Question

what is the value of my to the nearest tenth when 0.45m-0.7m=50.55? F:-202.2 G:-144.4 H 44.0J-20.2

Today we have a rather easier math problem to solve.2. First we must figure out the following definitions:- Value is . . . - nearest tenth . . . - dividing decimals. . .3. Yes, you must find out what rounding an answer to the nearest tenth place really means!Let me show you an example:Looking at 2.53, round this value to the tenth means it becomes 2.5Why you ask, okay. I will tell you. The digit 5 is in the tenth place. Do you round to 6 or stay as a 5?Will it depends on what follows digit 5. If it is 5 or higher , then the digit goes up by one of course.Since the digit 5 is followed by 3, then 5 stays as it is. Sorry for the long explanation, I just want to review the rules with you once more.4. Now, lets do some basic COMBINING LIKE TERMS:0.45m - 0.7m = 50.55Watch out, looks like you will have a negative value here. Yes, -0.25m = 50.55Isolate the variable m is to divide both sides by -0.25Lets do that now:-0.25m/ -0.25 = 50.55/ -0.25This leaves with only one possible soluation:m = ???????Remember, this solution is a decimal. What is it?????Good Luck dividing.

Answer 1

今天我们有一个很简单的数学问题解决。2。首先我们必须弄清楚以下定义：值。..最近第十。..分位数。3。是的，你必须找出舍入到最近的第十位的答案真的就是！让我给你一个例子：在2.53，这一值第十意味着它成为2.5why问你，好吧。我会告诉你。数字5是第十位。你轮6或5停留？它将取决于以下的数字5。如果是5或更高，然后该数字上升的课程之一。由于数字5后面是3，那么5就可以。很抱歉长的解释，我只是想和你再次审查的规则。4。现在，让我们做一些基本的结合就像条款：0.45m - 0.7m＝50.55watch，看起来你会有一个负的值。是的，-0.25m = 50.55isolate变量m是划分双方的-0.25lets现在做的：只有一种可能的解决方案-0.25m/ -0.25 = 50.55/ -0.25this叶：M =？？？？？？？记住，这个解决方案是一个小数。这是怎么一回事？？？？？好运气的划分。请你们做出选答便说出为什么！
a：- 202.2
b：- 144.4
c：44.0
d：20.2
我到最近的第十时0.45m-0.7m = 50.55的价值是什么？
