Answer:

3 3/5 =x

3 .6 =x

Step-by-step explanation:

6/5 = x/3

Use cross products

6*3 = 5*x

18 = 5x

Divide each side by 5

18/5 = 5x/5

18/5 =x

3 3/5 =x

Answer: 3.6 = x

Step-by-step explanation: To solve for x in the given proportion, we simply use the means-extremes property which states the the product of the extremes, (6)(3), equals the product of the means, (5)(x).

So we have (6)(3) or 18 equals (5)(x) or 5x.

So we have the equation 18 = 5x.

Now dividing both sides by 5, <em>3.6 = x</em>.

Answer:

x = 18

A = 110

Step-by-step explanation:

Angles A and B are supplementary angles so they add to 180 degrees

A + B = 180

5x+20 + 9x -92 = 180

Combine like terms

14x -72 = 180

Add 72 to each side

14x-72+72 = 180+72

14x = 252

Divide each side by 14

14x/14 = 252/14

x =18

A = 5x+20

= 5*18 +20

=90 +20

= 110

Please answer this question

Free_Kalibri [48]

Answer:

Step-by-step explanation:

$log(3x^{3}) - log(x^{2}) = log(\frac{3x^{3}}{x^{2}})\\log(27) - log(x) = log(\frac{27}{x} )\\$

therefore,

$\frac{3x^{3} }{x^{2} } = \frac{27}{x} \\3x=\frac{27}{x} \\3x^{2} =27\\x= +3\\x=-3$

however, since logarithms cannot have negative arguments, x can only be +3

i.e. log(-3) is impossible, and will return MATH ERROR on a calculator.
