Answer:
Step-by-step explanation:
a + d + m + r = 16
a = d + 3......d = a - 3
a = m + 2.......m = a - 2
m = r + 1.......r = m - 1.......r = (a - 2) - 1......r = a - 3
a + (a - 3) + (a - 2) + (a - 3) = 16
4a - 8 = 16
4a = 16 + 8
4a = 24
a = 24/4
a = 6 <==== andrew scored 6
d = a - 3.....d = 6 - 3.....d = 3 <=== danielle scored 3
m = a - 2......m = 6 - 2.....m = 4 <==== mel scored 4
r = a - 3......r = 6 - 3 ......r = 3.......renee scored 3

Answer:
a) P = (-3, 4, 3)
b) P = (7, 4, 1)
Step-by-step explanation:
a) You want Q-P = (5, 4, -1) where Q = (2, 0, 2). Solving for P, we get ...
P = Q - (5, 4, -1) = (2-5, 4-0, 2-(-1))
P = (-3, 4, 3)
__
b) The vector in the opposite direction of the one given is the given one multiplied by -1.
P = Q - (-1)(5, 4, -1) = (2+5, 0+4, 2-1)
P = (7, 4, 1)
