Negative X +3+ 3X equals 23

X = 10

Step-by-step explanation:

First you subtract -X from 3x to get 2x +3 =23

then you subtract 3 from both sides to get 2x = 20

then finally, you divide both sides by two to get x = 10

And if you plug 10 back in you get -10 + 3 + 30 = 23

-10 + 3 = -7

-7 + 30=23

23=23

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.
