First, solve the parenthesis by multiplying the numbers in and out of them:

2+6x-12=12x-6

Next, put them in order so you can solve the equation:

2-12+6=-6x+12x

Next solve:

-4=6x

So x is:

-6/4

So C is the correct answer,

Hopefully, this helps you find the answer! If it doesn't, tell me in the space below and I'll solve it completely

This is the same as:
6x-10=12x-6
-4=6x
x=-2/3

So statement c is true.

After reading 80\%80% of her e-mails in her inbox, Danette still has MM unread e-mails.

NARA [144]

Answer: The correct options are.....

A) $\frac{M}{1-0.8}$ and

B) $5M$

Step-by-step explanation:

Suppose, the number of e-mails Danette had in her inbox before she started reading was $X$ .

Percentage of read emails is 80%, so the number of read emails $= (\frac{80}{100}*X)=0.8X$

Thus, the number of unread emails $= X-0.8X=X(1-0.8)$ , which is given as $M$ .

So, the equation will be........

$X(1-0.8)=M\\ \\ \Rightarrow X=\frac{M}{1-0.8} (Answer: 1) \\ \\ \Rightarrow X=\frac{M}{0.2}\\ \\ \Rightarrow X=(\frac{1}{0.2})M=5M (Answer: 2)$

Thus, the expressions which could represent the number of e-mails Danette had in her inbox before she started reading are: $\frac{M}{1-0.8}$ or $5M$

a rectangular room is three times as long as it is wide and it's perimeter is 64 meters. find the width of the room

Solnce55 [7]

Length = 3x
width = x
perimeter = 2* (3x+x)
equation:
2*(3x+x)=64
2*4x=64
8x=64
x=64/8 = 8 (thats width in meters)
