it makes sense right?
17,416
22
[]
volunteer
as long as 2x<21, we can do the cutting
17,416
23
[]
volunteer
because the other dimension is wider
17,416
24
[]
student
okkkkk that makes sense
17,416
25
[]
volunteer
can you solve this inequality?
17,416
26
[]
student
being honest, probably not
17,416
27
[]
volunteer
how about this: can you solve the equation 2x = 21?
17,416
28
[]
student
is it 11?... or
17,416
29
[]
volunteer
how did you get it? you are very close
17,416
30
[]
student
I divided both sides by 2
17,416
31
[]
volunteer
well don. Sorry the inequality is the same
17,416
32
[]
volunteer
we want to isolate x on one side
17,416
33
[]
volunteer
to do that we divide both sides by 2
17,416
34
[]
student
so I got it right?
17,416
35
[]
volunteer
yes
17,416
36
[]
student
I'm cooking
17,416
37
[]
volunteer
yes you are
17,416
38
[]
volunteer
divide both sides by 2, we will get x< 10.5
17,416

student
thank u Mr. Mr. Davis for tutoring me I'll be sure to give you 5 stars
17,416

volunteer
can x be negative?
17,416
41
[]
volunteer
thank you
17,416
42
[]
student
no I don't think
17,416
43
[]
volunteer
so the domain will be (0, 10.5)
17,416
44
[]
volunteer
does that make sense?
17,416
45
[]
student
yes bc none our numbers are negative right?
17,416

yes

Hello, Alex! What can I help you with?

[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 7, "end": 11 } ]
student
I need help with a percentage problem
17,429
2
[]
volunteer
Of course!
17,429
3
[]
volunteer
Could you paste the problem on the white board or put it in the chat?
17,429
4
[]
student
I need to find the discounted price without subtracting the discounted price with the original
17,429
5
[]
volunteer
Okay! If you could send through the exact question that would be very helpful. We can work through it together!
17,429
6
[]
volunteer
Alright, just give me one second to work through the problem!
17,429
7
[]
student
Ok
17,429
8
[]
volunteer
Okay, just to be clear, you need to explain the process of solving this problem?
17,429

[]
volunteer
Alex, are you there?
17,429

[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 0, "end": 4 } ]
student
Yes
17,429
11
[]
student
Yes I need to explain the process of solving this
17,429
12
[]
student
Without using subtraction
17,429
13
[]
volunteer
Alright, perfect!
17,429
14
[]
volunteer
So, you're first sentence looks good. We need to confirm that $12 is 100% of the price.
17,429
15
[]
volunteer
Now, instead of using subtraction to solve this, here's what we can do: First, tell me, what 100% - 15%?
17,429
16
[]
student
85%
17,429
17
[]
volunteer
Perfect!
17,429
18
[]
volunteer
Therefore, we know that taking 15% away from $12 is the SAME as finding 85% of $12.
17,429
19
[]
volunteer
Does this make sense?
17,429
20
[]
student
Yes
17,429
21
[]
volunteer
Perfect!
17,429
22
[]
volunteer
So, we just need to find 85% of 12. Do you know how to do that?
17,429
23
[]
student
Multiply 0.85 with 12
17,429
24
[]
volunteer
Yup! Tell me what you get!
17,429
25
[]
student
I got 10.20
17,429
26
[]
volunteer
That's the correct answer! $10.20!
17,429
27
[]
volunteer
Are you able to explain the process we just did, or do you need some help?
17,429
28
[]
student
First, subtract 15% from 100%, which is 85%, then, I find 85% % by multiplying 0.85 with 12. That would lead to 10.20, which is the answer
17,429

[]
volunteer
Beautiful explanation!
17,429

You're all done!
17,429

Do you need anymore help before I end the session?
17,429

Nah, i think i might be good

[]
student
i am very confused with this
17,426
2
[]
volunteer
I see the problem
17,426
3
[]
volunteer
DW it's simple
17,426
4
[]
student
ok
17,426
5
[]
volunteer
You know how to expand (a+b)^2
17,426
6
[]
volunteer
?
17,426
7
[]
student
no
17,426
8
[]
student
i am not sure
17,426
9
[]
volunteer
Okay it's simple
17,426
10
[]
volunteer
We use foil to expand the expression
17,426
11
[]
volunteer
That means First, Outside, Inside, Last
17,426
12
[]
volunteer
Wanna try?
17,426
13
[]
student
ok
17,426
14
[]
student
its says a+b
17,426
15
[]
student
so how would i expand this expression
17,426
16
[]
student
ohh
17,426
17
[]
volunteer
Now you wanna try? :)
17,426
18
[]
volunteer
This will be useful for solving the problem
17,426
19
[]
student
then b b?
17,426
20
[]
volunteer
Yes, but not yet
17,426
21
[]
volunteer
What is a*b?
17,426
22
[]
student
ohh ok
17,426
23
[]
volunteer
Wanna solve it now?
17,426
24
[]
volunteer
Oh, and here's a hint
17,426
25
[]
volunteer
I'll give you some time to solve it, okay?
17,426
26
[]
student
ok
17,426
27
[]
student
your asking how to simplify it?
17,426
28
[]
volunteer
We want to find out what (5+i)^2 is, and given that (a+b)^2 and i^2=-1
17,426
29
[]
volunteer
I'll give until 4:30 to figure it out
17,426
30
[]
volunteer
And if you still need help, I'll walk you through it
17,426
31
[]
volunteer
ok?
17,426
32
[]
student
ok
17,426
