Bag A contains 7x counters. Bag B contains 2x counters.
Five counters are taken from bag A and put in bag B.
Write an expression, in terms of x, for the number of counters now in bag B.

Consider this expression and the steps to evaluate it. 4^5(−2)^9/4^8(−2)^3 1. apply the quotient of powers:      (−2)^a/4^b 2. evaluate powers:           c/d select the value of each variable. a = _ b = _ c = _ d = _
