Simplify the expression: 10c - 3c + 7.

Simplify the expression: 10c - 3c + 7.

• A. 7c + 7
• B. 3c + 7
• C. 10 + 3c
• D. 7 + 7c

Answer: (B)

To simplify the expression 10c - 3c + 7, we first focus on combining the like terms. The like terms in this expression are the terms that contain the variable 'c'. These terms are 10c and -3c. When we combine them, we perform the operation 10c - 3c. This results in 7c, because if you take 3 from 10, you are left with 7. Next, we bring down the constant term, which is +7. Now our expression reads as follows: 7c + 7. This is a simplified expression, and it correctly reflects the sum of the like terms and the constant. Therefore, the simplified form 7c + 7 is indeed the right result. The other options may contain similar terms but do not represent the correct combination of like terms from the original expression. So the correct answer is reflected correctly in the simplification process that combines the like terms appropriately.
