-1/4 + f/8 = 1/2.
The LCD is 8.  Rewrite this equation as    -8/4 + 8f/8 = 8(1/2) and then reduce the result:

-2 + f = =4

Then f = 6.

You should check this result.

If you use the addition property of equality , what number would you add to both sides of the equal sign to isolate the variable
kkurt [141]

Answer:

The answer is "\frac{26}{7}"

Step-by-step explanation:

The whole question can be found in the file attached.

\to x + \frac{5}{7} = \frac{31}{7}\\\\

Subtracting the \frac{5}{7} from both sides of the equations:

\to x +\frac{5}{7}  - \frac{5}{7}  = \frac{31}{7}  - \frac{5}{7} \\\\

                    = \frac{31-5}{7} \\\\= \frac{26}{7} \\\\

12 \frac{2}{3}

- 9 \frac{3}{4}

= \frac{38}{3} 

Then,

- 9 \frac{3}{4}

Next, our final answer:

= \frac{35}{12}

= 2 \frac{11}{12} 

Our decimal would be 2.916667

If Tanisha has ​$nbsp 100 100 to invest at 66​% per annum compounded semiannuallysemiannually​, how long will it be before she h
Oxana [17]

Answer:

time is 6.76 years

Step-by-step explanation:

given data

amount = $150

payment = $100

rate r = 6%  = 0.06

to find out

time period t

solution

we know it is compounding continuous

so we will apply here formula that is

amount = payment × e^{rt}   ..........1

put here all value we get

amount = payment × e^{rt}  

150 = 100 × e^{0.06t}  

take ln both side

ln 1.5 =  e^{0.06t}  

0.40546 = 0.06t

t = 0.40546 / 0.06

t = 6.76

so time is 6.76 years
