Answer:

108/43

Step-by-step explanation:

$(6\frac{2}{3}-\frac{2}{3}) : (\frac{8}{9}+1\frac{1}{2}) =$

$= 6 : (\frac{16}{18}+\frac{3}{2}) =$

$= 6 : (\frac{16}{18}+\frac{27}{18}) =$

$= 6 : (\frac{43}{18}) =$

$= 6 * \frac{18}{43} =$

$= \frac{108}{43}$

What ordered pair is a solution of the equation y-3=5(x-2)

RideAnS [48]

Answer:

(0,-7)

Step-by-step explanation:

In this question, we need to find an ordered pair of (x,y)

First we need to solve the equation for Y. It will be:

y-3=5(x-2)

y=5x-10 +3

y= 5x -7

Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be

y= 5x-7

y= 5(0) - 7

y=-7

The ordered pair will be: (0,-7)

If 14y - 4 = 24y + 26 , then 12y =

harkovskaia [24]

Solutions

To solve the equation we have to isolate 12y

$14y - 4 = 24y + 26

-4 - 26 = 24y - 14y

-30 = 10y

10y = -30

y =- -30/10

y = -3

12y =12/-3

12y = -36

Therefore, 12y = -36$

Write the equation of the line in fully simplified slope-intercept form.

fiasKO [112]

$y = -\frac{1}{2}x - 1$

Step-by-step explanation:

Let's pick two points on the line: $P_1(-4, 1)$ and $P_2(2, -2).$ Let's calculate the slope of this line using these points:

$m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}$

With this value of the slope, we can write the general slope-intercept form of the equation as

$y = -\frac{1}{2}x + b$

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

$-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1$

Therefore, the slope-intercept form of the equation is

$y = -\frac{1}{2}x - 1$

A 34-inch piece of wood is 2.4% of a longer piece of wood. How long is the longer piece of wood? Show your work. You can use pro

riadik2000 [5.3K]

Think of this as a proportion: 2.4 is to 100, as 34 is to L ("L" for "Long piece.")

Cross multiply to get 2.4 L = 3400, then divide both sides by 2.4 to be left with

L = 3400/2.4, so

L = 1416.666...

So the longer piece of wood is 1,416.66... inches long.

Hope this helps!!:)
