2x+7=3(x-4) type out your steps

x=19

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x+7=3(x−4)

2x+7=3(x−4)

2x+7=(3)(x)+(3)(−4)(Distribute)

2x+7=3x+−12

2x+7=3x−12

Step 2: Subtract 3x from both sides.

2x+7−3x=3x−12−3x

−x+7=−12

Step 3: Subtract 7 from both sides.

−x+7−7=−12−7

−x=−19

x=19

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.
