A car owner buys diesel at rs 7.50, rs 8, rs 8.50 per litre for three successive years. what approximately is the average cost p
alex41 [277]

Answer:

Average cost per litre of diesel = rs 8.00

Step-by-step explanation:

Amount spent on diesel each year = rs 4000

Price of a litre of diesel in the first year = rs 7.50

Price of a litre of diesel in the second year = rs 8.00

Price of a litre of diesel in the third year = rs 8.50

Average cost per litre of diesel = \frac{p_{1} + p_{2} + p_{3}  }{n}

where n is the number of years.

Average cost per litre of diesel  =  \frac{7.5 + 8.00 + 8.50}{3}

                                                     = \frac{24}{3}

                                                     = 8

Average cost per litre of diesel is rs 8.00

So that he buys an average of 500 (i.e \frac{4000}{8}) litres every year.

When number can each term of the equation be multiplied by to eliminate the fractions before solving 6-3/4x+1/3=1/2x+5​
PolarNik [594]

Answer:

12

Step-by-step explanation:

You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):

4=2^2\\3=3\\2=2

Therefore, we need to include a factor of 3, and two factors of 2 (2^2) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.

Our LCD is = 3*2^2=13*4=12
