Answer 1

Simplifying Expressions

a) To simplify the expression b = 3 + (3/9)a - 2 + (4/9)a + 1 + (1/2)a, we can combine like terms.

First, let's combine the terms with 'a': - (3/9)a + (4/9)a + (1/2)a = (3/9 + 4/9 + 1/2)a

Next, let's combine the constant terms: - 3 + (-2) + 1 = 2

Therefore, the simplified expression is: b = (3/9 + 4/9 + 1/2)a + 2

b) To simplify the expression c = (7/12)m + (1/6)m - (2/3)m, we can combine like terms.

Combining the terms with 'm': - (7/12)m + (1/6)m - (2/3)m = (7/12 + 1/6 - 2/3)m

Therefore, the simplified expression is: c = (7/12 + 1/6 - 2/3)m

c) To simplify the expression d = 2 + (5/6)x - (2/3)x - 1 + (4/9)x, we can combine like terms.

Combining the terms with 'x': - (5/6)x - (2/3)x + (4/9)x = (5/6 - 2/3 + 4/9)x

Combining the constant terms: - 2 - 1 = 1

Therefore, the simplified expression is: d = (5/6 - 2/3 + 4/9)x + 1

I hope this helps! Let me know if you have any further questions.
