Mrs. Brown has 11 more boys than girls in her class and has a total of 28 students. Which of the following systems of equations could be used to solve this problem? A. B = G – 11 and B + G = 28 B. G = B + 11 and B + G = 28 C. B + 11 = G and B + G = 28 D. B = G + 11 and B + G = 28

How can you decide witch operations to use to slice a two step equation

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Which of the following best describes the figure?
