Answer:
math = 87
physics = 168
<em>Brainliest, please!</em>
Step-by-step explanation:
Variables:
m = math, p = physics
Equations:
m + p = 255
m = p - 81
Substitution:
m + p = 255
(p - 81) + p = 255
2p - 81 = 255
2p = 336
p = 168
Solving for m:
m + p = 255
m + 168 = 255
m = 255 - 168
m = 87
Checking with the other equation:
m = p - 81
87 = 168 - 81
87 = 87
So, math = 87 and physics = 168

Answer:
2 possible coordinate pairs
N (8, 17) OR (-12, -3)
Step-by-step explanation:
The rule:
(x, y) => (x + 10, y + 10) OR (x - 10, y -10)
(-2 + 10, 7 + 10) OR (-2 - 10, 7 -10)
(8, 17) OR (-12, -3)
