The total money spent for the Dinner and Dessert is $22 so to figure out how much was spent on the taxi ride you're going to want to subtract $22 from $31 (31 = x + 22) or (31 - 22 = x).
Answer:
Mean = 4
Step-by-step explanation:

Answer:
-45
Step-by-step explanation:
When the -4 is plugged in, it needs to be multiplied and then added to 39. That equals -45.
Start with where the shorter leg is. It must be opposite the smallest angle.
In a 30 - 60 - 90 degree triangle you have the hypotenuse to be twice as long as the shortest side. You have to read that a couple of times to make sure you understand it.
That being said, if the shortest side is x, the hypotenuse will be 2x.
Since in this case the shortest side is 11, the hypotenuse will be 2*11 = 22
22 <<<<<< answer.
When multiplying fractions, multiply straight across:
(-3/7) (6/5) =
(-3 * 6) / (7*5)=
-18/35
The answer is B.
