2.) A 120-volt battery is connected to a circuit with 30 ohms of resistance. The current is amperes c flowing through the circuit can be found using the equation 30c = 120. How many amperes of current are there in the wire?

3.) x/7 = 2. A fraction implies division. Multiply by the denominator.

4.) 36 = w/4 A fraction implies division. Multiply both sides of the equation to find a solution.

8.) 4x = 76. An integer directly next to a variable implies multiplication. Divide to isolate the variable.
