Mark has 312 books in his bookcases. He has 11 times as many fiction as nonfiction books. How many fiction books does Mark have?
larisa [96]
11x represents the fiction
X represents the nonfiction book

11x+x=312
12x=312
Divide both by 12
X=26

To find the fiction you have to do 11 times 26

11•26=286

To check the answer you add 286 and 26

If it adds up to 312 the answer is correct

P(HHH)= (1/2)(1/2)(1/2) <-- each toss has 2 possibilities and heads is one 
P(HHH)=1/8

Therefore, the probability of flipping 3 heads on a fair coin is 1/8

Determine the slope of the line that contains the given points <br><br> J(-5, -2), K(5, −4)
Irina-Kira [14]

Answer:

-\frac15

Step-by-step explanation:

Hello!

We can utilize the slope formula to find the slope.

Slope Formula: S = \frac{y_2-y_1}{x_2-x_1}

Remember that a coordinate is written in the form (x,y)

<h3>Find the Slope</h3>
  • S = \frac{y_2-y_1}{x_2-x_1}
  • S = \frac{-4-(-2)}{5-(-5)}
  • S = \frac{-2}{10}
  • S = -\frac15

The slope of the line is -\frac15.
