Answer:
Step-by-step explanation:
x - 30 = 14 - 3x
4x = 44
x = 11
Let's call the unknown number x
Now let's decrease it by 30, that is x-30
Now let's write out "14 decreased by three times the number", that is 14 - 3x
The problem says these are the same, that is x - 30 = 14 - 3x
We now want to isolate, or solve for, x
Move the x to one side of the equation by adding 3x to both sides
3x + x -30 = 14 - 3x + 3x
4x -30 = 14
Now move the 30 to the right hand side by adding 30 to both sides
4x - 30 + 30 = 14 + 30
4x = 44
Now all we have to do to get x is divide both sides by 4
4x/4 = 44/4
x = 11
Answer:
We will choose option D.
Step-by-step explanation:
Milton took out a loan for $2400 at 7% interest compounded annually.
So, after one year his loan will grow up to
dollars.
Therefore, the interest added to the principal is $(2568 - 2400) = $168
But Milton makes yearly payment of $140 which is less than the interest i.e. $168 which is added to his loan in the first year.
Therefore, he can not ever pay off the loan.
So, we will choose option D. (Answer)
The sum will be:
sigma(i = 1 to infinity, 30*(2/5)^i)
->

Which is equal to 30/(3/5) = 50
