1.Express that x differs from -7 by more than 3 as an inequality involving absolute value.
Solve for x.
2.A landscaping company sells 40-pound bags of top soil. The actual weight x of a bag,
however, may differ from the advertised weight by as much as 0.75 pound. Write an
inequality involving absolute value that expresses the relationship between the actual
weight x of a bag and 40 pounds. Over what range may the weight of a 40-pound bag of to
soil vary?

1. 用一个含有绝对值的不等式表示此关系: x 与 -7 相差大于 3 , 并求出 x (的范围) .

2. 一家景观美化公司出售袋装表土, 每袋 40 磅. 然而一袋表土的真实重量, 与标示的重量可能相差多达 0.75 磅. 请用一个含有绝对值的不等式表示一袋表土的实重 x 和 40 磅的关系. 这种一袋 (标示为) 40 磅表土的重量可能会在哪个范围内变化?

(倒数第二行右边是否为 40-pound bag of top soil ? 好像掉了一个 p ...)

LZ 还需要帮忙解题吗? 翻译成中文应该就比较简单了. 加油吧!

希望我的回答能对你有帮助!
