To represent the total field goal points scored in the first two quarters, let ( x ) be the number of field goals made in the first quarter and ( y ) be the number of field goals made in the second quarter. Each field goal is worth 2 points, so the expression for total points scored in the first two quarters is ( 2x + 2y ). Simplifying this, the linear expression in simplest form is ( 2(x + y) ).
Let P be the final points, A be the awarded points, F be the number of times the skater falls. So we have P = A - 1.2*F
To write the quotient of a number and 6 as an expression, you can represent the number as a variable, such as ( x ). The expression would then be written as ( \frac{x}{6} ). This indicates that the number ( x ) is being divided by 6.
10^-1 = 0.1
The expression is 9*x.

A numerical expression is an expression that uses number. For example, if a teacher told you to write four plus six subract two , you would simply write it in number form. 4+6-2.
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
X = " a number " X + 20
To write the algebraic expression for "2 less than a number," first define the number as a variable, commonly ( x ). The phrase "2 less than" indicates subtraction, so the expression would be ( x - 2 ). Therefore, the algebraic expression is ( x - 2 ).
To write an expression that represents the sum of a number and 12, you can use a variable to represent the unknown number. For example, if you let the variable ( x ) represent the number, the expression would be ( x + 12 ). This indicates that you are adding 12 to whatever value ( x ) holds.
