Question

Add these two expressions.(–45t + 53s) and (–3 – 75s + 2t)

A. 6/5t + 4/15s – 3
B. –14/5t – 11/5s – 3
C. –115t + 113s – 3
D. 11/5t – 4/15s + 2

Answer 1

Adding the given expressions by combining like terms results in -43t - 22s - 3, which does not match any of the provided options, suggesting a possible error in the question or answer choices.

Step-by-step explanation:

To add the two expressions (-45t + 53s) and (-3 – 75s + 2t), we combine like terms, which means we add coefficients of the same variables and constants together.

• For the variable t, combine -45t and +2t to get -43t.
• For the variable s, combine 53s and -75s to get -22s.
• For the constant terms, simply add -3 to the expression since there are no other constant terms to combine with.

Therefore, the result of adding the given expressions is -43t - 22s - 3, which isn't an option in the given choices, implying a potential error in the question or the answer choices.
