A. 17
B. 13
C. 7
D. 1

Answer 1

That would become 8/2-32+3(8-3), do you know how to solve it from there?

Answer 2

@flamingpiano No...still confused on it.

Answer 3

i'll help

Answer 4

they have already provided the given value so we just need to plug it in

Answer 5

hold on one sec

Answer 6

@LGumboymath234 im still confused on the answer tho.

Answer 7

Here, let's go one step further. 8/2-32+3(8-3), take the (8-3)=5, then you do 5*3, giving you 15. So now you have 8/2-32+15.

Answer 8

Now you divide 8/2, giving you 4-32+15, can you do that?

Answer 9

-13

Answer 10

Yep.

Answer 11

so -13 is the correct answer?

Answer 12

@karamarie02 , I messed up somewhere that made it -, do you know where?

Answer 13

@LGumboymath234 , Do you know where the mistake is?

Answer 14

no

Answer 15

Hmm, I just worked it out again, it gave me -13 in a calculator. Maybe it wants you to multiply by -1 to give you 13?

Answer 16

So I'd say it'd have to be B. 13

Answer 17

okay... Can you help me with one ore question? @LGumboymath234 and @flamingpiano

Answer 18

Sure.

Answer 19

What is when n = 8?

Answer 20

Is there an equation? All I see is "What is when n = 8?"

Answer 21

wait one second please.

Answer 22

What is (n-5) x 6 / n divided by 4 when n = 8?

Answer 23

It would simplify to (8-5)*6/8, then to 3*6/8 giving you 2.25.

Answer 24

thankyou!!!!!!

Answer 25

You're welcome.
