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
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
It can be: x-7
18 - 3n
It can be: 7-4x as an algebraic expression
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.
y = 125 - x
If x is the unknown variable then it can be: x-16
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
