Write an expression for each of the following:

a) The sum of 145 and [tex]$x$[/tex].

b) 145 decreased by the sum of 56 and [tex]$x$[/tex].

c) [tex]$y$[/tex] fewer than 145.

d) The quotient of 978 and 120.

Answer :

Sure! Let's break down each part of the question and create expressions based on the descriptions provided:

a) The sum of
This prompts us to think of adding two or more numbers. However, the question does not specify which numbers to add. A general expression would be something like:
[tex]\[ \text{Sum example: } a + b \][/tex]

b) 145 decreased 56 and [tex]\( x \)[/tex] by [tex]\( x \)[/tex]
Here, you start with 145 and decrease it by 56 first, and then also decrease it by [tex]\( x \)[/tex]. The expression is:
[tex]\[ 145 - 56 - x \][/tex]

c) [tex]\( y \)[/tex] fewer than
This is about subtraction. To say "fewer than," you'd be subtracting from [tex]\( y \)[/tex]. However, the question does not specify how much fewer than. A hypothetical expression could be:
[tex]\[ y - n \][/tex]
where [tex]\( n \)[/tex] is some number specified later on.

d) The quotient of 978 [tex]\( y \)[/tex] and 120
The word "quotient" refers to division. Here, you'd multiply 978 by [tex]\( y \)[/tex] first, and then divide the result by 120. It looks like this:
[tex]\[ \frac{978 \times y}{120} \][/tex]

These are expressions based on the descriptions given in the question. Remember to replace any placeholder values like [tex]\( a \)[/tex], [tex]\( b \)[/tex], or [tex]\( n \)[/tex] with actual values if they are provided later on.
