All that has to be done here is to divide the number of inches by the measurement of a finger. So, divide 25 by 4 1/2 and you get approximately 5.55 fingers. The 5 repeats endlessly so bar notation can be used. If the answer is needed as a fraction, change 4 1/2 to an improper fraction to get 9/2. In this case, you're dividing 25 by 9/2, which is the same thing as multiplying 25 by 2/9, the reciprocal of 9/2. This gives you a total of 50/9 fingers, or 5 5/9 fingers as a mixed fraction.
We invested $7000 invested in two accounts, we don't know how much exactly is in each account, therefore we will assign variables to these amounts. The amount invested in the "8%" account is "x", while the other one is "y". The sum of these two numbers must be equal to $7000, therefore:
The sum of interest of each account should be equal to 580, therefore:
We need to solve the system in order to determine the values.
Now we can replace the value of "x" in the first equation to determine the value of "y".
The values are 6500 in the 8% account and 500 in the 12% account.
The given line is in point-slope form. Replace the point values with the new point and you will have your parallel line. Solve for y by adding the opposite of the constant on the left.
y - 32 = 4(x - 4) . . . . point (-3, 1) replaced with point (4, 32)
y = 4x + 16 . . . . . . . add 32 to both sides of the equation and simplify
