Nya wants to buy a sweater that had an original price of $55. The sweater is now discounted 20% and the sales tax rate is 5.5%.
suter [353]

Answer:

$46.42

Step-by-step explanation:

a=price after discount (without sales tax)

a/55=20/100

100a=55·20

100a/100=1,100/100  (the 1,100 is from the 55·20)

You get 11 and then you have to subtract 11 from 55.

55-11=44, so a=44

Then you multiply 44·0.055         (you get 0.055 because you have to make 5.5% a decimal.  You get 2.42.

You add 2.42 and 44 and you get $46.42

Factor the GCF out of the trinomial on the left side of the equation. (2 points: 1 for the GCF, 1 for the trinomial)2x^2 + 6x -
iren2701 [21]

Answer:

2(x+6)(x-3)

Step-by-step explanation:

Factor the GCF out of the trinomial on the left side of the equation.

2x^2 + 6x - 36 =2(x^2 + 3x - 18)

Greatest common factor of 2, 6, 18 is 2

so GCF is 2

divide each term when we take out GCF 2

so 2(x^2 + 3x - 18)

now factor the trinomial

product is -18 and sum is +3

6 times -3 is -18  and 6-3=3

2(x^2+3x-18)\\2(x+6)(x-3)
