Answer:
23.87
Step-by-step explanation:
Answer:
X=132-13A/A, A cannot equal 0
A=132/X+13, X cannot equal -13
11x11 is 121 a way to remember it is there is one number on the left one number on the right and they add up to be 2 numbers total
Step-by-step explanation:
let 1 pound of nail = x
so, the carved out waste nail will be = 12x
total nails = 13x
so the equation is =
13x - 12x = x
OR
x + 12x = 13x
Or
13x - x = 12x
