PLEASE HELP 1) Les has 200 cubic yards of topsoil that contains 10% rocks. A customer will buy all of less has topsoil if it contains no more than 6% rocks. So Les well as some top soil that is 4% rocks so that the mixture is 6% rocks. Les must figure out how much to add.

Part A) Write the equation that models this mixture scenario

Part B) Solve the equation from part A

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

What is x3+3x2−16x−48 divided by x−1?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
