PLEASE HELP TIMED TEST HELP!!!!!!!!

Annika sells 6 inch pies for $5.00 and 8 inch pies for $9.00 each. Last week she sold twice as many 6 inch pies as she did 8 inch pies. She made $133.00 from her sales. Annika defined x as the number of 6 inch pies she sold and y as the number of 8 inch pies she sold. She wrote the system below.


6x+8y=133

2x=y


Which statements about the system are true? Check all that apply.

1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133


2.Since the 8 inch pies are 2 inches larger, the second equation should be x+2=y


3.Since there are fewer 8 inch pies, the second equation should be x=2y to balance the values.


4.The first equation is correct because 6x represents the money earned for 6 inch pies and 8y represents the money earned for 8 inch pies.


5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.

Answer 1

Explanation:

The equations that she wrote are

6x+8y=133

2x=y

The following statements about the system are true

1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133

5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.

The following statements are wrong because,

2. Because there was no relationship between the number of pipes sold and the size of each pipe.

3. x=2y shows that there are more 8 inches pipes

4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost
