Question

va rog ajutatima e urgent doar ultimele 2 exerciti H&I

Answer 1

(4 + 2 -1 × 2) × ( 4 -2 ) × h = 80
4× 2 × h = 80
8h = 80
h = 10

9+9 - 56:8 = i +9
18 - 7 = i+9
11= i + 9
i = 11 - 9
i = 2

Answer 2

(2×2+2-2:2×2)×(2×2-2:1)×h=8×8:8×10
(4+2-1×2)×(4-2)×h=64:8×10
(4+2-2)×2×h=8×10
(6-2)×2×h=80
4×2×h=80
8×h=80
h=80:8
h=10

63:7+27:3-(48+8):(11-3)=i+9
9+9-56:8=i+9
18-7=i+9
11=i+9
i+9=11
i=11-9
i=2
