Step-by-step explanation:
To find - 1. Label each as either an equation or an expression.
a) 5x - 3 = 12
b) 6x - 3
c) 7x + 5 = 9
2. Label each part of the equation. (numerical coefficient, variable, constant term.
What are the math questions
5x-3=12
6x-3
7x+5=9
Are they an equation or expressions?
Solution -
1.
An expression containing variables, numbers, and symbols.
An equation that has equal to sign.
a.)
5x - 3 = 12
It is an equation (because it has = sign)
b.)
6x - 3
It is an expression
c.)
7x + 5 = 9
It is an equation (because it has = sign)
2.
Variable is those whose values can be change. For example x, y, z...
Constant term whose values are fixed. For example 10, 4, 5
Numerical coefficient are the constants that placed just before the variable. For example in 4x- 4 is the variable coefficient.
a.)
5x-3=12
5 is Numerical Coefficient
12 and -3 is constant term
x is variable
b.)
6x-3
6 is Numerical Coefficient
-3 is constant term
x is variable
c.)
7x+5=9
7 is Numerical Coefficient
9 and 5 is constant term
x is variable
