Answer 1

@kelliegirl33 holy cow... wtf are you writing! a 20 paragraph essay..

Answer 2

2x - 10y + 3x^2 + 7y - 10x
combine like terms :
3x^2 -- there is no other like term with this
2x - 10x = -8x
-10y + 7y = -3y
now put it all together..
3x^2 - 8x - 3y
================
32 + (7 - 2) * 4 - 6/3
32 + 5 * 4 - 6/3
32 + 20 - 2
52 - 2 = 50 ...oops, that is not an answer choice

Does this problem have any more parenthesis in it ?

sorry it is taking so long...I am kinda stuck on your second question

Answer 3

No, number 2 is just 3^2+(7-2)x4-6 over three
Or 6/3

Answer 4

I am sorry...I can't seem to get any of your answer choices for the 2nd one

Answer 5

I can't either..

Answer 6

32 + (7 - 2) • 4 - 6 over 3

\(\displaystyle \frac{32+(7-2)\times4-6}{3}\)

\(\displaystyle \frac{32+(5)\times4-6}{3}\)

\(\displaystyle \frac{32+20-6}{3}\)

\(\displaystyle \frac{46}{3}\)

This is what I get.

Answer 7

No, its just 6 over 3 like 6/3
Not the whole equation

Answer 8

Ahhh, that makes a difference.

\(\displaystyle 32+(7−2)×4+\frac{6}{3}\)

\(\displaystyle 32+(5)×4+2\)

\(\displaystyle 32+20+2\)

\(54\)

Answer 9

I got 46/3 as one of my answers also...that is not an answer choice

Answer 10

Yeah, like that.. Thank you Austin ! Do you guys mind helping me with a couple more ?
This isn't a test btw, its just a review.

Answer 11

sure, why not :)

Answer 12

wait...it says *4 - 6/3

Answer 13

oh yeah its - not + ...

Answer 14

Then what the deuce.... there must be an error in the question then.

Answer 15

I keep getting different answers of which none are the answer choices

Answer 16

its 4-6/3
Not 4+6/3

Answer 17

It has to be the second one though, it must just be an error. Because if you do that you actually get an answer.

Answer 18

I kept getting 50 as my answer...lol

Answer 19

I keep getting 42 ...

Answer 20

According to your given expression, following order of operations (PEMDAS) it should be 50. But I am of the opinion that there is an error in the question. Not by you @lexis98 but more likely the book or site or wherever you got this question.

Answer 21

I am going to agree with austin...none of my answers are your answer choices

Answer 22

It's a question on my flvs review practice test.
I wrote it just like it gave me.

Answer 23

Oh well... I'll go with 54!

Answer 24

Question 6
A truck is rented at $40 per day plus a charge per mile of use. The truck traveled 15 miles in one day and the total charge was $115. Which equation can be used to find the charge x, in dollars, per mile traveled?
A. 40x + 15 = 115
B. 40 + 15x = 115
C. 40x + 15x = 115
D. 40 + 15 = 115x

Question 11
Which of the following is the most appropriate unit to describe the rate at which data is transferred using the internet?
A. Megabits per second, because the independent quantity is time in seconds and dependent quantity is amount of data in megabits.
B. Seconds per megabit, because the independent quantity is time in seconds and dependent quantity is amount of data in megabits.
C. Seconds per megabit, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds.

D. Megabits per second, because the independent quantity is amount of data in megabits and dependent quantity is time in seconds.

Answer 25

Ok, for question 6 we have this basic formula.

\(P=dx+40\)
Where,
P=price
d=distance
x=price/mile
40 is the flat fee.

Do you see anything that fits that?

Answer 26

These are the answers
40x + 15 = 115
40 + 15x = 115
40x + 15x = 115
40 + 15 = 115x

Answer 27

Is there one that seems to fit my form from the information given?

Answer 28

40 + 15x = 115 ?

Answer 29

I would agree :)

Answer 30

Okay, now number 11.

Answer 31

Ok, how would you narrow it down here? You should be able to narrow it down to 2 answer choices.

Answer 32

A and D?
