Answer:

y = - $\frac{12}{5}$

Step-by-step explanation:

Given

3x - 5y = 15 ← substitute x = 1 into the equation

3(1) - 5y = 15

3 - 5y = 15 ( subtract 3 from both sides )

- 5y = 12 ( divide both sides by - 5 )

y = - $\frac{12}{5}$

Between what two integers is √95?

andrey2020 [161]

Answer:

Between 9 and 10.

Step-by-step explanation:

We know that √81 = 9 and that √100 = 10.

Since √95 is between √81 and √100, we know it will be between 9 and 10.

√95 = 9.74679

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 ;-)
