What value of a is a solution to this equation? 10a = 70 Choices: (A)a = 5 (B)a = 7

Identify Operation: Identify the operation needed to solve for a. The equation is 10a = 70, which means we need to isolate the variable a. To do this, we will divide both sides of the equation by 10, the coefficient of a.Divide by 10: Divide both sides of the equation by 10. Performing the division, we get a = 70 / 10.Calculate Value: Calculate the value of a. Now, we calculate the result of 70 divided by 10, which is 7. So, a = 7.Check Solution: Check the solution. We substitute a = 7 back into the original equation to verify if it is correct. 10a = 10 * 7 = 70, which matches the original equation.
