Carys is checking her tax bill for the last year.
AfilCa [17]

Answer:

$7,440.

Step-by-step explanation:

$0-$11,000 = no tax.

$11,000-$43,000 = 20%.

$43,000-$150,000 = 40%.

The earnings over $150,000 = 45%.  etc....

$45,600, = Revenue

Tax is 11000-43000  is = 0.20 * (32000)

= 11000-43000 = 6400

Tax  is 43000-45,600 is  = 0.40 *(2600)

=  45,600-43000 = 1040

=6400+1040 =7440

Which expressions are equivalent to 12 - 14/3t + 2/3t? Select ALL that apply. Please show how you got the answer.
geniusboy [140]

Answer:

B and F

Step-by-step explanation:

Equivalent expressions are expressions which in simplest form are equal. Simplify each expression to see each equals the simplest form of 12 - 14/3 t + 2/3 t.

12 - 14/3t + 2/3 t simplifies to 12 - 12/3t = 12 - 4t.

The options are:

a. 8t

b. 12-4t

c. -4(3 + t)  = -12 - 4t

d. 4(t - 3)  = 4t - 12

e. 12 - 16/3t

f. -4(t - 3) = -4t + 12

b and f are equivalent
