A farmer wants to plant peas and carrots on no more than 400 acres of his farm. If x represents the number of acres of peas and
levacccp [35]

Answer:

B.

Step-by-step explanation:

It doesn't make sense for either x or y to be negative because we are talking about x representing the number of acres and y representing another number of acres and that they should add up to no more than 400.

So I'm not going to look at A or C.

B looks good 250+150=400

D almost looks good 1+400=401; the problem with this answer is that is more than 400

A total of 574 tickets were sold for the school play. They were either adult tickets or student tickets. There were 74 more stud
N76 [4]

The answer is: 250 adult tickets were sold.

To be safe, prove that your answer is correct.

If there are 74 more student tickets than adult tickets, the amount of adult tickets must obviously be less.

Explanation:

74 more than 250, or 250+74 is 324.

250+324=574.

Now, you know the answer is correct. It satisfies all of the given conditions.

Also, note that the difference between the number of student tickets and adult tickets is 74.

So, there are 250 adult tickets and 324 student tickets.
