Jane has 3 times as many cards as Peter. The average number of
cards owned by the two children is 64. How many cards does Jane have​

Answer 1

Answer:

64

Step-by-step explanation:

You can write this out as:

3x+x=64

X represents the number of cards Peter has, with 3x being the three times the number of Peter’s cards, equaling to the total number of Jane's cards.

If you add the Xs together:

4x=64

Then divide by 4 on both sides:

X=16

You have how many cards Peter has.

Take that and multiply it by 3 to get the total number of cards Jane has 48 (3 times Peter's).

You can check by adding Peter's cards and Jane's cards:

16+48=64

Which equals the total number of cards, 64.
