13.3cm rounded to the nearest 10th
3x + 2 = 5x - 8
Flip
5x - 8 = 3x + 2
Subtract both sides by 3x
2x - 8 = 2
Add both sides by 8
2x = 10
Divide both sides by 2
x = 5
That's your answer.
Have an awesome day! :)

The strategy that Lucy uses to recall her phone number is what is known as Chunking.
<h3>What is Memory?</h3>

we know that A has 60% of salt, so if way we had "x" amount of ounces of A solution the amount in it will be 60% of "x", or namely (60/100)*x = 0.6x.
Likewise for solution B if we had "y" ounces of it, the amount of salt in it will be (75/100) * y or 0.75y, thus

Answer: 9 square units</h3>
Explanation:
The diagram is shown below.
Side AC is the base which is 6 units long (since 9-3 = 6)
Side AB is the height which is 3 units
area = base*height/2 = 6*3/2 = 18/2 = 9
