How do I know where to place an adjective in French?
French adjectives placement can be tricky because it varies depending on what the adjective is describing. There is an acronym for remembering whether an adjective goes before or after the noun it is describing: BAGS. BAGS stands for beauty, age, goodness, and size. If an adjective describes a "BAGS" quality, it goes before the noun. In all other cases, it follows the noun (unlike English). For example, jeune (young), which describes age, is a BAGS adj and would precede the noun (Le jeune homme). On the other hand, intéressant (interesting) is not a BAGS adj and would follow the noun (L'homme intéressant). If you wanted to say the young, interesting man you would say Le jeune homme intéressant.
A student got a test score of 68%. Given that there were 25 questions on the test and each was equally weighted, how many questions did that student incorrectly answer?
There are many ways that percentages can be dealt with. It is important to remember that percentages are all simply fractions over 100, and can also be represented as decimals. In our question, 68% is the same as 68/100 which is the same as .68 (if this is confusing, recognize that 68 = 68.0, then move the decimal two places to the left to represent the two zeros of 100). To figure out how many questions the student got correct, you must simply multiply .68 by the total number of questions on the test. .68 * 25 = 17. Further, we want to know how many questions the student got wrong. If there were 25 questions, and 17 were answered correctly, that leaves (25 - 17 =) 8 incorrect answers.
Solve for x 3x + 5 = 26
In order to solve for x you need to get the variable by itself (removing the 3 and 5). To do this, you must first add or subtract any constants. Since we are moving to the other side of the equation, whatever action is taking place in the original equation, the opposite must be done. For example, if the original equation contains subtraction, you will use addition. If it uses division, you will use multiplication, and so forth. The first action would be to move the 5 to the side of the 26. Since it is being added to 3x, it will need to be subtracted from 26. The idea is that whatever you do on one side of the equation, you must do to the other 3x + 5 - 5 = 26 - 5 or 3x = 21. Now we will repeat this process with 3. Since it is multiplied by x, it needs to be divided by 21. (3x)/3 = 21/3 or x = 7.
