OpenStudy (miss.rose):

The first question is: Which word best describes the following math sentence? 5x + 4 = 24 A. Equation B. Inequality C. Absolute Value D. Expression Please help!

OpenStudy (pawanyadav):

As it contains sign of equality so its an equation.

OpenStudy (shiburinga):

Lol You can cross out C and B.

OpenStudy (shiburinga):

@Pawanyadav try to give them hints >.<

OpenStudy (pawanyadav):

Its everything

OpenStudy (shiburinga):

Now I cant ask hich you think it is... e.e

OpenStudy (shiburinga):

Next? :o

OpenStudy (miss.rose):

So its an equation? Next Question: Which lists all the integer solutions of the equation |x| = 10? A. –10 and 10 I think it is this one. But I'm open to learning. B. 10 only C. 0 and 10 D. -10 only

OpenStudy (shiburinga):

Yep :]

OpenStudy (pawanyadav):

You think absolutely right

OpenStudy (shiburinga):

Lool when it's like |x| it's always the opposite.. xP

OpenStudy (anonymous):

The first question is not b or d

OpenStudy (shiburinga):

Wait I got it backwards for #2 >.<

OpenStudy (shiburinga):

It's always non-negative.

OpenStudy (miss.rose):

Ready for the next question? Here it is: Which lists all the integer solutions of the inequality |x| < 4? A. -3, -2, -1, 0, 1, 2, and 3 This one? B. 0, 1, 2, and 3 C. 0, 1, 2, 3, and 4 D. -4, -3, -2 , -1, 0, 1, 2, 3, 4

OpenStudy (shiburinga):

It's definitley not D.. nor C.

OpenStudy (shiburinga):

Why do you think its A?

OpenStudy (miss.rose):

Because all of the numbers listed are less than 4.

OpenStudy (shiburinga):

Mhm.. but so is B. xD but because it has more numbers..? xP

OpenStudy (miss.rose):

Well, negative numbers can work in that equation.

OpenStudy (shiburinga):

Mhm. I agree with A. xP

OpenStudy (pawanyadav):

That was asking for all solutions so It's A

OpenStudy (shiburinga):

Mhm.

On July 1 there were 63 fish in the pond, which is 52 fewer fish than were in the pond on June 1. Which equation represents this situation? A. f + 63 = -52 B. 63 - f = 52 C. f + 63 = 52 D. f - 52 = 63 This one?

OpenStudy (shiburinga):
