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 : none

Calculate the pay for the following day of a

tino4ka555 [31]

Answer:

Step-by-step explanation:

In the morning he works four hours and 15 minutes and in the afternoon he works four hours and 15 minutes for a total of eight hours and 30 minutes. 30 minutes is 1/2 of an hour so he works for a total of 8 1/2 hours. Multiply this by his hourly rate which is $15 and this gives you $127.50

15 x 8.5 = 127.5
