kow [346]

Answer:

145.8 pounds

Step-by-step explanation:

So, if there is 9720 pounds total, and 98.5% of it must be pure paper, than 1 - .985 is how much can be impurities.

1-.985 = .015 or 1.5%

Now lets multiply .015 times 9720

.015(9720) = 145.8

The maximum weight of impurities is 145.8 pounds

How do you complete solving two step equations
Gekata [30.6K]

Answer:

Here's a two step equation for example: 4.8y - 6.9 = 3.18

Step-by-step explanation:

How I solve it is using: Sadmep.

wth is that?

Well, it's pemdas backwards. You use this version for solving 2 step equations. But pemdas, not a two step equation.

But, how to solve it: Sadmep..S stands for subtraction...do I see it? Yes! So we are going to do inverse operations..what's the inverse of subtraction..Addition! So you are going to put an addition sign right under the subtraction, and put 6.9..now what you do to one side, you have to do to the other. So add 6.9 to 3.18. Now once you did that, you have to add, but you can't add the 6.9 and the 6.9, you have to cross it out, but you HAVE to hadd 3.18 and 6.9..so do that. So for right now your answer should be: 4.8y = 10.08...let's finish solving! Now since there are two unlike terms, when it comes down to literally this, you have to divide each side by the number with the variable. So: 4.8y divided by 4.8...and 10.08 divided by 4.8.. now remember what I said..4.8y divided by 4.8 are alike so you have to cross it out. But you HAVE to divide 10.08 by 4.8. And once you do that..:::: y = 2.1 ....see? easy and simple!
