Forty percent of the students in a fourth grade class are 9 years old. another 0.25 are 10 years old, and the rest of the class is 11 years old. write the number of students that are 11 years old as a fraction, decimal, and percent.

Find the x coordinate of the point.

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90

Given: x - 4x > 0, then the solution set in interval notation is: (-2, 0) true o false
