Answer 2

Evaluate. Let \[z\] = 6



\[7z - 3z + 6\]
--------------
\[2z + (4z + 2)\]

Enter the answer in lowest terms.

[______}

_________

{_______]

Answer 3

The answer has to be in fraction form.

Answer 4

@sammixboo

Answer 5

Ok, so we have \(\color{red}{\dfrac{7x - 3z + 6}{2z+(4z + 2)}}\) right?

Answer 6

Right!

Answer 7

Ok, so if \(\color{red}{z=6}\), plug in 6 wherever z is

\(\color{red}{\dfrac{7\times6 - 3\times6 + 6}{2\times6+(4\times6 + 2)}}\)

Let's start with what's in the parenthesis, following the PEMDAS rules.

What is \(\color{red}{4\times6+2}\) ?

Answer 8

26

Answer 9

Right! SO now we have

\(\color{red}{\dfrac{7\times6 - 3\times6 + 6}{2\times6+26}}\)

Let's do all the multiplication in this whole fraction.
What is
7 x 6
3 x 6
and
2 x 6

Answer 10

Tag me when you reply =)

Answer 11

7 x 6 = 42

3 x 6 = 18

2 x 6 = 12

Answer 12

I've been tagging you so much today, I can remember your profile name.

Answer 13

sammixboo XD

Answer 14

Hehe :P

Anyways, that's correct! Let's plug them in. Right! SO now we have

\(\color{red}{\dfrac{42 - 18 + 6}{12+26}}\)

Whats 42 - 18 + 6 and 12 + 26?

Answer 15

18 and 38

Answer 16

38, correct, but not 18. Let's go over that. What is 42 - 18?

Answer 17

but...PEMDAS

Answer 18

PEMDAS

Parenthesis
Exponents
Multiplication OR Division (starting from left side of the expression/equation)
Addition OR Subtraction (starting from left side of the expression/equation)

Answer 19

Oh. Well that would've helped.

Answer 20

Hehe :)

Answer 21

Oh, it's 30, btw.

Answer 22

I used to do that a lot but learned after a while

Answer 23

Yeah! So now we have \(\color{red}{\dfrac{30}{38}}\) Do you know how to simplify that?

Answer 24

The easy way would be to divided by 2.

Answer 25

Right! So what is 30/2 and 38/2

Answer 26

I've memorized 30 divided by 2 by heart... ;) 15 and 19

Answer 27

=)

Right! So our final anser is 15/19

Answer 28

Whoa wait.

Answer 29

We should check that.

Answer 30

HmM?

Answer 31

actually, it seems that they're simplified.

Answer 32

hmm.

Answer 33

Yeah.

Answer 34

Hehe, 19 can't be divide by anything else except 1 and 19

Answer 35

I see.

Answer 36

=) I need to grab my glasses, give me a sec

Answer 37

Oh, you wear glasses too? It seems like vision problems are very common.

Answer 38
