There are 4 semi- trailer truck park a line at the stop. After the first truck, each in the line weights 2 tons more than the tr
Anna11 [10]

Let's say the first truck weighs x tons

Then, the weight of 2nd truck = x+2 tons

The weight of 3rd truck = (x + 2) + 2 = x+4 tons

The weight of 4th truck = (x + 4) + 2 = x+6 tons

Total weight of 4 trucks:

x + (x+2) + (x+4) + (x+6) = 32

 

which can be solved easily to give x = 5

The fraction of the original mass that was lost in the second month is 1/12.

<h3>What is the fraction?</h3>

A fraction is a non-integer that is made up of numerators and denominators. An example of a fraction is 1/10.

Weight lost in the first month = 1/6 x 120 = 20kg

Weight lost in the second month = 1/10 x (120 - 20)

=  1/10 x 100 = 10kg

Fraction of the original mass that was lost in the second month : weight lost in the second month / total mass

10 kg / 120 = 1/12

DedPeter [7]

Answer:

  9 3/4 . . . . (for the numbers shown)

Step-by-step explanation:

Each number in the table is the product of the number in the left margin and the number in the top margin:

  9 = 3·3

  3/4 = 3·1/4

The total of these numbers in the table is the Area value being asked for.

  9 + 3/4 = 9 3/4

_____

If there is more to the question that isn't shown, you will need to add those partial products to the total, too. We presume you know how to add fractions and mixed numbers.
