Which value for x makes the following number sentence true? 12x = 6x + 24

To solve this, first subtract 6x from both sides.

That is because there cannot be the same variable on both sides of the equation. The new equation would be:

6x=24

Now divide by both sides of the equation by 6

x=4

Hope this helped! Tell me if you have any more questions!

a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the r

Oxana [17]

Answer:

A. x²/y³

Step-by-step explanation:

Given the following data;

Length = x³y⁴

Width = $xy^{7}$

Ratio = length/width

$Ratio = \frac{x^{3}y^{4}}{xy{^7}}$

Simplifying the equation by applying the law of indices (division), we have;

$\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2}$

$\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3}$

Hence, rearranging the above values;

$Ratio = \frac{x^{2}}{y^{3}}$

<em>Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³. </em>

Write the equation of the line that passes through the given points<br> (0,2)) and (-9, -3)

Irina18 [472]

Step-by-step explanation:

Y= m x+ C

m (slope ) = 2 - (_3) / 0 _( - 9 )

= 5 / 9

( O, 2 ) Satisfying equation

2= 5/9 ( 0) + C

C= 2

So eq. is

y= 5/ 9 X + 2
