Question

Am nevoie urgent e ceva simplu!!
Dau coroAna!!

Answer 1

6a=30 ⇒ a=5

2c+ 2*5 = 2c+10=20

2c=20-10

2c=10

c=5

4i+5=13

4i=8

i=2

5+   5x2 = 5+10 = 15.

Answer 2

30 : 3 = 10 → valoarea unei perechi de adidasi

( 20 - 10 ) : 2 = 10 : 2 = 5 → valoarea unui robotel

( 13 - 5 ) : 2 = 8 : 2 = 4 → valoarea a doua cornete cu seminte

( 10 : 2 ) + 5 × ( 4 : 2 ) = 5 + 5 × 2 = 5 + 10 = 15
