You will be given a problem involving the mixing of two beakers of acid.
After typing in a step, hit the "Enter" key. For the last column
in the table and in the equation, do not multiply the expression out
unless you are multiplying by 0 or
1. For example, write
expressions as .09(7-x), but if the
expression is 1(7-x) or
0(7-x) write it as 7-x or
0 respectively. This activity will ask
you to complete 12 mixing problems. It should get easier as you
become more experienced. In order to succeed with this activity,
it is expected that you already know how to solve linear equations.
