Question

detreminati pe x din:
x+250 cm2= 15 m2
2 orix+ 3 m2= 2,03 dAM2
1700 M2+ X = 29 dam2
4211000 mm2 + x= 9 m2
64000 cm2: x= 8 m2
0,5 km2 -x= 4500 dam2

Answer 1

x = 150000 cm² -250 cm² =149750 cm² = 14,975 m²
2x=203 m² -3 m²             ; 2x = 200 m²            ; x =100m²
x = 2900 m² -1700m²=1200m² = 12 dam²
x= 9m² - 4,211 m² =4,789 m²
x = 64000 cm² : 80000 cm²= 0,8 cm²
x=5000 dam² - 4500dam² =500dam²
