Answer:

Step-by-step explanation:
This question is to simplify and take "common" of the expression given.
The expression to simplify is:

From the number, we can take "3" out
From x, we can take
out
From y, we can take
out
That means we take out: 
So, it leaves us with:

This is the simplified form: 
Answer:
-1 / 2
Step-by-step explanation:
just submit that
Answer:
£45
Step-by-step explanation:
Say the original price is x. When we take 20% off, that's basically multiplying x by 20% and then subtracting that product from the original price, which is x:
x - 20% * x = 80% * x = 0.8x
Now, this equals £36, so we just set them equal:
0.8x = 36
Dividing by 0.8 from both sides, we get:
x = £45
Thus, the answer is £45.
