X+2y=10
2x+8y=16

x=-2y+10

2x+8y=16
2(-2y+10)+8y=16
-4y+20+8y=16
4y=-4
y=-1

x=-2y+10
x=-2(-1)+10
x=2+10
x=12

This means that there can be only one solution (12,-1).

What is mKNL?<br> Enter your answer in the box.

sergejj [24]

Answer:

102°

Step-by-step explanation:

As the vertically opposite angles are equal,

$5x+2={3(x+14)$

Now let's solve for x now

$5x+2=3(x+14)\\$

$5x+2=3x+42$

$5x-3x=42-2$

$2x=40$

$\frac{2x}{2} =\frac{40}{2}$

$x=20 \\$

Now let's find the value of KNL

$3(x+14)\\3(20+14)\\3*34\\102$

Hope this helps you.

Let me know if you have any other questions ;-)

$\frac{5}{7} \times \frac{3}{8} = \frac{15}{32}$

➢

$\frac{4}{8} \times \frac{1}{4} = \frac{1}{8}$

➢

$2 \frac{1}{2} \times 3 \frac{2}{5} = 8 \frac{1}{2}$

$\frac{8}{14} \times \frac{1}{2} = \frac{2}{7}$

➢

$\frac{3}{4} \div \frac{1}{4} = 3$

➢

$1 \frac{2}{3} \div 2 \frac{3}{5} = \frac{25}{39}$
