Last year a large trucking company delivered 4.5 x 105 tons of goods with an average value of $22,000 per ton. what was the total value of the goods delivered? write the answer in scientific notation.

Step-by-step explanation:

In order to solve this we first have to multiply the 4,5x10^5 tons of goods to normal notation:

4,5+10^5=450000

Now we multiply this by the value of each ton:

450,000*22,000=9,900,000,000

As yo can see the number is in regular notation, we just count the number of position that we need to move the decimal point from the first number and that would be 9 positions, we use that as exponent of the 10^x and we get our scientific notation:

9,9x10^9

The value of the goods delivered is 9,9x10^9 dollars.

step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
