The price of 2 pears and 6 apples is $14. The price of 3 pears and 9 apples is $21. Can you determine the unit prices for pears
aliina [53]

Answer:

If 2p + 6a = $14

and 3p + 9a = $21

 then the following would also be true:

 1p + 3a = $7

 

If p = pear and a = apple, how much would each cost?  The unit prices can be determined by looking at the pattern. You can use multiplication to solve the problem.  

 For example, 1p + 3a*2 = $7

 

p = $1/each

a = $2/each or $6 total

Hello.

1. The outcome would be 1/7 beacuse there are 7 days in a week and there is only one day.

2. <span>0.14285714 and 1/7 

3. The answer is neither likley or unlikley.
Its not impossble becasue there is a good chance that could happen. 
It wouldnt be likley beacase a 1 to 7 ratio is pretty small when there is 6 more oprtions.
And not unlikley or likley becasue there is a good chance it could happen so the answer would be unlikley.

Have a good day.</span>
