15 = 5 times 3 15 = 5 + 5 + 5 15 = 7 + 7 + 1 15 = 45 - 30
2n+5 = 3n 5 = 3n-2n 5 = 1n check 2n+5 = 3n 2x5+5 = 3x5 10+5 = 15 15 = 15
multiples: 5, 10, 15 + 2 = 17 Answer: 15
How about: 3*5 = 15 as a product of its prime factors
five times the sum of a number and 8 is -15.
5Because 4*5=20and 20-5 = 15
It is 5/3 times 9 equals 15
Any whole number (integer) has factors. Factors are numbers that can be divided into another number. For example the factors of 15 are: 1, 3, 5 and 15 (1 times 15 and 3 times 5)
3x = 5x - 10 2x = 10 x = 5 Check it. 3 x 5 = 5 x 5 - 10 15 = 15 It checks.
The two numbers that solve this problem are 5 and 15. The sum of 5 and 15 is equal to 20, and 15 is indeed 3 times 5.
3 times 5 is what i got
15, obviously... reasoning: 3 times 5=15
