a type 1 PFD
There are four types of PFD and the Type 1 should be used by children under 10 years of age. Type 1 PFD's are intended to be used in water activities where early rescue may be expected. Children under 10 years of age must wear a USCG approved PFD when on board a boat.
Hey there! :D
3x+9= 27
Since 9 is being added, you subtract it from both sides.
3x+9 (-9)= 27(-9)
3x= 18
Divide both sides by 3, since 3 is being multiplied by x.
x=6
I hope this helps!
