Answer:

A) 12x - 4  and  B)  4(3x - 1)

Step-by-step explanation:

You have to combine like terms to solve this problem.   Any terms with the same variable are like terms, and all constants are like terms.

  4x - 6 + 8x  + 2          

   

          Here, 4x and 8x are like terms, so are -6 and 2, so we group them together

   4x + 8x - 6 + 2

Now simplify

     12x - 4             (4x + 8x = 12x, there are 4 'x's and you add 8 more 'x's,

                               you have -6 and add 2 to it).  This is answer A

Each of these terms has a multiple of 4, so we can factor that term out to get answer B

 4(3x - 1)             (12x/4 = 3x, and -4/4 = 1)

Answer:

A) 12x-4

and B) 4(3x-1)

Step-by-step explanation:

4x-6+8x+2

Rearrange the question

4x+8x-6+2

12x-4

B because when you simplify the equation 4(3x-1) = 12x-4

Serggg [28]

Answer:

B. x<27

Step-by-step explanation:

The shelter has 165 animals.

The shelter must keep its total occupancy below 300.

The shelter takes in an average of 5 animals per day. If x is the number of days, then in x days the shelter takes 5x animals. In total there will be

165+5x animals. This number must be less  than 300, so

165+5x< 300\\ \\5x< 300-165\\ \\5x< 135\\ \\x< 27

Y = -3x +10 3x +y = 5 substitution method
spayn [35]

Answer:

no solutions

Step-by-step explanation:

y = -3x +10

3x +y = 5

Substitute the first equation into the second equation

Let every instance of y in the second equation be replaced with -3x+10

3x+ (-3x+10) = 5

Combine like terms

10 =5

This is never true so there are no solutions

(These are parallel lines with the same slope but different y intercepts)
