Find the exact value of the following.

Find -xy, for x = -75.9 and y = 2.6.

-xy =

197.34

Step-by-step explanation:

-(-75.9 ) × 2.6

-(-75.9)(2.6) = +197.34

Step-by-step explanation:

Find -xy, if x = -75.9 and y = 2.6.  Substitute -75.9 for x and 2.6 for y in -xy:

-(-75.9)(2.6) = +197.34

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.
