Answer:

Two negatives make a positive.

-75 - (-20) = -75 + 20

Do the math now:

-75 + 20 = -55

Write down the final equation to get the answer, which is finding the difference between 56 and -55:

Two negatives again...they make a positive, so re-write the equation:

56 - (-55) = 56 + 55

Get the answer by solving:

56 + 55 = 111

Answer:

D) 111

Step-by-step explanation:

(-75) - (-20) +x = 56

A negative minus a negative means add

-75 + 20 +x =56

-55 +x = 56

Add 55 to both sides

-55+55 +x = 56+55

x = 111

Does the point (9.5, 144) make sense in this context? Explain
Stolb23 [73]
No, (9.5, 144) does not make sense because there is no point of 9.5 and when you divide the ounces of water by the flavoring packets you end up with 12, and if you were to simplify that it would end up with 1 flavor packet and 12 ounces of water.
