Which of the following equations could be used to determine the value of X

Tcecarenko [31]

Answer:

Step-by-step explanation:

If the original price is x and you deduct 3, you'l have x - 3.

If you buy 4 of them, you multiply that price by 4, giving you 4(x - 3).

Then, if that value is equal to 27, you get 4(x - 3) = 27

twelve and three tenths more than five and thirteen thousandths of a number d is equal to fifteen and three hundred two thousand

AVprozaik [17]

5.013d + 12.3 = 15.302
5.013d = 15.302 - 12.3
5.013d = 3.002
d = 3.002 / 5.013
d = 0.599 (thats rounded) <==

Find the missing segment in the attached image

xz_007 [3.2K]

Answer:

The length of the missing segment is 24

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

$\frac{15}{x} = \frac{15+5}{8+x}$

$\frac{15}{x} = \frac{20}{8+x}$

Cross Multiply

$15 * (8 + x) = 20 * x$

Open bracket

$15*8 + 15 * x = 20 * x$

$120 + 15x = 20x$

Subtract 15x from both sides

$120 + 15x -15x= 20x-15x$

$120 = 20x-15x$

$120 = 5x$

Divide both sides by 5

$\frac{120}{5} = \frac{5x}{5}$

$\frac{120}{5} = x$

$24 = x$

$x = 24$

Hence, the length of the missing segment is 24

(a-1)*(a+1) How does the expansion of this thing works?

kirill115 [55]

This is a simple formula:(a-b)*(a+b)= a^2-b^2
And it goes like this for your example: (a-1)*(a+1)=a*a+a-a-1*1=a^2-1^2=a^2-1
