2020年4月28日 · 在Github，YouTube，以及各种国外社交媒体上我们经常看到1K，2K，1M，10M这样的数字单位，它们分别代表： 为什么它们被这样简写呢？ 英文中的“千”明明是thousand，不应该写作 1t 吗？ 其实，thousand并不像中文的“千”，它是“数字”而不是“单位”，单位就应该用“kilo”，比喻说： 它写作1kg，读作one thousand grams，确实有些奇怪，其实，因为数学上大量的使用缩写，并对这些缩写进行了详细的规定，使得公制计量单位规定了 …

What is the answer to 7m=7(2m-3) ? The answer to 7m=7(2m-3) is m=3; Solve for m: 7m=7(2m-3) The solution is m=3

2025年2月12日 · To solve for m in the equation 7 m = 7 (2 m − 3), we can follow these steps: Distribute on the Right Side: Start by distributing the 7 on the right side of the equation. 7 m = 7 × 2 m − 7 × 3. Simplifying, we have: 7 m = 14 m − 21. Bring All Terms Involving m to One Side: Subtract 14 m from both sides to get all terms involving m on one ...
