Rewrite in simplest terms: -2(0.9 m+0.4 n)+7n-8(-0.4 n-0.6 m) Answer:

Distribute -2 into terms: Distribute the -2 into the terms inside the first set of parentheses: -2(0.9m + 0.4n). Calculation: -2 * 0.9m = -1.8m and -2 * 0.4n = -0.8n. So, the expression becomes: -1.8m - 0.8n + 7n - 8(-0.4n - 0.6m).Distribute -8 into terms: Distribute the -8 into the terms inside the second set of parentheses: -8(-0.4n - 0.6m). Calculation: -8 * -0.4n = 3.2n and -8 * -0.6m = 4.8m. So, the expression now becomes: -1.8m - 0.8n + 7n + 3.2n + 4.8m.Combine like terms: Combine like terms: -1.8m with 4.8m and -0.8n with 7n and 3.2n. Calculation: -1.8m + 4.8m = 3m and -0.8n + 7n + 3.2n = 9.4n. So, the expression now becomes: 3m + 9.4n.

Q. Rewrite in simplest terms:

-2(0.9 m+0.4 n)+7 n-8(-0.4 n-0.6 m)

\newline

Answer:

Distribute $-2$ into terms: Distribute the $-2$ into the terms inside the first set of parentheses: $-2(0.9m + 0.4n)$ . $\newline$ Calculation: $-2 \times 0.9m = -1.8m$ and $-2 \times 0.4n = -0.8n$ . $\newline$ So, the expression becomes: $-1.8m - 0.8n + 7n - 8(-0.4n - 0.6m)$ .
Distribute $-8$ into terms: Distribute the $-8$ into the terms inside the second set of parentheses: $-8(-0.4n - 0.6m)$ . $\newline$ Calculation: $-8 \times -0.4n = 3.2n$ and $-8 \times -0.6m = 4.8m$ . $\newline$ So, the expression now becomes: $-1.8m - 0.8n + 7n + 3.2n + 4.8m$ .
Combine like terms: Combine like terms: $-1.8m$ with $4.8m$ and $-0.8n$ with $7n$ and $3.2n$ . $\newline$ Calculation: $-1.8m + 4.8m = 3m$ and $-0.8n + 7n + 3.2n = 9.4n$ . $\newline$ So, the expression now becomes: $3m + 9.4n$ .
