Well, a pair of students means two. if there are 24 students then there are: 24/2 = 12 pairs of students.
9 pairs already got their magnets. 12 - 9 = 3 pairs still need magnets.
each pair gets 3 magnets. So he needs 3*3 = 9 more magnets
Quantity is two numbers multiplied together, judging by the context, the answer is D, insufficient information.
Choice a and b are just numbers.
Answer: 11.95
Explanation:
1.5 x 4.5 = 6.75, therefore there is 6.75 more inches than before so you add that to the 5.2 inches already on the ground
5.2 + 6.75 = 11.95
1. opposite sides are equivalent , opposite angles are equivalent
2. 4 sides, 4 angles, both answers for number one also work
3. A square
Since it says -81 + -14, you add those two numbers which is 95 the you would add a negative because the highest number is negative. So the answer is -95 ft.
