Kyle asks his friend jane to guess his age and his grandmother’s age. kyle says his grandmother is not more than 80 years old. he says his grandmother’s age is, at most, 3 years less than 3 times his own age.

jane writes this system of inequalities to represent k, kyle’s age, and g, kyle’s grandmother’s age.

inequality 1: g > 80
inequality 2: g ≤ 3k – 3

which inequality did jane write incorrectly, and how could it be corrected?

a inequality 1 is incorrect; it should be g ≤ 80.
b inequality 1 is incorrect; it should be g ≥ 80.
c inequality 2 is incorrect; it should be g < 3k – 3.
d inequality 2 is incorrect; it should be g ≥ 3k – 3.

The answer is A on ed

step-by-step explanation:

if x = 2 you have to find x to finish the problem

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
