1/8+c=4/5 pl i need help

c = 27/40

Step-by-step explanation:

1/8+c=4/5

Subtract 1/8 from each side

1/8 - 1/8+c=4/5-1/8

c = 4/5 - 1/8

The common denominator is 40

4/5 *8/8 =32/40

1/8 *5/5 =5/40

c = 32/40-5/40

  =27/40

1/8 + c = 4/5

Multiply by common denominator 40=5(8).

5 + 40c =32

40c = 32-5 = 27

c = 27/40

c = 27/40

table 3 represents a direct variation function. : )

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to
