sam solved the following problem: repost -4x + 5 > 29 -4x + 5 - 5 > 29 - 5 -4x > -24 -4x/-4 > -24/-4 x > 6 what were his two mistakes?

First mistake:

-4x > -24

Second mistake:

-4x/-4 > -24/-4

Step-by-step explanation:

We are given work as

Step-1:

Subtract both sides by 5

Step-2:

Divide both sides by -4

whenever we divide by negative sign

it's inequality gets interchanged

So, we can see that

First mistake is subtracting 5

29-5=24 ...while we have -24 there

Second mistake is to change inequality when divide by negative sign

First mistake:

-4x > -24

Second mistake:

-4x/-4 > -24/-4

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
