Answer:

x = 17

y = 8

QPR = 35º

QRP = 60º

Step-by-step explanation:

2x + 1 = x + 18

Subtract x from both sides

x + 1 = 18

Subtract 1 from both sides

x = 17

QPR = 2x + 1

QPR = 2(17) + 1

QPR = 35º

-------------------------------

8y - 4 = 4y + 28

Subtract 4y from both sides

4y - 4 = 28

Add 4 to both sides

4y = 32

Divide both sides by 4

y = 8

QPR = 8y - 4

QRP = 8(8) - 4

QRP = 60º

Answer:

$\frac{3}{2}$

Step-by-step explanation:

$[\frac{2}{5}-\frac{3}{10}+(3-1)]\div 1\frac{2}{5}\\\\=(\frac{4}{10}-\frac{3}{10}+2)\div\frac{5+2}{5}\\\\=(\frac{1}{10}+2)\div \frac{7}{5}\\\\=(\frac{2\cdot10+1}{10})\div \frac{7}{5}\\\\=\frac{21}{10}\div \frac{7}{5}\\\\=\frac{21}{10}\times \frac{5}{7}\\\\=\frac{21\cdot5}{10\cdot7}\\\\=\frac{3}{2}$

In the elimination method one variable is eliminated from the system of equation to find the value of other.

The first equation must be multiplied by 18 and second equation must be multiplied by 8.

<h3>What is elimination method?</h3>

To solve the system of equation and find the value of the variables, the elimination method is used.

In this method one variable is eliminated from the system of equation to find the value of other.

Given information-

The system of equation given in the problem is,

$\dfrac{1}{4}x -\dfrac{1}{6}y =5\\$ ......1

Let the above equation as equation 1.

The second equation given in the problem is,

$\dfrac{4}{5}x +\dfrac{3}{8}y =10$ ......2

Let the above equation as equation 2.

To eliminate the y term, make the coefficient of <em>y</em> of both the equation equal.

As the coefficient of <em>y</em> of the equation 2 is 3/8. Thus multiply second equation with 8 to eliminate coefficient. Thus,

$8\times \dfrac{4}{5}x +8\times\dfrac{3}{8}y =8\times10\\$

$\dfrac{32}{5}x +3y =80$ .....3

Multiply equation 1 with 18 to make the coefficient of y equal. Thus,

$18 \times\dfrac{1}{4}x -18\times\dfrac{1}{6} \times y =18 \times5$

$\dfrac{18}{4}x -3 =90$ ......4

Add equation 3 and equation 4 as,

$\dfrac{32}{5}x +3y+ \dfrac{18}{4}x -3y =80+90$

$\dfrac{32}{5}x + \dfrac{18}{4}x =170$

Hence the first equation must be multiplied by 18 and second equation must be multiplied by 8.
