483.6 is what percent of 180
liraira [26]

Answer:

We assume, that the number 180 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 180, so we can write it down as 100%=180.

4. We know, that x% equals 483.6 of the output value, so we can write it down as x%=483.6.

5. Now we have two simple equations:

1) 100%=180

2) x%=483.6

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%=180/483.6

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

7. Solution for 483.6 is what percent of 180

100%/x%=180/483.6

(100/x)*x=(180/483.6)*x       - we multiply both sides of the equation by x

100=0.37220843672457*x       - we divide both sides of the equation by (0.37220843672457) to get x

100/0.37220843672457=x

268.66666666667=x

x=268.66666666667

now we have:

483.6 is 268.66666666667% of 180

What is the equation for the values in the table
devlian [24]

Step-by-step explanation:

Taking any two points through which the line passes;(-10,-3) and (-5,-1)

The equation of the line is given by

\frac{y2 - y1}{x2 - x1}  =  \frac{y - y1}{x - x1}

=>  \frac{ - 1 - ( - 3)}{ - 5 - ( - 10)}  =  \frac{y - ( - 3)}{x -  ( - 10)}  =  \frac{y + 3}{x + 10}

=>  \frac{ - 1 + 3}{ - 5 + 10}  =  \frac{y + 3}{x + 10}

=>  \frac{2}{5}  =  \frac{y + 3}{x + 10}

=> 5(y + 3) = 2(x + 10)

=> 5y+15 = 2x+20

=> 5y =2x+5

=> y= \frac{2}{5} x + 1

Solve: 2x + 18 - 1 = 33
Alecsey [184]

Answer: x=8

<u>Simplify both sides of the equation</u>

<u />2x+18+-1=33<u />

<u />(2x)+(18+-1)=33(Combine Like Terms)

2x+17=33

<u>Subtract 17 from both sides</u>

<u></u>2x+17-17=33-17\\2x=16<u></u>

<u></u>

<u>Divide both sides by 2</u>

<u></u>2x/2=16/2\\x=8<u></u>
