Answer:
3/4
Step-by-step explanation:

Effectively, divide both numerator and denominator by their greatest common factor, 12.
We have the formula:

where M is the mark down, S is the original price and N is the reduced price. Plugging the values we know:

Therefore the original price was $15.95
Answer:
$98.27
Step-by-step explanation:
70.70/100=0.707
0.707x39=27.573
70.70+27.573=98.273
Round to the nearest hundredth
$98.27
Step-by-step explanation:
7q + 3 or 7q+5 or 7q + 6
solve for q
7q + 3 =
7q + 3 -3 =-3
7q = -3
7q/7 = -3/7
q = -3/7
7q + 3 =
7q + 6 -6 =-6
7q = -6
7q/7 = -6/7
q = -6/7
Answer:
30.2 aka C
Step-by-step explanation:
The formula for the area of a circle is A = pir^2. Knowing this we can create the equation A = 3.14(3.1)^2. Following PEMDAS square 3.1 to get 9.61. Then you multiply 9.61 with 3.14 to get 30.1754. When you round to the nearest tenth you get 30.2.
