Please help!!<br><br> The solution of the equation is x = ?<br> .
LUCKY_DIMON [66]

Answer:

as below

Step-by-step explanation:

\frac{2}{7} = \frac{6x}{4x + 17}

2(4x + 17) = 7(6x)

8x +34 = 42x

34 = 42x-8x

34 = 34x

\frac{34}{34} = x

There are x number of students at helms. If the number of students increases by 7.8% each year, how many students will be there
vodomira [7]

There will be 1.078x students next year and equation is number of students in next year = x + 7.8% of x

<h3><u>Solution:</u></h3>

Given, There are "x" number of students at helms.  

The number of students increases by 7.8% each year which means if there "x" number of students in present year, then the number of students in next year will be x + 7.8% of x

Number of students in next year = number of students in present year + increased number of students.

\begin{array}{l}{\text { Number of students in next year }=x+7.8 \% \text { of } x} \\\\ {\text { Number of students in next year }=x\left(1+\frac{7.8}{100}\right)} \\\\ {\text { Number of students in next year }=x(1+0.078)=1.078 x}\end{array}

Thus there will be 1.078x students in next year

-3+3x=-2(x+1)<br> the 2 is a negative<br> please break it down
Veronika [31]
-3+3x=-2(x+1) First: I will get rid of the bracket:


-3+3x=-2x-2

Now, all the x goes to the left side, all the numbers without x to the right side:


3x+2x=-2+3

we add up"

5x=1

divide by 5:

x= \frac{1}{5}
