The difference of two numbers is 15. the larger number is one more than three times the smaller number. find the two numbers

The two numbers are 7 and 22.

Step-by-step explanation:

To find this, we first need to set the smaller number as x. Given this, we can find the second number as 3x + 1. Using these two together, we can subtract the smaller from the larger and set equal to 15.

3x + 1 - x = 15

2x + 1 = 15

2x = 14

x = 7

Now that we have the smaller number, we can plug in to find the larger.

3x + 1

3(7) + 1

21 + 1

22

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
