Dominique and juan are finding -3 -14. who is correct? dominique -3-14=3+14 =11 juan -3-14=-3+(-14) =17

In this question , we have to remeber the rule of combining two negative numbers . And the rule is, when combining two negative terms, we have to add them with negative sign .For e.g.-2-15=-(2+15)=17. SImilarly, -3 -14 =-(3+14)=-17. And none of them got -17. Dominique got 11 and Juan got 17. So none of them is correct .

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
