Same as original, density = mass / volume, cutting the block in two pieces or any number of pieces doesn't change the density as ratio m/v remains constant.
The number is -2 // Math [n is equivalent to number]: 2n -10 = 7n 2n = 7n + 10 -5n = 10 -n = 2 n = -2 // Hope this helped, please give me brainliest, thanks!! //
