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
The more fuel efficient car is the car that has 28 miles to a gallen.She would be saving 752 dollars.
Total number of parts:
2+3=5.
Each part is:
20 cookies/ 5 parts= 4 cookies/part.
Number of chocolate cookies is:
4 cookies/part* 2 parts= 8 cookies.
Number of sugar cookies is:
4 cookies/part* 3 parts= 12 cookies.
There are 8 chocolate cookies and 12 sugar cookies~
Answer:
2(x+6)(x-3)
Step-by-step explanation:
Factor the GCF out of the trinomial on the left side of the equation.

Greatest common factor of 2, 6, 18 is 2
so GCF is 2
divide each term when we take out GCF 2
so 
now factor the trinomial
product is -18 and sum is +3
6 times -3 is -18 and 6-3=3

12) (shaded region) 12x25 =300
( un- shaded region) 6x10=60
300-60=240
240 is the answer for #12
