Answer:
The digit 6 in February is worth 1/100 of its value in January.
Step-by-step explanation:
The value of a given digit in a number can be found by setting the other digits to zero.
In February, the digit 6 has a value of 00600 = 600.
In January, the digit 6 has a value of 060000 = 60,000.
The ratio of the value in February to the value in January is ...
600/60000 = 1/100
The digit 6 in February is one hundredth of the digit 6 in January.
1. 9y = -3x - 39....add 3x to both sides
3x + 9y = -39 <== standard form
2. -2x + 2y = -2. ..multiply by -1
2x - 2y = 2 <== standard form
3. -2x = 20
x = -20/2
x = -10....now sub this back into the second equation
3x - 4y = -2
3(-10) - 4y = -2
-30 - 4y = -2
-4y = -2 + 30
-4y = 28
y = -28/4
y = -7
solution is (-10,-7) <== solution
Using it's formula, it is found that the monthly payment should be of $688.49 in order to pay off the debt in 15 years.
<h3>What is the monthly payment formula?</h3>
It is given by:
In which:
- n is the number of payments.
For this problem, the parameters are given as follows:
A = 90000, r = 0.045, n = 15 x 12 = 180.
Hence:
r/12 = 0.045/12 = 0.00375.
Then we solve for A to find the monthly payment, as follows.
A = $688.49
