Answer:
b = [tex]\frac{ac-2c}{2a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]
Multiply through by 2ac to clear the fractions
ac = 2c + 2ab ( subtract 2c from both sides )
ac- 2c = 2ab ( divide both sides by 2a )
[tex]\frac{ac-2c}{2a}[/tex] = b

The perimeter of a rectangle is 26 inches. If the length of the rectangle is 6 inches, find the width.
Answer:
7 inches
Step-by-step explanation:
The perimeter of a rectangle = 2 x ( length + breadth)
26 = 2 x (6 + breadth)
Divide both sides of the equation by 2
26/2 = 6 + width
13 = 6 + width
Collect like terms
13 - 6 = width
width = 7 inches

What is the slope of points (2,-15) and (-3,10).
Answer:
m = 5
Step-by-step explanation:
I believe you are asking, "What is the slope of the line passing through the points (2, -15) and (-3, 10)?"
As we go from (-3, 10) to (2, -15), x (the horizontal leg of a right triangle) increases by 5 (this is the 'run'), and y (the vertical leg) increases by 25 (the 'rise'). Thus, the slope of this line is
m = rise / run = 25/5, or just 5. m = 5

A fair con is tossed 80 times in an experiment. If the coin is fair, what would be a reasonable number of times tails should appear
based on your knowledge of the theoretical probability of this event?
Answer: 40 would be a reasonable number of times tails should appear if the coin is fair. Fair means 50/50 chance.
So, divide 80 by 2. 80/2 = 40.
