Marvin earns $7.75 per hour at his summer job. He wants to buy a video game system that costs $162.75. Solve the equation to find the number of hours Marvin needs to work in order to afford the video game system.

21 hours

Step-by-step explanation:

$162.75 ÷ 7.75 = y

$162.75 ÷ 7.75 × 7.75 = y × 7.75

$162.75 = 7.75y

7.75 × y = $162.75

7.75y = $162.75

7.75y ÷ 7.75 = $162.75 ÷ 7.75

y = 21

step-by-step explanation:

thats the first half

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.
