Answer 1

Răspuns:

Explicație pas cu pas:

(69 - a ) : 5 = 7

69 - a = 7 × 5

69 - a = 35

a = 69 - 35 = 34

9 × ( 31 - a ) = 72

31 - a = 72 : 9

31 - a = 8

a = 31 - 8 = 23

(6 × a ) : 9 = 4

6 × a = 4 × 9

6 × a = 36

a = 36 : 6 = 6

( a + 12 ) : 7 = 7

a + 12 = 7 × 7

a + 12 = 49

a = 49 - 12 = 37

(5 + a ) : 8 = 4

5 + a = 4 × 8

5 + a = 32

a = 32 - 5 = 27

( a : 6 ) : 4 = 2

a : 6 = 2 × 4

a : 6 = 8

a = 8 × 6 = 48

Ghiocel = 15

Floarea soarelui = ( 15 + 5 ) : 5 = 20 : 5 = 4

Viorea = 8 × 4 = 32

Laleaua = 32 - 2 = 30

Margareta = 30 + 30 = 60
