Let the number be x and if 9+2x = 15 then x equals 3
five times the sum of a number and 8 is -15.
It is: 15 times 15 = 225
The answer is 27. 10+15=25. 25+2=27.
2*(n+15) = 6n
The sum of 45 and 15 equals 60. 15 x 3 equals 45.
Let the number be x and if 9+2x = 15 then x equals 3
five times the sum of a number and 8 is -15.
No because two plus 15 equals 17
15 and -4
The common number is 3. 3 times 3 equals 9 3 times 5 equals 15
How about: 3*5 = 15 as a product of its prime factors
It is: 15 times 15 = 225
The answer is 27. 10+15=25. 25+2=27.
2*(n+15) = 6n
It is 5/3 times 9 equals 15
The cubed root of 15 is irrational; it is approx 2.466
