We need to split the problem into two cases to remove the abs sign. Case 1: 5x - 6 >= 0, equivalent to x >= 6/5. In this case the problem is now to find the values of x that satisfy x² &g...

300 x 1/10

= (300/10) x 1

= 30 students sat on chairs

85% of 300 

= (300/10) x 8.5

= (30 x 8) + (30 x 0.5)

= 240 + 15

= 255 students sat on the floor

An improper fraction is any fraction where the order of the constant (power of x) is equal or greater in the nuberator than the denominator, take for example;

(x²-3x-2)/(x²-3x...
