Pls help, dont put random stuff pls. Write the following Arithmetic Sequence using an Explicit Formula: a1 = 8, an = an-1 – 2 an = 2 + 8(n – 1)
an = 8 – 2(n – 1)
an = 8 + 2(n – 1)
an = 2 – 8(n – 1)

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

10000

step-by-step explanation: divide by 2,

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
