Examine tamika’s work below. what is tamika’s error? a.) she added the exponents. b.) she simplified the coefficients incorrectly. c.) she divided the exponents. d.) she moved bases with positive exponents.

(A)

Step-by-step explanation:

Tamika's work is wrong as:

The given equation is:

She added the components, while the components must be subtracted in this equation, thus the equation becomes

=

=

=

which is the required simplified form.

Thus, the option A is correct.

h

step-by-step explanation:

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
