A newborn boa constrictor measure 18 inches long. An adult boa constrictor measures 9 times the lenght of the newborn plus 2 inches. how long is the adult?

Newborn = 18 inches

adult boa = 9 * 18 + 2 = 164 inches

Since all the information is given, then merely put the necessary facts in order.

Had the length of the newborn been unknown, it would have been represented by x.

9x + 2 = 164

9x = 164 - 2

9x = 162

9x/9 = 162/9

x = 18

Start with 18 * 9 = 162

Next add 162 + 2 = 164

Last put 164 on the papper
