Question

Ada is putting autographed baseballs in a display case. The display can hold 28 baseballs, and there are already 17 baseballs in the case. Ada thinks that she can display 9 more baseballs and the display case will be full. How can you use the equation 17 + b = 28 to check if she's right?

Answer 1

Using the equation 17 + b = 28, we calculate that 17 + 9 equals 26, which is less than the maximum capacity. Thus, Ada can actually put 11 more baseballs in the display case.

Step-by-step explanation:

To check if Ada can display 9 more baseballs so that the display case will be full, we can use the equation 17 + b = 28. In this equation, b represents the number of additional baseballs Ada can put in the display case. Since there are already 17 baseballs in the case, we simply add 9 to 17 and check if the sum equals 28, the total number of baseballs the case can hold.

Performing the addition, we find:
17 + 9 = 26

Comparing the sum to the total capacity of the display case (28), we see that adding 9 baseballs to the existing 17 will give us 26 baseballs in total, which is two less than the maximum capacity of the display case. Therefore, Ada's assumption is incorrect, and she can actually display 2 more baseballs than she thought (9 + 2 = 11 total additional baseballs).

Answer 2

You can use the equation " 17 +b = 28 " to check is she's right because 17 +b has to be 28 baseballs.

Step-by-step explanation:

Sorry for that answer but what I meant was that 17 + b (How many baseballs can be added) must be 28. Now you can subtract both sides by 17 to isolate b by itself. When you do that you get b= 11. So you can add 11 more baseballs instead of 9, therefore she is wrong.

You can check this by putting 11 in for b in the equation. 17+11=28. This is correct.

Hopefully this helped you.
