What is x/9 = 9/27 help plz

Irina18 [472]

<h3>QUESTION: </h3>

what is x/9 = 9/27 help plz

<h3>ANSWER AND SOLUTION: </h3>

SOLVING FOR X

Reduce first the fraction with 9

$\large \sf = \dfrac{x}{9} = \dfrac{ \cancel9}{ \cancel{27}}$

 $\large \sf = \dfrac{x}{9} = \dfrac{1}{3}$ 

Now simplify using cross-multiply

 $\large \sf = \dfrac{3x}{9} = 1$ 

 $\large \sf = 3x = 1 \times 9$ 

 $\large \sf = 3x = 9$ 

Lastly divide both sides

 $\large \sf = 3x \div 3 = 9 \div 3$ 

 $\large \sf = x = 9 \div 3$ 

 $\large \sf = x = 3$ 

<h3>FINAL ANSWER:</h3>

$\huge \orange{ \underline{ \boxed{ \sf{x = 3}}}}$

HOPE THIS HELP YOU! HAVE A NICE DAY!

Write the equation of a line that is perpendicular to y =3x-2 and that passes through the point(-9,5)

Oduvanchick [21]

Answer:

y = -1/3x + 8

Step-by-step explanation:

If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.

(basically if one is say -2/3, the other is 3/2. just flip it upside down)

So this slope is 3, so the new slope should be -1/3

The equation is now y = -1/3x + b

To find b, substitute (-9,5) in the equation

y = -1/3x + b

5 = -1/3(9) + b

5 = -3 + b

8 = b

So the equation is y = -1/3x + b
