Answer:
1.1x
x + 0.1x
Step-by-step explanation:
The manager of a store marks up all items by 10%.
So, if the original price of any item is x, then increase for markup is 10% of x i.e. .
Hence, the expression that represents the new price with the markup is (x + 0.1x) = 1.1x.

Answer:
12/15 and 16/20
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
12/15 simplified is 4/5.
16/20 simplified is 4/5

<u>Given expression is </u>

can be rewritten as

We know,

And

So, using this identity, we


can be further rewritten as





<u>Hence, </u>
