Question

rozwiąż równania : 3a+1 3/4=2 1/5, 1 2/3 -5c=1 1/4.1/2p:1 3/4=8 bardzo proszę

Answer 1

3a +1i3/4 = 2i1/5

3a + 7/4 = 11/5   /*20

60a + 35 = 44

60a = 44 - 35

60a = 9 /:60

a = 3/20

 

 

1i2/3 -5c = 1i1/4

- 5c = 1 i1/4- 1i2/3

-5c= 1 i3/12 - 1i8/12

-5c = -5/12 :(-5)

   c = 5/12 * 1/5

   c = 1/12 * 1/1

    c = 1/12 

 

 

1/2p : 1i3/4 = 8

1/2p : 7/4 = 8

1/2p * 4/7 =8

4/14p = 8  /:4/14

p = 8 * 14/4

p = 2 *14/1

p = 28
