Answer: m = 30
Step-by-step explanation: The equation 7m = 210 can be solved for the value of m by isolating m on one side of the equation.
To do this, we can divide both sides of the equation by 7, since dividing by 7 is the inverse operation of multiplying by 7.
So, 7m/7 = 210/7, which simplifies to m = 30.
Therefore, the value of m that makes the equation true is 30.
