4/f + 11 =29 what does f =
Delvig [45]
\frac{4}{f} + 11 = 29

First, subtract '11' from each side.
\frac{4}{f} = 29 - 11

Second, subtract '29 - 11' to get '18'.
\frac{4}{f} = 18

Third, since we are solving for f, we have to get it by itself. Multiply each side by 'f'.
4 = 18f

Fourth, once again, we need to get 'f' alone. Divide both sides by 18. 
\frac{4}{18} = f

Fifth, now that we have 'f' by itself, we can simplify the current fraction. To do so, we need to start off with listing the factors of 4 and 18 and find the greatest common factor (GCF).

Factors of 4: 1, 2, 4
Factors of 18: 1, 2, 3, 6, 9, 18

Out of the listed factors, 1 and 2 are the common factors, and since 2 is the highest number out of them, it is considered the greatest common factor. The GCF is 2.

Sixth, divide the numerator and denominator by the GCF (2).
4 \div 2 = 2  \\  18 \div 2 = 9

Seventh, we can now rewrite our fraction in simplest form and switch sides.
f =  \frac{2}{9}

Answer in fraction form: \fbox {2/9}
Answer in decimal form: \fbox {0.2222}

URGENT!! I NEED HELP ASAP NOT ROCKY
Anestetic [448]

Answer:

  • $9000

Step-by-step explanation:

<u>Given</u>

  • Monthly payment P = $300
  • Time t = 3 years = 36 months
  • Number of payments n = 36
  • Interest rate r = 12% PA = 1% per month = 0.01 times

<u>Use loan payment formula:</u>

  • P = r(PV) / (1 - (1 + r)⁻ⁿ),
  • where P- monthly payment, PV - present value (amount of the loan), r -rate of interest, n- number of payments

<u>Substitute values and solve for PV:</u>

  • 300 = (0.01*PV) / (1 - (1 + 0.01)⁻³⁶)
  • PV = 300*(1 - 1.01⁻³⁶ )/ 0.01
  • PV = 9032.25 ≈ $9000 (rounded to the nearest hundred dollars)
