Answers

Answer 1

Answer: Alright now combine all like terms remember no matter what you can allways add like terms ok now it would be 5-3 you should get two now add the n and the squared 2 and 2n2 should be your answer witch is ANow for the other equation 8+-4 =4 3b +6b = 9b now drag the 2c down and you get4+9b-2c I hope this helps you

Answer:

Option A - 5d + $10.00 – $4.00 = $13.50; $1.50

Step-by-step explanation:

Given : John and 4 friends are going out for pizza for lunch. They split one pizza and 5 large drinks. The pizza cost $10.00. After using a $4.00 gift certificate, they spend a total of $13.50.

To write : An equation to model this situation, and find the cost of one large drink.

Solution : Let d be the cost of the drink.

Number of drinks is 5.

The cost of 5 drink is 5d.

The pizza cost $10.00.

Total cost = 5d+$10

After using a $4.00 gift certificate, they spend a total of $13.50.

The equation to model the situation is $5d + 10 - 4 = 13.5$
