\text{Hey there!}

\mathsf{Solve: 6 -x- x=18}

\mathsf{Combine\ your\ like\ terms}\\\mathsf{6 -\bf{x - x}\mathsf{= 18}}\\\mathsf{-x-x=-2x}\\\mathsf{Your\ new\ equation: -2x+6=18}\\\\\mathsf{Do\ the\ OPPOSITE\ symbol\ on\ both\ sides\ of\ the\ equation}\\\mathsf{Addition\ opposite\ symbol\ is\ subtraction}\\\mathsf{Subtract\ by\ 6\ on\ your\ sides}\\\mathsf{-2x+6-6=18-6}\\\mathsf{Cancel\ out{6-6\ because\ it\ gives\ us\ 0}}\\\mathsf{Keep:18-6\ because\ it\ helps\ us\solve\ for\ the\ answer}\\\\\mathsf{Next,\ divide\ both\ sides\ by\ -2}

\mathsf{\dfrac{-2x}{-2}=\dfrac{12}{-2}}\\\\\mathsf{Cancel\ out: \dfrac{-2x}{-2}\  because\ it\ gives\ you\ the\ result\ of 1}\\\\\mathsf{Keep:\dfrac{12}{-2}\ because\ it\ gives\ the\ answer\ of\ x}\\\\\\\boxed{\bf{Answer:\mathsf{x=-6}}}}}}}\checkmark

mario62 [17]

Answer:

The chemical element loses 4% of its weight everyday

Step-by-step explanation:

Here, we are interested in knowing the percentage weight loss of the chemical each day.

The key to answering this is looking at the expression inside the bracket.

We can express M(t) = 169•(0.96)^t as

M(t) = 169•(1-0.04)^t

So what this means is that we need to find the percentage value corresponding to 0.04 since it is a constant term here

Mathematically, 0.04 is same as 4/100, so we can clearly say that the constant percentage loss is 4%

Does anyone know how to do this?
Tom [10]

Answer:

look below but sorry that i dont know part b

Step-by-step explanation:

y = 5/2x-3

slope=5/2 y-int = -3

y=x-9

slope=1/1 y-int=-9

y=5x

slope= 5/1 y int=0

y=-1/2x +5

slope=-1/2 y-int= 5

plzzzz plzplz mark me brainliest thank you!!!!!!!!!!!!

If you had a rubik's cube with 10 little squares on each side, and peeled off the outer layer, how many little cubes would you e
Pachacha [2.7K]
There is 6 sides in a cube, multiplying we get the number of squares:
6*10 = 60 little squares. 
Peeling off one layer means subtracting 10 squares from the above numbers like this:
60 - 10 = 50. 

Answer: we end up with 50 littles squares.

​ Quadrilateral ABCD ​ is inscribed in this circle.
Sunny_sXe [5.5K]

Answer: m\angle A=116\°

Step-by-step explanation:

The missing figure is attached.

For this exercise it is important to remember that, by definition, the opposite interior angles of an inscribed quadrilateral are supplementary, which means that their sum is 180 degrees.

Based on this, you can identify that the angle D and the angle B are opposite and, therefore, supplementary.

Knowing that, you can write the following equation:

x+28\°=180\°

Now you must solve for "x" in order to find its value. This is:

x=180\°-28\°\\\\x=152\°

Then:

m\angle D=152\°

You know that:

m\angle A=(x-36)\°

Therefore, since you know the value of "x", you can substitute it into   m\angle A=(x-36)\° and then you must evaluate, in order to find the measure of the angle A. This is:

 m\angle A=152\°-36\°\\\\m\angle A=116\°
