Louisa paid $12.25 for books at a yard sale she spent $2.50 on a hardcover book and the rest on 13 softcover books each of the softcover books cost the same. what was the cost of a single softcover book. write and solve an equivalent equation

Set up the equation:

12.25 = 2.50 + 13x

x represents the price of the softcover books. 

Subtract 2.50 from both sides to get:

9.75 = 13x

Then, divide both sides by 13:

0.75 = x

So, one softcover book cost $0.75
Hope this helped!! xx

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
