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
Answer:
10.44
Step-by-step explanation:
First plot each of the points on to a graph at their respective positions.
Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)
You can then use the pythagorean theorem 
.
Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation. 
Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 = 
which in turn is 109 =
Then take the square root of 109 to remove the square from the c to get c = 10.44
All you need to do is divide .88 by 6.8.
.88/6.8= 0.129 (round upt to .13 cents)

To solve for these, we will use formulas and convertions as we go.
For 1:
We are looking for kg (kilograms) to g (grams). 1 g = 0.001 kg.
We have 2.5 kg. This means we must multiply 2.5 by 1,000.
2.5 x 1,000 = 2,500.
1.) is 2,500 grams.
For 2:
This problem has multiple steps, but we will successfully solve it. As of now, we have yards. There are 3 feet in a yard, and 12 inches in 1 ft. We will convert yards to feet, and then feet to inches.
500x3 = 1500, 1500 x 12 = 18,000.
2.) is 18,000 inches.
For 3:
There are 2,000 pounds in 1 ton. Using this, we can determine how many tons we have.
7,000/2,000 = 3.5
3.) is 3.5 tons.
I hope this helps!
Assuming you are trying to get price per pound.
Divide 750 by 5 which equal 150 or $1.50
