Question

12. Află termenul necunoscut.
45:9 + 124 x 5 + a = 943
(6 x 6:4 x b) - 25:5 = 11 x 2
8 + 36: 6 x 5 x1 + 0 +8:2 + 16:8 = X+X+X+X
​

Answer 1

Răspuns:

Explicație pas cu pas:

45 : 9 + 124 × 5 + a = 943

5 + 620 + a = 943

625 + a = 943

a = 943 - 625

a = 318

_____________________

( 6 × 6 : 4 × b ) - 25 : 5 = 11 × 2

( 36 : 4 × b ) - 5 = 22

9 × b = 22 + 5

9 × b = 27

b = 27 : 9       ⇒     b = 3

________________________

8 + 36 : 6 × 5 × 1 + 0 + 8 : 2 + 16 : 8 = x + x + x + x

8 + 30 + 4 + 2 = 4 × x

44 = 4 × x

x = 44 : 4

x = 11
