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
For the 2 tabs on the table you subtract and get your answer. And for 3 and 4 you divide 90 and 55, 42 and 30. Then try to divide the other ones too :)
Answer:
50
Step-by-step explanation:
100/2
Answer:
Option B is correct.
direct variation; k = 5/2
Step-by-step explanation:
The Direct variation says:
then the equation is of the form: ......[1] where k is the constant of variation.
From the given table:
Consider x = -2 and y = -5
Substitute these in [1] to solve for k;
or
5 = 2k
Divide both sides by 2 we get;
⇒ the equation becomes:
Check:
Take x = 4 and y = 10;
10 = 10 True
Therefore, the direct variation ; best describe the function represented by the table
It would be best if you were to enclose each denominator inside parentheses. Otherwise I have to take an educated guess regarding what you meant:
1 1 x - 2
<span>1/x+1/x-3=x-2/x-3 => ----- + ------ = ----------
x x-3 x - 3
The LCD here is x(x-3).
x-3 x x(x-2)
------- + --------- = -------------
LCD LCD LCD
Then x-3+x=x^2 -3x, or 2x-3=x^2-3x or x^2 - 5x - 3 = 0
Using the quadratic formula to solve for x:
5 plus or minus sqrt(25-4(1)(-3)
x = --------------------------------------------
2
5 plus or minus sqrt( 25 + 12)
= --------------------------------------------
2
There are 2 solutions. Complete the arithmetic to find them.
Be sure to check both answers via subst. into the original equation.
