Question

РАСКРОЙТЕ СКОБКИ И УПРОСТИТЕ!ПОМОГИТЕ! -(p+3,18)+(6,08+p), 12a-17b-(13b-15a+2a), 0,3(8p-5k)-2/9(4,5p-3,6k)

Answer 1

-р-3,18+6,08+р=2.9

12а-17б-13б+15а-2а=-5а-30б

2,4р-1,5к-13,05р+10,44к=-10,65р+8,94к

 

 

 

 

Answer 2

-(p+3,18)+(6,08+p) = -p - 3,18 + 6,08 + p = 2,9

12a-17b-(13b-15a+2a) = 12a - 17b - 13b + 15a - 2a = 13a - 30b

0,3(8p-5k)-2/9(4,5p-3,6k) = 2,4p - 1,5k - (1/5p - 2/5k) = 2,4p - 1,5k - 1/5p + 2/5k = 2,6p - 0,7k
