Hello there!

<u><em>Answer: ⇒⇒ $x=-\frac{1}{2}$ </em></u>

________________________________________________________________

Step-by-step explanation:

First you had to subtract by 3 from both sides of equation.

$6x+3-3=0-3$

Simplify.

$6x=-3$

Then you divide by 6 from both sides of equation.

$\frac{6x}{6}=\frac{-3}{6}$

Simplify.

$\frac{6x}{6}=x$

$\frac{-3}{6}=-\frac{1}{2}$

$x=-\frac{1}{2}$

Answer⇒⇒⇒⇒ $x=-\frac{1}{2}$

______________________________________________________________

Hope this helps!

Thank you for posting your question at here on brainly.

Have a great day!

The root of an equation f(x) is the x value(s) for which f(x) = 0.

So, if you have f(x) = 6x + 3, to find its root(s), you do 0 = 6x + 3, and then

0 - 3 = 6x + 3 - 3

-3 = 6x + 0

-3 = 6x

-3/6 = 6x/6

-1/2 = x

x = -1/2 is the one and only root (Linear functions will always have 0 or 1 root. They will have zero roots if they are horizontal lines of the form y = c, where c is any constant, and they will have one root if they are of the form y = mx + b, where m is not 0.)

81 is 37.5% of what number?

laila [671]

Hi,

81 is 37.5% of 216.

"1. We assume, that the number 37.5 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 37.5, so we can write it down as 100%=37.5.

4. We know, that x% equals 81 of the output value, so we can write it down as x%=81.

5. Now we have two simple equations:

1) 100%=37.5

2) x%=81

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=37.5/81

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81 is what percent of 37.5

100%/x%=37.5/81

(100/x)*x=(37.5/81)*x - we multiply both sides of the equation by x

100=0.46296296296296*x - we divide both sides of the equation by (0.46296296296296) to get x

100/0.46296296296296=x

216=x

x=216 "

Have a great day!

Two communication mask 2km apart and directly north and south of each other. Ubi 's home is 500 m from one and directly east. Ho

pochemuha

Answer: $2061.55\ m$

Step-by-step explanation:

Given

The two communication mask are 2 km apart

Ubi's home is 500 m east of one of the mask

Suppose its distance from the other's is x

From the figure, we can write

$\Rightarrow x^2=2000^2+500^2\\\Rightarrow x^2=4\times 10^6+25\times 10^4\\\Rightarrow x=2061.55\ m\ \text{or}\ 2.061\ km$

A study is designed to examine the effect of doing synchronized movements (such as marching in step or doing synchronized dance

Vlada [557]

Answer:

The complete question in the graphic

After synchronized exercise, it was observed that the average proximity rate has increased, which shows that the mean of the variable is positive and there is high synchronization in the groups.

If groups with low synchronization and high effort are compared, the result of the average will be positive, so the average proximity rate will also increase after the synchronization exercise is performed.

On the contrary, if we observe the groups that have low synchronization and low effort, the mean of the variable is negative, thus the average proximity rate after performing the exercise will decrease.

(C)

considering that the total degrees of freedom is 259, it will show 260 students in the analysis.

With a significance level of 5% or 0.05, the P value is less than the significance level, which leads to differentiating the mean of the scores before and after performing the combinations.

With a significance level of 1% or 0.01, the p-value is higher than the significance level. With this data we can conclude that there is no difference between the results before and after the synchronized exercise
