Step-by-step explanation:

k(2k-5)-3(2k+5)

2k-5-3(2k+5)

2k-5-6k+5

+5 +5

2k-6k+10

+6k +6k

8k+10

2k

-50/3 is the final answer! : )

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.
