Answer:
Step-by-step explanation:
Given that:
Keiko sold 3 less than three-fourths of his sister's sale.
To find:
Expression that represents what Keiko sold ?
[tex]1.\ \dfrac{3}{4} x - 3 \\2.\ \dfrac{3}{4} x + 3 \\ 3.\ 3 x + \dfrac{3}{4} \\4.\ 3x - \dfrac{3}{4}[/tex]
Solution:
First of all, let the sales done by Keiko's sister = [tex]x[/tex]
Now, let us consider the Keiko's sale word by word.
3 less than three-fourths of his sister's sale.
i.e. subtract 3 from the expression obtained in 1st line.
[tex]\dfrac{3}{4}x-3[/tex]
So, sales done by Keiko = [tex]\dfrac{3}{4}x-3[/tex]
So, correct answer is:
[tex]1.\ \dfrac{3}{4}x-3[/tex]
[tex]\frac{3}{4}x-3[/tex]
An algebraic expression is one that is obtained by performing a finite number of algebraic operations on symbols that represent numbers.
Any of the common arithmetic operations, such as addition, subtraction, multiplication, division, raising to a whole number power, and taking roots, is a basic algebraic operation.
Let [tex]x[/tex] denotes sale of sister of Keiko.
As Keiko sold [tex]3[/tex] less than three-fourths of his sister's sales,
Sales of Keiko [tex]=\frac{3}{4}x-3[/tex]
