Q. Rewrite in simplest terms: 0.1(4v−10w)−4w−0.3(−9w+4v)Answer:
Distribute 0.1 into terms: First, distribute 0.1 into the terms inside the first set of parentheses: 0.1×4v and 0.1×−10w.0.1×4v=0.4v0.1×−10w=−1wSo, the expression becomes 0.4v−1w−4w.
Distribute −0.3 into terms: Next, distribute −0.3 into the terms inside the second set of parentheses: −0.3×−9w and −0.3×4v. −0.3×−9w=2.7w −0.3×4v=−1.2v Now, add these to the expression: 0.4v−1w−4w+2.7w−1.2v.
Combine like terms: Combine like terms: 0.4v with −1.2v and −1w with −4w and then with 2.7w. 0.4v−1.2v=−0.8v−1w−4w=−5w−5w+2.7w=−2.3wNow, the expression is −0.8v−2.3w.
