3*10 = 10+5*s
30 = 10+5s
20 = 5s
s = 4

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:
Step-by-step explanation:
One of the methods is to first split the face and the denominator of the fraction into first bases:
Let's simplify:
That would be a scalene because none of the sides are congruent (the same size)
