What is the constant of proportionality (unit rate) for the following equation:
a = 156 · n

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.

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.

5x10^11 x 65

325 x 10^11

or

325,
