Note that, since I had to divide through by a negative, I had to flip the inequality signs.
Note also that you might (as I do) find the above answer to be more easily understood if written the other way around: Always remember when doing word problems, that, once you've found the value for the variable, you need to go back and re-read the problem to make sure that you're answering the actual question.
I know that solving word problems in Algebra is probably not your favorite, but there's no point in learning the skill if you don't apply it. Pay close attention to the key words given below, as this will help you to write the inequality.
Once the inequality is written, you can solve the inequality using the skills you learned in our past lessons.
The inequality "" row, to get the right-hand column's value.
The total amount of copper in the mixture will be the sum of the copper from the two alloys put into the mixture, so I'll add the expressions for the amount of copper from the alloys, and place the total between the minimum and the maximum allowable amounts of copper:" to the left-hand side?
but we must also pay attention to the direction of the inequality.
Another thing we do is multiply or divide both sides by a value (just as in Algebra - Multiplying).
