The total restaurant bill for food and drinks is = $63.57

This total bill consists of the prices of the items purchased, and the tip given to the waiter. So, the total bill of only food will contain only the food prices. So, it will be less than $63.57

Now, as it is not mentioned how much tip was given, lets assume that the tip is 10% which is $ 6.357

So, lets subtract it from the total bill. Its $ 57.22. Hence a good estimation is a reduced bill than the given amount of $63.57

Two negative signs together change the sign to a positive sign.

Using the distributive property with the 7 you would have -(-7), the two negatives would make it +7

So you end up with -8 + 7

Answer: $6\ minutes$

Step-by-step explanation:

You can use the following formula:

$\frac{T}{A}+\frac{T}{B}=1$

You can say that "T" is the time (in minutes) for both faucets working together, "A" is the time (in minutes) for cold water faucet working alone and "B" is the time (in minutes) for hot water faucet working alone.

Based on the data given in the exercise, you can identify that:

$T=2\\A=3$
