1 answer:
Answer:
D:
Step-by-step explanation:
Let:
A:
This is easy, simply R=4, and we don't know the value of G, so:
B: Be careful here, we know the numbers add to 5, so we don't know the exact value of R or G, because R could be 4 and G could be 1 or R could be 2 and green could be 3. However we can be sure that they can´t have the same value, because 5 is an odd number, if we add the same number to a number the result is always even: n+n=2n. So:
C: R is 3 or G is 3, that's the only thing we know, hence:
D: Similar to B, we only know that the sum of R and G isn't 8:

Answer:
- 18 baseball cards
- 12 football cards
Step-by-step explanation:
The only relationship shown in the table is in week 1, where the ratio of baseball to football cards is ...
baseball : football = 9 : 6
In week 1, the total of these numbers is 15. You want the total in week 5 to be 30, double the total in week 1. So, Thomas needs to purchase double the numbers he purchased in week 1:
- 18 baseball cards
- 12 football cards

This table came from another question you posted, a question with no content other than the table. The blue numbers are blanks in the original table that have been filled in so as to keep the same 3:2 proportion in each week. They appear to have no bearing on this question.
