There are 5 cookies in each bag, and there are 20 cookies in the jar. the table shows how the number of cookies, c, depends on the number of bags, b. choose the equation which represents the rule. b c 4 40 5 45 6 50 7 55 a) c = 5b + 5 b) c = 20 − 5b c) c = 5b − 20 d) c = 5b + 20

Select the correct answer from each drop-down menu. rewrite the formula to find voltage. the formula for electrical power (p, in watts) is where v is the voltage in volts and r is the resistance in ohms. for a particular brand of water heater, r is 32 ohms and p is 0.5 watts. the formula to find v is , and the voltage at which the heater operates is volts.

How to do this , and can some one explain
