The lowest multiple of a number is the number itself. As:- number x 1 = the number itself
x = x/4 + 18 4x = x + 72 3x = 72 x = 24
x+>44
Let the number be x:- 4x+40 = 100-x => 5x = 60 => x = 12 So the number is 12
The product of the prime factors of a number is the number itself. 2 x 2 x 2 x 7 = 56
Answer:We need to find a number which increased by 3.5 of itself equals 621.Let that number be x.x increased by 3.5 of itself equals 621 implies x+ 3.5x = 621.x(1+3.5) = 621x(4.5) = 621x = 621/4.5x = 138Therefore the required number is 138.Source: www.icoachmath.com
let X = number X + 1/2 X = 21 1.5 X = 21 X = 14
A number h increased by i.e. added to itself = h + h =2h
Call the number we seek x, now we have .1x+x=352 or x(1.1)=352 so x=352/1.1
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.
3x+30let x = "a number"(x+10) = "a number increased by 10"3(x+10) = "3 times a number increased by 10"Expand: 3x+30
Let x = the numbernumber increased by 10 = x + 10
1.25x = 120 ∴5x/4 = 120 ∴5x = 480 ∴x = 96
A certain number increased by 4
Let x = the number x^2 + x = x x^2 = 0 x = 0
x + 4
The expression is: 8+x
