w is the weight of Diego's dog. The weight must be more than 10 (w>10) but less than 15(w<15), so the inequality must be 1010 and w<15 then the following inequalities should be true:
w>11
(The weight can be more than 11 kilograms as long as it does not go past 15 kilograms.)
w>10
(This is one of the original inequalities. Weight has to be more than 10.)
w<15
(This is also one of the original inequalities. Weight has to be less than 15.)
w<11
(The weight can be less than 11 as long as it is more than 10.)
Not true:
w>15
(The weight cannot be more than 15 as stated in the question.)
w<10
(The weight cannot be less than 10 as stated in the question.)
