Hey there!
You need to not that BF is half the value of EC. So, we could say:
32/2= 16
16=2x-10
Add 10 to both sides.
26= 2x
Divide by 2 on both sides.
x=13.
I hope this helps!

Try to get all the x'es to the right side
Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
It's around a right angle. just put anything around the right angle bc its right of its 10 or less apart
Answer:
2 gallons
Step-by-step explanation:
25% of 4 gallons is 1 gallons, which means that 75% of the hand sanitizer is not alcohol, and is 3 gallons. since that is the amount of not alcohol, and we want it to be 50% solution, it has to be 3 gallons of alcohol in total, and 3-1=2.
