use the substituition method to solve the system of equation. choose the correct ordered pair 2x+y=8 y= -x+5

daser333 [38]

<u>Answer:</u>

Ordered pair = (3, 2)

<u>Step-by-step explanation:</u>

We are given the following equations and we are to solve them by substitution method:

$2x+y=8$ --- (1)

$y= -x+5$ --- (2)

Substituting the value of y from equation (2) to (1):

$2x+(-x+5) = 8$

$2x-x+5=8$

$x = 8-5$

x = 3

Substituting this value of x in equation (2):

$y = -(3)+5$

y = 2

So the ordered pair is (3, 2).

The triangles above are similar write a similarity statement if possible solve for x the images are not drawn to scale

e-lub [12.9K]

Answer:

The value of x is 8.

Step-by-step explanation:

In triangle PQR and XZY,

$\angle P=\angle X=90^{\circ}$

$\angle Q=\angle Z$

$\angle R=\angle Y$

By AA property of similarity, we can say that

$\triangle PQR\sim \triangle XZY$

The similarity statement is $\triangle PQR\sim \triangle XZY$ .

The corresponding sides of similar triangles are proportional. Since both triangles are similar, so

$\frac{PQ}{QR}=\frac{XZ}{ZY}$

$\frac{21}{28}=\frac{5x+2}{7x}$

$\frac{3}{4}=\frac{5x+2}{7x}$

$7x\times 3=(5x+2)\times 4$

$21x=20x+8$

$21x-20x=8$

$x=8$

Therefore the value of x is 8.

How to write 9/18 into a equivalent fraction

scoundrel [369]

There are many ways. $\frac{9}{18}$ is actually the same as $\frac{1}{2}$ so anything you do just has to have a numerator exactly half as the denominator. So one that would work is $\frac{18}{36}$ I just doubled both numbers. Other ones would be $\frac{5}{10} and \frac{6}{12}$ all of which the numerator is exactly half the denominator.
