Armin is trying to decide whether to buy a season pass to his college basketball team's 20 home games this
season. The cost of an individual ticket is $14, and the
cost of a season pass is $175. The season pass will
admit Armin to any home basketball game at no
additional cost. What is the minimum number of home
basketball games Armin must attend this season in
order for the cost of a season pass to be less than the
total cost of buying an individual ticket for each game
he attends?

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

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
