Question

algebra II help on simplifying

Answer 1

They all look similar. Remember that you can directly manipulate the numerators if the denominator is the same.

i.e:
\[\frac{a + b - c + d}{g^2} + \frac{e}{g^2}\]
\[=\frac{a + b - c + d + e}{g^2}\]

Answer 2

I think it's B for the first question that is on top

Answer 3

Correct. :)

Answer 4

yay now for the one under it which is #3...

Answer 5

I think it might be C for that one

Answer 6

@tyteen4a03

Answer 7

@iappreciateyourhelp Nope. Try again!

Answer 8

D? @tyteen4a03

Answer 9

I'm not sure which one it is for this question @tyteen4a03

After you're done answering other questions please help.

Answer 10

@iappreciateyourhelp Nope.

Show your steps.

Answer 11

@tyteen4a03

Answer 12

@iappreciateyourhelp Take you time, verify what you are doing, and move on. Writing your steps out will help you realize what you did wrong.

Answer 13

@iappreciateyourhelp Are you answering the questions for them?

Answer 14

What do you mean? @tyteen4a03

Answer 15

After this math problem we're talking about I just have 2 more I need help on. All the rest I've done myself because they ask different things that I was able to do.

Answer 16

@iappreciateyourhelp These are 8th grade math questions, so I'm wondering, You can get your kids to write out the steps and show it here. :)

Answer 17

Oh no the ages of the kids I am currently watching are 5 years old, 1 years old and 3 years old...

Answer 18

I'm really running out of time to do this and I don't want my grade to get any lower.

Answer 19

@iappreciateyourhelp Ah. :)

A quicker hint: Simplify the upper parts, don't care about the factoring. What do you get?

Answer 20

It's B! I think... I really really think it's B because 4 + 5 = 9 and there's 9 in that one and the first two numbers equal out to 4. So is B correct?

Answer 21

@tyteen4a03

Answer 22

Correct. You'll eventually need to learn the correct way of doing this though. If there were 2 answers with the same numerator but different denominator you can't use this method - you'll be stuck.

Answer 23

Yeah you're right. I'll have to spend more time on figuring out how to properly get the answer when I am in the right place to do so. Thanks for helping. I just have two last ones and I'll be less stressed. Here is 5 and 6.

Answer 24

Here comes the hard ones. Do you know how to find the LCM (least common multiplier) of two terms?

Answer 25

Guessing won't help you with this one, you'll need to know how it works.

For 4, remember this: \(\frac{a}{b} + \frac{c}{d} = \frac{ad + bc}{bd}\). OpenStudy's COC prevents me from giving out the answer directly, but this is a pretty big hint.

Answer 26

I wish I could get the answer directly but I'm avoiding to ask that because it doesn't seem right to just ask you to give out the answers and I understand that about the COC. It's okay.

Answer 27

For 5, it's a little bit trickier. Just pick this up for now, you'll probably see how it works later:
\[\frac{a}{(b)(c)} + \frac{d}{c} = \frac{a + b(d)}{(b)(c)}\]
