Answer: 14, 15 and 16
Step-by-step explanation:
Let the numbers be a, a+1 and a+2
We are told that the three consecutive integers are such that three times the smallest is 26 more than the largest. This can be formed into an equation as:
(3 × a) = (a+2 + 26)
3a = a + 28
3a - a = 28
2a = 28
a = 28/2
a = 14
The numbers are 14, 15 and 16
Answer:
Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455
x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills
