Explain how you would know log3100 is between 4 and 5 without the use of a calculator.

There are 15 plates and each plate is either 7 or 12 inches diameter. which systems of equations do you use to find the number of 7 inch plates, x and 12 inch plates, y

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Solve the equation by completing the square. x^2+2x=17
