The amount owed at a restaurant was $49.82, this included a 6% tip. What was the bill before tax was added?

$46.8308

Step-by-step explanation:

Let the original amount of the bill be x

The amount owned = $49.82(including a tip of 6%)

To get the original before tip was added, we will use the expression;

x = $49.82-(6% of $49.82)

x = $49.82 - (0.06 * 49.82)

x = $49.82 - 2.9892

x = $46.8308

Hence the bill before the tax was added is $46.8308

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
