Question

The length of a football field is $30$ yards more than its width. How do you express the length of the field in terms of its width $w$?

Answer 1

Hint:We will start off by explaining the term “more than the other term”. Then we will be mentioning the steps to solve such types of questions. We have considered an unknown variable as $w$ to further simplify and evaluate the terms. Also, we will mention some other rules as well.

Complete step by step answer:
We will start off by mentioning the term “more than the other term”. So, the term means that if we add some value to the given variable we will get the other term.
So, here we are told that the length is $30$ more than the width and $30$ more than the width is expressed as $w + 30$
Hence, we can express the length of the field as,
$length\, = \,w + 30$
Additional Information:
Expression is a mathematical sentence which has numbers, variables, and operations and there is no equal sign. Simplify means to break down an expression to its simplest forms. Variable is a number that we don’t know, or which can change. Algebraic expressions are useful because they represent the value of an expression for all of the values a variable can take on. Sometimes in math, we describe an expression with a phrase. When we describe an expression in words that includes a variable, we are describing an algebraic expression, an expression with a variable.

Note: While converting orders do not matter for addition and multiplication. But order is important for subtraction and division. Make sure that you read the statement twice before translating it to an expression. Pay extra attention to the statements where multiplication and division is involved.
