The width of a rectangle. That means we need to add 42 to the lowest grade.

At the time you decide what the variable will represent, you may think there is no need to write that down in words. We will use the approximation here. How many prescriptions did she have for tranquilizers? However many hours Karen works, we multiply that number by 6 to find out how much she earns.

Jose has a board that is 44 inches long. One side is 16 meters, and the other side is twice the first side. Answer the question in the problem The problem asks us to find a number. Re-read the problem and write an equation for the quantities given in the problem. Computers use letter variables and mathematical symbols in the Algorithms in their programs, rather than full word English sentences.

If the word problems only have numbers, then it is easy to translate them, once we have practiced doing a few word problems. The examples done in this lesson will be linear equations. Just because you found an answer to your equation does not necessarily mean you are finished with the problem.

First we need to know a formula that will relate circumference and radius since those are two pieces of information in the problem. The width of the rectangle is 10 inches.

Assign a variable for the width. We know that answer is 50, so now we have an equation Step 5: Altogether they drove 90 miles. Our Integer and Negative numbers worksheets are based on the following Singaporean Curriculum math topics: The way this is worded indicates that we find the sum first and then multiply.

We need to be careful when translating Subtraction words. The sum of a number and 9 is multiplied by -2 and the answer is Assign a variable for the lowest test grade.

There were 36 prescriptions for tranquilizers. If you need to see additional examples of linear equations worked out completely, click here. Assign a variable for the number of hours.

Here are some simple examples. The length of a rectangular map is 15 inches and the perimeter is 50 inches. Whatever the lowest grade is, we are told that the highest grade is 42 points higher than that. It will be necessary to include dollars as part of any answer we may give involving money in this problem.

Since length is 15 inches, width is w, and perimeter is 50, we get Step 5: We have one for you a bit later in this lesson. She had 84 prescriptions for the two types of drugs.

We need to just choose one and move to Step 3. The number of prescriptions for tranquilizers. We know the length is 15 inches.

We also know the perimeter is 50 inches. Assign a variable for the radius. This will help form the Algebra equation for the word problem.

We also know that the highest grade added to the lowest grade is In terms of our variable, Step 5: We are then told to multiply that by -2, so we have. We know that Jamie drove twice as far a Rhonda.

Assign a variable for the number.After having gone through the stuff given above, we hope that the students would have understood "Writing algebraic expressions from word problems worksheets".

TRANSLATING KEY WORDS AND PHRASES INTO ALGEBRAIC EXPRESSIONS To write algebraic expressions and equations, assign a variable to represent the unknown number. In the table below, the letter In translation problems, the words sum, total, difference, product and quotient imply at least two parts – use parentheses when a.

can use algebraic expressions to represent words or phrases.

Often in word problems or in other situations in math, you will be given a set of words or a phrase that you will Writing Expressions and Equations 3 times a number; t # # # 3 t Notice that in this phrase, the key word times means you should write a multiplication expression.

An algebraic equation is a bridge that connects two algebraic expressions. But, mostly such questions can be answered by converting them into algebraic equations which can be solved by algebraic methods and translate the answer back to verbal form. I created this for a mixed ability year 7 class that needed extra practise taking worded problems and translating them into algebraic expressions and equations.

Writing Equations for Word Problems The dreaded word problem is the scariest part of algebra for Right now, though, it will be be temporarily a bit frustrating to have to go through the slower step of writing Use the structure sentence from the first problem to .
