well if you know distributive property.....

4(x-3) = (4)(x) + (4)(3) = 4x-12

and $4x-12 =4x-3\\4x-4x-12= 4x-4x-3\\-12 \neq -3$ False not equivalent

$(2n)^{3} = 2^3*n^3=8n^3\\ 8n^3 = 8n^3$ These expressions are equivalent

Last one.... $\frac{6x-3}{3} = \frac{3(3x-1)}{3} = 3x-1\\ 3x-1\neq 2x$ False not equivalent

25 Cards

Step-by-step explanation:

If 5 cards is 20% and you only need 5 more then that means you have the other 80%. So you 20 80/20 which is 4. Then do 4x5=20 then add the 5 you still need.
