Hello : 
\frac{5}{a} - \frac{2}{1-a} = \frac{2}{a-1} = \frac{5}{a}+ \frac{2}{a-1} = \frac{2}{a-1}
= \frac{5(a-1)+2a}{a(a-1)} = \frac{2a}{a(a-1)} 
(a \neq 1  ,  a \neq 0)

5a-5 +2a =2a
5a =5
a=1 ( refused)
conclusion : <span>none</span>

(Plz, im desperate!)A certain bakery has found that the daily demand for bran muffins is 7700/p, where p is the price of a muffi
melisa1 [442]

Answer:

P = 70 cents per muffin

Step-by-step explanation:

It says to find the price when the supply and demand are equal, so you have to set the two equations equal to each other.

7700/p = 3p-100.

It seems to me that the best way to solve this would be to set up a quadratic equation.

If you multiply both sides by p and then subtract 7700, you get the following:

0=3p^2 -100p -7700

I wrote a program to solve this, and I got the answers p= 70 and -36.67.

Obviously, a negative number doesn’t work in this situation, so the answer is 70 cents per muffin. To check this, you can plug it back into the equation:

7700/70=3(70)-100

110=110

What is the purpose of preparing a trial balance?
AlladinOne [14]

Answer:

The purpose of a trial balance is to prove that the value of all the debit value balances equals the total of all the credit value balances. If the total of the debit column does not equal the total value of the credit column then this would show that there is an error in the nominal ledger accounts.

Softa [21]

Answer: Option C. Married and grade 2 (92.6%) is higher than Single and grade 2 (5.2%)

Solution:

Conditional relative frequency single employees in grade 2:

[(Single employees in job grade 2)/(Total employees in job grade 2)]*100%=

(222/4,239)*100%=0.052370842*100%=5.2370842% approximately 5.2%


Conditional relative frequency married employees in grade 2:

[(Married employees in job grade 2)/(Total employees in job grade 2)]*100%=

(3,927/4,239)*100%=0.926397735*100%=92.6397735% approximately 92.6%


92.6%>5.2%:

Married and grade 2 (92.6%) is higher than Single and grade 2 (5.2%)
