If [tex]\( b \)[/tex] is the number of baseballs, which algebraic expression represents the phrase "the number of baseballs minus 3 lost during practice"?

A. [tex]\( b \div 3 \)[/tex]
B. [tex]\( b - 3 \)[/tex]
C. [tex]\( b \cdot 3 \)[/tex]
D. [tex]\( b + 3 \)[/tex]



Answer :

Certainly! Let's interpret the phrase and derive the algebraic expression step by step.

The phrase given is "the number of baseballs minus 3 lost during practice."

1. Identify the variable:
- We're given that [tex]\( b \)[/tex] represents the number of baseballs.

2. Understand the phrase:
- "Minus 3 lost during practice" means we need to subtract 3 from the total number of baseballs.

3. Construct the expression:
- "The number of baseballs" is [tex]\( b \)[/tex].
- "Minus 3" indicates a subtraction of 3 from the number of baseballs.

Putting these together, the expression that represents "the number of baseballs minus 3 lost during practice" is:
[tex]\[ b - 3 \][/tex]

Now, let's look at the provided choices:

- Choice A: [tex]\( b \div 3 \)[/tex] - This represents the number of baseballs divided by 3, which does not fit our phrase.
- Choice B: [tex]\( b - 3 \)[/tex] - This correctly represents subtracting 3 from the number of baseballs, matching our phrase.
- Choice C: [tex]\( b \cdot 3 \)[/tex] - This represents the number of baseballs multiplied by 3, which is not what the phrase indicates.
- Choice D: [tex]\( b + 3 \)[/tex] - This represents adding 3 to the number of baseballs, which does not match our phrase either.

Thus, the correct algebraic expression is [tex]\( b - 3 \)[/tex], which corresponds to choice B.

Therefore, the correct answer is:
[tex]\[ \boxed{B} \][/tex]
