What is -c-d where c is equal to -3 and d is equal to -6

The correct answer would be -3.

This is because

-c = 3

Subtracting a negative number turns in to a positive number so subtracting d would be the same as subtracting 6.

The expression then becomes 3 - 6, which equals -3.

Hope this helps and have a nice day! :)

so, converting firstly the mixed fractions to improper fractions and then "adding".

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
