A tub shaped like a cylinder with a radius of 20 in. and a height of 15 in. is filled to the top with water. Six spherical balls, each with a radius of 6 in., are placed in the tub and they sink. Some water overflows from the tub. This amount equals the combined volume of the spheres. Find both the exact and the approximate amount of water that remains in the tub. For the approximate volume, use 3.14 for π. Exact: __ π in3 Approximate: __ in.

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
