Answer: I think
Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)
Answer:y.5
Step-by-step explanation:5 times 3 = 15/2 = 7.5
4/5 pounds for 3 $
hence for 1$ we get 4/15 pounds
then for 10$ we would get 4*10/15 =40/15 = 8/3
