The first step for solving this expression is to write all numerators above the least common denominator. For this problem,, our least common denominator will be (x - 3) × (x - 4).
Now we will distribute 2x through the first set of parenthesis.
Distribute -4x through the second set of parenthesis.
Multiply the two parentheses in the denominator of the fraction together.
Collect the like terms with a variable of
x²
on the numerator (top) of the fraction.
Collect the terms on the numerator of the fraction with a variable of
x.
Lastly,, collect the terms with an
x variable on the denominator (bottom) of the fraction to get your final answer.

Walk = x + 6
Bike = x
Driven = x
x + x + x + 6 = 24
combine like terms
3x + 6 = 24
subtract 6 from both sides
3x = 18
divide both sides by 3 to isolate x
x = 6
Walk = x + 6 = 6 + 6 = 12
12 students walk to school.
Rounded to the nearest whole number, it would be 1. I'm not really sure that's what you're looking for though. The actual value of 2/9 is .222~, so answer accordingly
Your task is to convert 12m/s into km/min
to get kilometers from meters we need to divide by 1000 and to get minutes from seconds we need to multiply 12 by 60. The reason why we are multiplying is because minutes are bellow / sign, so dividing divisor is equivalent to multiplying entire number.
That means that the answer is converting seconds to minutes and meters to kilometers
