The final answer is x = -19/6. The first step is to reduce the expression to
2/3 * 3(5-3x)= 29. This will make the equation much easier. The next step is to simplify by cancelling out the 3 in 2/3 with the 3 multiplying 5-3x so it leaves you with 2(5-3x)=29. Then you would remove the parenthesis by using the distributive property and simplifying 2(5-3x) to 10-6x= 29. Then subtract 10 from both sides, which leaves you with -6x = 19. Divide by -6 on both sides and you get x= -19/6. Hope this helps

Put the following equation of a line into slope-intercept form, simplifying all fractions.

Inessa [10]

Answer:

$y=\frac{3}{5} x-3$

Step-by-step explanation:

<u>Slope-intercept form:</u> y = mx+ b

m = slope

b = y-intercept

<u>Rearrange the equation:</u>

$-20y=-12x+60$

<u>Divide each side by -20:</u>

$\frac{-20y}{-20} =\frac{-12x}{-20} +\frac{60}{-20}$

$y=\frac{3}{5} x-3$

$y=\frac{3}{5} x-3$ is your simplified, slope-intercept form equation.

The width of a rectangle is 9 in. shorter than its length. The area of the rectangle is 252 in². What is the length of the recta

erastovalidia [21]

Answer:

the length of the rectangle is, 21 in.

Step-by-step explanation:

Area of the rectangle(A) is given by:

$A=lw$ .....[1]

where,

l is the length of the rectangle

w is the width of the rectangle.

As per the statement:

The width of a rectangle is 9 in. shorter than its length.

⇒ $w = l-9$

It is also given that:

The area of the rectangle is 252 in².

⇒A = 252 in².

Substitute in [1] we have;

$252 = l(l-9)$

⇒ $252 = l^2-9l$

⇒ $l^2-9l -252 = 0$

Factorize this equation:

Split the middle term;

⇒ $l^2-21l+12l-252=0$

⇒ $l(l-21)+12(l-21)=0$

⇒ $(l-21)(l+12)=0$

By zero product property we have;

$l-21 =0$ and $l+12 =0$

⇒ $l = 21$ and $l = -12$

Since, length cannot be in negative

⇒ $l = 21 in.$

Therefore, the length of the rectangle is, 21 inches.
