The product of 7 and a number, x, increased by 1 is between 15 and 43. what is the compound inequality that represents the situation?

Let's assume that number as x

The product of 7 and a number =7x

and then increased by 1  

so, it will become

=7x+1

now, it is between 15 and 43

so, we can write as

now, we can solve for x

Since, we have to isolate x

step-1:

Subtract all the  sides by 1

step-2:

Divide all the sides by 7

so, solution is

its a wood chuck that can chuck wood

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)
