Ms. Cook's class bought 2 bags of concrete and some bricks to build a border for their class garden. The bricks cost
$51. The total cost of the bricks and the concrete was $57.
Which equations can be used to find the cost, b, of 1 bag of
concrete?
o 2(51) + b = 57
o 2b + 51 = 57
O 2 + 51b = 57
ob + 51 = 57

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
