N + d = 30
0.05n + 0.10d = 2.20
^^ ur system of equations
Answer:
1/4 ( p - 1/4 q^2).
Step-by-step explanation:
p/4 - q2/16
The greatest common factor is 1/4 so we have the answer:
1/4 ( p - 1/4 q^2).
1 st you do distributetive property so 4 times x is 4x and 4 times 3 is 12 then you distribute the other side so 2 times 6 is 12 and 2 times 2x is 4x
So now u have the equations 4x + 12 = 12 + 4x and now u can tell that they are equal to each other by using communative property
