Answer:

86 books

Step-by-step explanation:

A stack of books is 43 inches tall.

Each book is \frac{1}{2} inch thick.

To find the number of books in tha stack, divide the height of the stack by the height of the book:

43:\dfrac{1}{2}

The division by the fraction \frac{1}{2} is equivalent to the multiplication by the fraction \frac{2}{1}, so

43:\dfrac{1}{2}=43\cdot \dfrac{2}{1}=43\cdot 2=86

What is the solution of the system?
Kryger [21]
Greetings!

Solve the System, using Elimination:
\left \{ {{4x+2y=18} \atop {2x+3y=15}} \right.

Multiply Equation #2 by 2:
\left \{ {{4x+2y=18} \atop {2(2x+3y)=2(15)}} \right.

\left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.

Eliminate variable x:
-\frac{ \left \{ {{4x+2y=18} \atop {4x+6y=30}} \right.}{0x-4y=-12}

4y=-12

Divide both sides by 4:
\frac{4y}{4}= \frac{12}{4}

y=3

Input this value into one of the Equations: 
4x+2y=18

4x+2(3)=18

Simplify:
4x+6=18

(4x+6)+(-6)=(18)+(-6)

4x=12

Divide both sides by 4.
\frac{4x}{4}= \frac{12}{4}

x=3

The Solution to this System (The Point of Intersection):
\boxed{(3,3)}

I hope this helped!
