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 ;-)

You could scale the axes just going by one

Walter is helping to make cookies for a basketball tournament. He's made 15 cookies so far. His coach asked him to make at least

seraphim [82]

Answer: First Option

Walter needs to make at least 5 more cookies but no more than 40

$5 \leq x \leq 40$

Step-by-step explanation:

If we call x the number of cookies that Walter needs to make, then we know that the amount of cookies will be:

$x +15$

Then this amount must be greater than or equal to 20 and must be less than or equal to 55 then.

$x + 15 \geq20$ and $x + 15 \leq55$

This is:

$20 \leq x + 15 \leq 55$

We solve the inequality for x.

$20-15 \leq x + 15-15 \leq 55-15\\\\5 \leq x \leq 40$

Then the amount of cookies that Walter must make must be greater than or equal to 5 and less than or equal to 40
