X=6 you have to plug into x so:
2(.5(6)-3)=0
2(3-3)=0
2(0)=0

Answer:

x = 6

Step-by-step explanation:

2(0.5x−3)=0

<u>Distribute</u>

1x-6=0

<u>Push the constant to the other side</u>

1x-6=0

 +6 +6

1x=3

<u>Divide both sides by 1</u> (Optional, this does not even need to be a step)

1x/1 = 6/1

x = 6

Im cold n tired just gimme the answer dont play with me:/
enyata [817]

Answer:

A) y = 3x + 2 y = -2x + 5

Step-by-step explanation:

We can rule out options B and D right away, because one of the lines' y-intercept is positive 2 not negative.

(Remember that y-intercept is the b in y=mx+b).

So at this point we know the answer is either A or C.

We can also rule out C though, because the second line's y-intercept is positive 5, while the second line in option C is negative.

You can also use the slope of each line to double check.

Hope this helps :)

Also please mark me brainliest, I'm almost there to the next rank.

I typically give 12% of money I receive to my church. My uncle died recently and left me some money. I donated $408 to my church
sweet [91]

your uncle left you with "x" total, which is the 100%, now, we also know that 408 is 12% of that, so

\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 408& 12 \end{array} \implies \cfrac{x}{408}=\cfrac{100}{12}\implies \cfrac{x}{408}=\cfrac{25}{3} \\\\\\ 3x=10200\implies x=\cfrac{10200}{3}\implies x=3400
