Answer:

For the sum of the digits of Michelle’s father to drop to 1/3 of its’ former value, the second digit must go from 9 to 0, in one year.

Thus, if he is 39 this year, the sum of the digits of his age will be 12. Next year, when the sum of the digits would be 4+0, or 4, then the digits of his age would be 1/3rd of their former value.

Therefore, he is 39, and will be 40 next year

lianna [129]

Answer:

  $1516.69 per month less

Step-by-step explanation:

The formula for the monthly payment A on a loan of principal P, annual rate r, for t years is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 18.5% loan, the monthly payment is ...

  A = 150000(.185/12)/(1 -(1 +.185/12)^(-12·30)) ≈ 2321.92

For the 5% loan, the monthly payment is ...

  A = 150000(.05/12)/(1 -(1 +.05/12)^-360) ≈ 805.23

The mortgage at 5% would be $1516.69 less per month.

Z divided by 6 + 15 = 24
yanalaym [24]

Answer:

z/6+15=24

We move all terms to the left:

z/6+15-(24)=0

We add all the numbers together, and all the variables

z/6-9=0

We multiply all the terms by the denominator

z-9*6=0

We add all the numbers together, and all the variables

z-54=0

We move all terms containing z to the left, all other terms to the right

z=54

Step-by-step explanation: hope it helps
