mrs. cook wants you to send a package to her friend and in spain. it costs 3$ for the packaging and then $0.20 for each ounce if she paid $15.60 how heavy was the package? be sure to define your variable and show your equation

assuming you want the answer in ounces still, its 63 ounces

Step-by-step explanation:

total = $3 + 0.20x

15.60 = 3 + 0.20x

12.60 = 0.20x

63 = x

x/3-10=8

x/3=18

x=48

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
