Solve x-1/x-4=x+1/x-2 o all real except 2, 4 0 3 no solution

PSYCHO15rus [73]

Solution

Solve

$\frac{x-1}{x-4}=\frac{x+1}{x-2}$

Step 1: Evaluate and cross multiply

$\begin{gathered} \frac{x-1}{x-4}=\frac{x+1}{x-2} \\ x-1(x-2)=x+1(x-4) \\ x^2-2x-x+2=x^2-4x+x-4 \end{gathered}$

Step 2: Collect like terms

A cyclist rides her bike at a rate of 12 meters per second. What is this rate in kilometers per hour? How many kilometers will t

IgorLugansk [536]

Answer:

Part 1) The rate is $43.2\frac{km}{h}$

Part 2) $129.6\ km$

Step-by-step explanation:

Part 1)

we know that

A cyclist rides her bike at a rate of 12 meters per second

Remember that

1 hour=3,600 seconds

1 kilometer=1,000 meters

therefore

$12\frac{m}{sec} =\frac{(12/1,000)}{(1/3,600)}=\frac{12*3,600}{1,000}=43.2\frac{km}{h}$

Part 2) How many kilometers will the cyclist travel in 3 hours?

using proportion

$\frac{43.2}{1}\frac{km}{h}=\frac{x}{3}\frac{km}{h}\\ \\x=43.2*3\\ \\x=129.6\ km$
