Answer:
6 times 32 is 192
Step-by-step explanation:
Since there are six classes, and all the classes eat the same amount of food, we know that you would do 6 times X. X is 32, because 1 class ate 32 slices of pizza. So the answer is 32.
87; If he gave two thirds of his remaining cards to Elaine, then he had one third left. If one third of his remaining cards is 25, then 25 x 3 will give you what he had after trading with Tommy. When he finished trading with Tommy he had 75 cards. if he gave away 15 cards, but got three back, then he must have had 87 cards to begin with.
Check your answer:
87-15 = 72
72+3 = 75
2/3 of 75 = 50
75-50 = 25

Answer:
5
Step-by-step explanation:
Quadrant I : cot(x) > 0 → -cot(x) < 0
Quadrant II : cot(x) < 0 → -cot(x) > 0
Quadrant III : cot(x) > 0 → -cot(x) < 0
Quadrant IV : cot(x) < 0 → -cot(x) > 0

Answer: a)
We know that one answer is only true, so we did not check the correctness of the cotangent value, only to the number sign
