Mathematics

Lilit [14]4 years ago

Answer:

9

Step-by-step explanation:

-4(6x+3)= -12(x+10)

<u><em>Let's do the first part:</em></u>

-4(6x+3)

<em>**distribute**</em>

-4 x 6x = -24x; -4 x 3 = -12 ->>> -24x - 12

<u><em>Let's do the second part:</em></u>

-12(x+10)

<em>**distribute**</em>

-12 x x = -12x; -12 x 10 = -120 ->>> -12x -120

-24x -12 = -12x - 120

<em>**Move variable to the left-hand side and change its sign**</em>

-24x +12x -12 = -120

-12x - 12 = -120

-12x = 108

x = 108/-12

x=9

PLEASE ANSWER I HAVE 10 MINS!! What is the value of x? 1/6 (3-2x)&lt;1/3x
vfiekz [6]

Answer:

A

Step-by-step explanation:

Solve the inequality by simplifying the parenthesis with the distributive property. Then use inverse operations to isolate x.

1/6 (3-2x)<1/3x

1/6*3 - 1/6*2x < 1/3x

3/6 - 2/6x < 1/3x

1/2 - 1/3x < 1/3 x

1/2 < 1/3x + 1/3x

1/2 < 2/3x

1/2 * 3/2 < x

3/4 < x or x>3/4

Solve 5(8x-1)-x=2x+32 . solve step by step and explain each step please!!!!
alina1380 [7]

First, distribute the 5 into the 8x-1 (5 times 8x, 5 times -1)

40x - 5 - x = 2x + 32

Subtract the x

39x - 5 = 2x + 32

Switch the sides for -5 (it will become positive and add to the 32)

39x = 2x + 37

Switch sides for the 2x (it will become negative and subtract from the 39x)

37x = 37

Divide both sides by 37

x = 1
