Answer:
$121.00
Step-by-step explanation:
Together, the tax and tip were 6% and 15% of $100, or 21% of $100. That means the total cost of Marco's mean was ...
(1 +21%) × $100 = 1.21×$100 = $121.00
Answer:
6.66 liters
Step-by-step explanation:
34% of one liter would leave 66% of the liter left, and if you were to add the other 6 liters to it, you would get your answer.
4x² - 16 is the algebraic expression that must be added to get the result as 9x²- 2x - 5.
<u>Step-by-step explanation:</u>
The question is asked for the algebraic expression must be added to the sum of 3x²+4x+8 and 2x2−6x+3 to give 9x²- 2x - 5 as the result.
Therefore,
The first step is to find of sum of 3x²+4x+8 and 2x²-6x+3.
To find the sum :
3x²+4x+8
<u>2x²-6x+3 </u>
<u>5x²-2x+11</u>
The sum is 5x²-2x+11.
Now, the second step is to subtract 5x²-2x+11 from the result 9x²- 2x - 5.
9x²- 2x - 5
- <u>(5x²-2x+11)</u>
<u> 4x² -16 </u>
Thus, 4x²-16 is the algebraic expression that must be added with 5x²-2x+11 to get a result of 9x²- 2x - 5.
