Answer:

x=3

PR=10

Step-by-step explanation:

This is an isosceles triangle, indicated by the black markers on angles P and Q. This also means that sides PR and QR are equal.

That in mind, to solve for x set the two expressions equal to each other and solve for x.

3x+1=5x-5 (subtract 1 from the left side and 5 from the right. Do the same from both sides)

-2x = -6 (divide by -2)

X=3

To find the measurement for PR, simply plug in the value for x into the equation for PR

3(3) +1

9+1 =10

Answer:

39 active volcanoes.

Step-by-step explanation:

Subtract 169 (whole) from 130 (part). 9 - 0 = 9, 6 - 3 = 3, and 1 - 1 = 0. Therefore, 169 - 130 = 39

Step-by-step explanation:

<u>Solution Of A System Of Equations </u>

A system of linear equations is given as

$\displaystyle \left\{\begin{matrix}ax+by=c\\ dx+ey=f\end{matrix}\right.$

There are many methods to solve them. We will use the method of reduction

The given system is

$\displaystyle \left\{\begin{matrix}2x+3y=45\\ x+y=10\end{matrix}\right.$

Multiplying the second equation by -3

$\displaystyle \left\{\begin{matrix}2x+3y=45\\ -3x-3y=-30\end{matrix}\right.$

Adding the resulting equations

$\displaystyle -x=15$

$\displaystyle x=-15$
