15 - 2x
18 - 3n
y = 125 - x
The algebraic expression for "4 decreased by the quotient of a number and 7" can be represented as 4 - (x/7), where x is the variable representing the number. The expression first calculates the quotient of the number and 7 by dividing x by 7, and then subtracts that quotient from 4. This expression captures the mathematical operation described in the question.
p+0.4-(p+0.4)5 i think
Oh, dude, it's like super simple. The algebraic expression for six decreased by a number is just 6 - x. You're literally just taking six and subtracting some mystery number, like a math magician or something. So, yeah, that's it.
The algebraic expression for a number decreased by 8 can be represented as ( x - 8 ), where ( x ) is the variable representing the unknown number. This expression indicates that 8 is subtracted from the value of ( x ).
It can be: x-7
It can be: 7-4x as an algebraic expression
18 - 3n
the + of a number and 10 k decreased by 4 = k-4
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
If x is the unknown variable then it can be: x-16
y = 125 - x
n (number) minus four ----->n-4
Let x be the number and so it is: 3x-18
n = number 2(n + 15) ======
(x - 25)*4
