Answer:
42 + 14
Step-by-step explanation:
By counting the rows and columns, you'll notice the following:
1) The first pattern has 2 columns and increase by 1 column each time you move to the right.
2) The first pattern has 1 row and increase by 1 row each time move to the right.
3) To get to the 7th number, you will have to move to the right 6 times.
Hence,
1) if you start with 2 columns, and move 6 times to the right, each time adding one column you will end up with 2 + 6 = 8 columns
2) if you start with 1 row and move 6 times to the right, each time adding one row, you will end up with 1 + 6 = 7 rows
3) You will end up with a pattern with 8 columns and 7 rows and the number of dots will be 8 x 7 = 56.
If you work out all the answers, yo uwill see that only 42 + 14 gives you 56.
Alright. In this problem, Sharon has 72 cm TOTAL of ribbon. But, she uses 24 of it at first. So you’d have to subtract 24 from 72 to get 48. Then, since she uses the remaining ribbon for each small gift, you’d have to do 48 divided by 6. Your answer will be 8.
Sharon will use 8 cm of ribbon on each gift.
