The expression is 9*x.
9x
There is no specific name. If the numerator and denominator are polynomials in the variable then the question describes an algebraic fraction. But there is no reason at all to assume that they are polynomials. There is no specific phrase that describes sin(x)/x, for example.
The phrase "4 more than twice" typically refers to a mathematical expression. If we let ( x ) represent a number, then "twice ( x )" is ( 2x ), and "4 more than twice ( x )" can be expressed as ( 2x + 4 ). This means you take double the value of ( x ) and then add 4 to it.
It is a "rational number".
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
Which phrase describes the variable expression 6.w
3n-7
The variable expression "6w" can be described as a "monomial," which is a single term consisting of a coefficient (6) and a variable (w). It represents the product of the number 6 and the variable w. In algebra, it indicates that the value of the expression changes depending on the value assigned to the variable w.
10n
To write an algebraic expression for the phrase "the product of 15 and c," you multiply the two quantities together. The expression can be written as ( 15c ). This indicates that you are taking 15 and multiplying it by the variable ( c ).
The variable expression that represents the phrase "the sum of the number of dogs and the 6 cats" is ( d + 6 ), where ( d ) is the number of dogs. This expression adds the number of dogs to the fixed number of cats, which is 6.
N + 5 With "N" being the variable.
n + 11
9t
x + 138
9x
To represent the phrase "the number of dogs" as a variable expression, you can simply use the variable ( d ). In this case, ( d ) stands for the total count of dogs being referred to. If you need to express a specific quantity or perform calculations, you can manipulate this variable accordingly, such as ( d + 2 ) for two additional dogs.
