10 x + 3 y=-5
-5 x - 4 y = 10 ​

x=2/5, y=-3. (2/5, -3).

Step-by-step explanation:

10x+3y=-5

-5x-4y=10

10x+3y=-5

2(-5x-4y)=2(10)

10x+3y=-5

-10x-8y=20

-5y=15

y=15/-5

y=-3

10x+3(-3)=-5

10x-9=-5

10x=-5+9

10x=4

x=4/10=2/5

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

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.
