Answer:
b = 1
Step-by-step explanation:
8 = b - 1 + 8b
<em>combine like terms</em>
8 = 9b - 1
<em>add 1 to both sides of the equation</em>
<em>8 + 1 = 9b - 1 + 1</em>
<em>8 + 1 = 9b</em>
9 = 9b
<em>divide both sides of the equation by 9</em>
9/9 = 9b/9
1 = b

Answer:
Mrs. Wong spend $545.76 on tiles.
Step-by-step explanation:
Mrs. Wong has 144 tiles that she is going to place on her square kitchen floor. If the tiles are $3.79 each, how much did Mrs. Wong spend on tile?
we are given
number of ties=144
cost of one tie=3.79 dollar
we have to find
total cost of 144 ties
for this we will multiply 144 by 3.79
multiplying 144 by 3.79 gives=144*3.79
it other words
one tile cost=$3.79
and for 144 ties cost
multiplying 144 on both sides
144 tiles cost=3.79*144=$545.76
