a= 5x+-7
Yes, the phrase "5 times a number" is a mathematical word phrase. It represents a multiplication operation, where "5" is a coefficient and "a number" is a variable that can take different values. This phrase can be translated into a mathematical expression, typically written as (5x), where (x) stands for the unspecified number.
Let's represent the number as (x). The phrase "Eight less than five times a number" can be translated to (5x - 8), and "is seven more than the number" can be translated to (x + 7). Therefore, the algebraic equation representing the given phrase is (5x - 8 = x + 7).
To express "two less than five times a number," we can use a variable, say ( x ), to represent the number. The phrase translates to the mathematical expression ( 5x - 2 ). This indicates that you first multiply the number by five and then subtract two from the result.
This would usually be written as:5n 5x 5a etc., i.e., 5, immediately followed by the desired variable.
In mathematics it could represent the combination of two functions. e.g. f = 2x + 3 g = 5x + 9 Hence fg = f(g) = 2(5x + 9) + 3 fg = 10x + 18 + 3 fg = 10x + 21
Yes, ( x5 ) is the same as ( 5x ). Both expressions represent the same quantity, which is five times the value of ( x ). The placement of the number and the variable does not affect the multiplication operation.
-5x + 30 = 20 -5x + 30 - 30 = 20 - 30 -5x = -10 -5x / -5 = -10 / -5 x = 2
let x represent the number 2x+8= 5x 2x-5x= -8 -3x= -8 -3 -3 x= 2.67
5x-5x = 0
