Can anyone help me with this pls . I really need this done today I need help with number two.

2x - y - 5z

Step-by-step explanation:

Given

-[z - 3y - (3x - z - 2y) + 3z + 2y] - x =

Distribute the subtraction into the ()

-[z - 3y -3x + z + 2y + 3z + 2y] - x =

Move the terms around, keeping the sign with the term

-[z + z + 3z - 3y + 2y + 2y - 3x] - x =

Combine like terms

-[2z + 3z - 3y + 2y + 2y - 3x] - x =

-[5z - 3y + 2y + 2y - 3x] - x =

-[5z - y + 2y - 3x] - x =

-[5z + y - 3x] - x =

Distribute the subtraction into the []

-5z - y + 3x - x =

Combine like terms

- 5z - y + 2x

Reorder:

2x - y - 5z

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

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.
