by the diameter to the circumference is equal to 90°.
∴ angle ABC = 90°
Angles in a triangle = 180°
50 + 90 + x = 180
90 + x = 180
x = 180 - 90
= 90°
