When you say "which," it sounds like it should be multiple choice. Anyways, here's the simplified form of
(When simplifying fractions, you should <em>never</em> have a square root on the bottom. Multiply by the square root to cancel it out)
Answer:
$19.85 tip
Step-by-step explanation:
To find the % of something simply turn 20% to a decimal (.2) then times it by the number you want .2 * 99.25 = 19.85
2 because 2*2 will get u 4 and 2*3 will get you 6 so Alicia is thinking of the number 2
Parentheses indicate multiplication (no need to use the "*" sign).
So the question is basically asking for the usage of multiplication and addition only.
To get 13 through the given combination using only parentheses and addition, you can write it as follows:
3 + 2(4+1) = 13
Now, let's check this:
3 + 2(4+1)
= 3 + 2(5)
= 3 + 10
= 13 which is the required output.
