3x-11=-1x-75<br> find the x value that would make this equation true

Tju [1.3M]

3x - 11 = -1x -75
3x = -1x -75 +11
3x + 1x = -75 + 11
4x = -64
x = -64/4
x = -16

Complete Question

The complete question is shown on the first uploaded image

Answer:

The balanced chemical equation of a bi molecular elementary reaction that would complete the proposed mechanism is

$CH2CH2Cl^+ (g) + Cl^- (g) ---> CH2CH2Cl2$

Step-by-step explanation:

The reason the reaction above is is the reasonable second step is that it both involves carbonation and Cl⁻ species abd hence it is bi molecular in nature.

The area on a wall covered by a rectangular poster is 486 square inches. The length of the poster is 1.5 times longer than the w

Anna11 [10]

Answer:

Step-by-step explanation:

If the length and width of the poster are represented by variables $l$ and $w$ respectively, then we can set up the following equations based on the problem statement:

$lw = 486$

$l = 1.5w$

We can plug the second equation in the first to get the following:

$(1.5w)w = 486$

$1.5w^{2} = 486$

$w^{2} = 324$

$w = 18$

Plugging this back into the first original equation, we can get the value of $l$ :

$l(18) = 486$

$l = 27$

From this, we know that the width is $18$ units and the length is $27$ units.
