What have you learned so far in algebra 1?
anonymous
  • anonymous
Equations, solving them, adding and subtracting integers, inequalities, word problems (I suck retriceat those) linear function, and absolute value
4everaddicted2anime
  • 4everaddicted2anime
What kind of equations? Just linear?

Linear, finding slope, distributing stuff order of operations and yeah

I'm not sure if I remember most of the terms I told you about
4everaddicted2anime
  • 4everaddicted2anime
Okay. I'm going to come up with some equations for you to try. I'll help you with anything you can't remember.

Here is what I've come up with so far 1. -8-4 2. 10-(-9) 3. 20+(-30) 4. 100+(-15) 5. 4(5-2)+10((1/2)+1) 6. (5+6)/(2*6-1) 7. 21-2(4+5) 8. 16(5)+(-11)+10

1.-12 2.-90 3.-600 4.-1500 5. Idk :( 6.idk 7.8+10*21-2=342 8. Idk
anonymous
  • anonymous
Is this on all the subjects that I've told you about? Or some of it?
4everaddicted2anime
  • 4everaddicted2anime
Just some of it
anonymous
  • anonymous
Oh. Mkaye

2. 10-(-9) The parenthesis around the negative nine are just there to separate the two minus symbols. The word form of it would be ten minus negative nine. The two negatives would cancel each other out and make it 10+9 which equals 19.

So you don't have to distribute if it looks like that
4everaddicted2anime
  • 4everaddicted2anime
In this case, no
4everaddicted2anime
  • 4everaddicted2anime
The same thing with the parenthesis goes with numbers 3 and 4 too. So #3 would be 20-30 which equals -10. #4 would be 100-15 which would be 85.
anonymous
  • anonymous
Oh
4everaddicted2anime
  • 4everaddicted2anime
#5. 4(5-2)+10((1/2)+1) First you wpuld need to do the stuff in the parenthesis 4(3)+10(1.5) Then you multiply 12+15 Finally you add to get 27
anonymous
  • anonymous
Where did you get the 15? Wouldn't that be some decimal?
4everaddicted2anime
  • 4everaddicted2anime
#6. (5+6)/(2*6-1) Okay. To make this easier lwts split up the numerator and the denominator. The numerator is 5+6. The denominator is 2*6-1. Lets work out the numerator first. 5+6=11 Next, lets work out the denominator. 2*6-1 2*6=12 12-1=11 Now lets put our answers for the numerator and denominator back into the fractional form It turns out to be 11/11 when you divide the numerator and denominator you get an answer of 1.

  • 4everaddicted2anime
I got 15 from multiplying 10 and 1.5
anonymous
  • anonymous
Oh okay yeah ur right
4everaddicted2anime
  • 4everaddicted2anime
#7. 21-2(4+5) First you do yhe stuff in the parenthesis 21-2(9) Then you multiply 21-18 Finally you subtract these to get 3
anonymous
  • anonymous
Okay :)
4everaddicted2anime
  • 4everaddicted2anime
#8. 16*5+(-11)+10 First you multiply 80+(-11)+10 Next you subtract 80 and 11 69+10 Finally you add to get 79
anonymous
  • anonymous
So do you have to multiply 16 and five before distributing the 11? Or no..
4everaddicted2anime
  • 4everaddicted2anime
Yes to the first part. You do multiply 16 and 5 first. The parenthesis around the -11 are only there to separate the + and the -.
4everaddicted2anime
  • 4everaddicted2anime
The next four questions are about finding the linear equation 9. (-4,-7)(8,-13) 10. (-1,3) m=3 11. (1,8)(-2,-1) 12. (-4,-1)(2,2)
