Final answer:
To find a reasonable estimate for the value of m in the equation 7m = 9158012100, divide both sides of the equation by 7 to get m ≈ 1309715871.
Step-by-step explanation:
To find a reasonable estimate for the value of m in the equation 7m = 9158012100, we can divide both sides of the equation by 7. This gives us:
m = 9158012100 / 7
Simplifying the division, we get m ≈ 1309715871. Therefore, option a) m ≈ 1309715871 is a reasonable estimate for the value of m in the equation.
