In this area there are a large amount of houses being built. There are a total of nine houses being built. It has taken four days to build five houses. Obviously there are more houses to be built. There is a total amount of time for two weeks for these houses to be built. How much longer (in weeks) will there be allowed to complete the construction of the houses? x+9=5(4x-2) expand both sides to remove parentheses: x+9 = 20x -10 Collect like terms on the left side of the equals sign, and constant terms on the right: x-20x = -10 -9 -19x = -19 divide both sides by the coefficient of the term in x: x = -19/-19 =1 x = the time left to complete the houses

Unformatted text preview: I will admit I am confused when it comes to writing out the problem myself on this one. I have no clue if I put a correct problem with the scenario. I do believe the problem is done correctly though. 5-x › 8 5 - 5 = 0 The answer is -x 8 - 5 = 3 The answer is 3 Now, the inequality reads:-x › 3 The last step is to divide both sides of the inequality by -1 like this: The answer is x -x ÷ -1 = x 3 ÷ -1 = -3 We are now dividing by -1, which is a number less than zero! This changes the form of your inequality. Or, in other words, your › will now become a ‹ . The solution to your inequality is: x ‹-3...
