A car-carrier trailer weighs 35,000 pounds when empty. The driver loads 7 cars on the trailer. The cars are identical except for
astraxan [27]

Answer:

Each car weighs 2,265 pounds

Step-by-step explanation:

Given that the car carrier weighs 35,000 pounds when empty, that is, without cars, and that loading 7 cars its weight is 50,855 pounds, the difference between both values implies the weight of the 7 cars together, which is determined through the following calculation:

50,855 - 35,000 = X

15.855 = X

Thus, the weight of the 7 cars together is 15,855 pounds. In turn, the weight of each particular car is determined from the following division:

15.855 / 7 = X

2,265 = X

Therefore, each car weighs about 2,265 pounds.

I am giving brainliest, IF WORK IS SHOWN. please help.
lord [1]

Answer:

-2/3

Step-by-step explanation:

The equation of the series:

a_n = \frac{5-(n-1)}{3} \\a_n = \frac{6-n}{3}\\

Where a_n is the nth term and n is the number of terms.

Now let's calculate the partial sum. The equation for the partial sum should be: S_n = \frac{1}{2}(a_1 +a_n)

The first term is 5/3.

The 15th term according to our previous equation is:

a_{15} = \frac{6-15}{3} \\a_{15} = -3

Put all that together we get:

S_{15} = \frac{1}{2}(\frac{5}{3}+(-3))\\S_{15} = \frac{5}{6}-\frac{3}{2}\\S_{15} = -\frac{2}{3}
