Rearrange items :

2+6x=1 - x

6x + 2 = 1 - x

Answer should be : x = - 1/7 or - 1/7

Lexi subtracts 9,405 from 11,138 should her answer be greater than or less than 2,000

sergey [27]

Less than because if you subtract 11, 138 minus 9,405 you get the answer you get 1,733 and that is less than 2,000

If 6:2=8:x, then a. 6x = 16 b. 6x = 10 c. 2x = 48 d. 2x = 14

stellarik [79]

Answer:

6x = 16

Step-by-step explanation:

Given:

$\displaystyle \large{6:2 = 8:x}$

The equation can be rewritten as:

$\displaystyle \large{\dfrac{6}{2}=\dfrac{8}{x}}$

Multiply both sides by 2x.

$\displaystyle \large{\dfrac{6}{2}\cdot 2x=\dfrac{8}{x}\cdot 2x}$

Simplify the equation in simplest form.

$\displaystyle \large{6x=8\cdot 2}\\\\\displaystyle \large{6x=16}$

Therefore, the answer to this question is 6x = 16.

AB lies on a number line. The coordinate of point A is -6. Given that AB=20, what are two possible coordinates for point B?

Dafna1 [17]

Answer:

-26 or 14

Step-by-step explanation:

Given that

Coordinate of point A is -6.

Length of AB = 20

To find:

Coordinates for the point B = ?

Solution:

We are given that:

AB = 20

In other words, we can use modulus function to define the distance between A and B:

|Coordinates of B - Coordinates of A| = 20

Let the coordinates of B = $x$

Kindly refer to the attached image for the given situation.

Point B might be either on the left or on the right side of A.

That means:

$|x-(-6)| = 20\\\Rightarrow |x+6|=20$

Now, let us have a look at the modulus function:

$|y|=\left \{ {-{y}\ if\ y0} \right.$

So,

$|x+6|=\left \{ {-{(x+6)}\ if\ (x+6)0} \right.$

$(x+6 ) =20\\\Rightarrow x =14$

$-(x+6 ) =20\\\Rightarrow x =-26$

Therefore, the answer is:

-26 or 14
