One cubic foot of sand weighs 100 pounds. a square sandbox with 5-foot sides has half of a foot of sand in it. how many pounds of sand is the sandbox holding?

Which point-slope form equation represents a line that passes through (3,-2) with a slope of -4/5

Use a transformation to solve the equation. w/4 = 8 can you also leave a detailed explanation on how this equation = 32

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.
