3/5n - 4/5 = 1/5n....multiply everything by 5 to get rid of the fractions
3n - 4 = n
-4 = n - 3n
-4 = -2n
-4/-2 = n
2 = n <==

\frac{3}{5}n- \frac{4}{5}  = \frac{1}{5}n
Putting like terms together;
\frac{3}{5} n- \frac{1}{5}n= \frac{4}{5}
\frac{2}{5} n= \frac{4}{5}
n=\frac{4}{5} * \frac{5}{2}
n=2

Compound interest <br> Plz help!!!
liraira [26]

Answer:

a) A(t) = 17500(1.0053)^{12t}

b) The balance after 8 years will be of $29,069.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

a)

Loan of $17,500 means that P = 17500

6.4% interest rate means that r = 0.064

Compounded monthly means that n = 12. So

A(t) = P(1 + \frac{r}{n})^{nt}

A(t) = 17500(1 + \frac{0.064}{12})^{12t}

A(t) = 17500(1.0053)^{12t}

b)

This is A(8). Then

A(8) = 17500(1.0053)^{12*8} = 29069

The balance after 8 years will be of $29,069.

Help me Solve 1/6 ÷ 2/6 please
pochemuha
\frac{1}{6} ÷ \frac{2}{6}

First, apply this following rule: a ÷ \frac{b}{x} = a × \frac{c}{b}
\frac{1}{6} × \frac{6}{2}
Second, apply this following rule: \frac{a}{b} × \frac{c}{d} =  \frac{ac}{bd}
\frac{1x6}{6x2}
Third, multiply 1 × 6 to get 6 and 6 × 2 to get 12.
\frac{6}{12}
Fourth, find the GCF of 6 and 12. 
Factors of 6: 1, 2, 3, 6
Factors of 12: 1, 2, 3, 4, 6, 12
The GCF is 6.
Fifth, divide the numerator by the GCF.
6 ÷ 6 = 1
Sixth, divide the denominator by the GCF.
12 ÷ 6 = 2
Seventh, collect the new numerator and new denominator.
\frac{1}{2}

Answer as fraction: \frac{1}{2}
Answer as decimal: 0.5

Please help and explain <br><br> question 12
il63 [147K]

The sunflower is 2.387 meters tall.

The question is asking: which rounding will result in the greatest value?

To see, we need to round 2.387 to meter, tenth meter, and hundredth meter.

Meter - 2 meters

Tenth meter - 2.4 meters

Hundredth meter - 2.39 meters

As you see, rounding to the tenth meter gives the greatest value of 2.4. Therefore, Bahir should use a decimal rounded to the tenth meter.
