What is the answer ?

Ugo [173]

The tip is $15.73. I get that by multiplying 78.63 and .20. then you add the tip to the bill and get $94.36. you then find the discount by multiplying 94.36 and .15. the discount is 14.15. then subtract 14.15 from 94.36 to get your total.

the answer is $80.21

Answer: $2x^{2}+2x$

Step-by-step explanation:

2. You know the height and the base, which are given in the problem. Then, you only need to substitute them into the equation shown above and simplify it, as following:

$Area=\frac{2x(2x+2)}{2}$

$Area=x(2x+2)\\Area=2x^{2}+2x$

What is the fractional equivalent of 225%?

vitfil [10]

You would start out by putting 225 over 100 then simplifying from there. You would end up getting 9/4. As a mixed number that would be 2 and 1/4.
