Let the unknown number be x: 9x-15 = 39 9x = 39+15 9x = 54 Divide both sides by 9 to find the value of x: x = 6
Product means multiply in maths. 12*15=180
product
If the number is n, and the product is of the numbers p and q, the expression is p*q + (n + 15) : the parentheses are not necessary.
The number are coprime so their LCM is their product ie 15*23 = 345
4x - 15 = 5x - 10 5x = 4x - 5 x = -5
Let the unknown number be x: 9x-15 = 39 9x = 39+15 9x = 54 Divide both sides by 9 to find the value of x: x = 6
Answer
the product of 15 and a number by its self four times.
Product means multiply in maths. 12*15=180
product
How about: 3*5 = 15 as a product of its prime factors
If the number is n, and the product is of the numbers p and q, the expression is p*q + (n + 15) : the parentheses are not necessary.
* n=15
It is 4n - 15.
It is 15 + 1x.
The number are coprime so their LCM is their product ie 15*23 = 345
