Tìm x thuộc N, biết:
a) (x - 50) : 45 + 240 = 300
b) 7200 : [200 + (33 600 : x) - 500] = 4
a)
(x - 50) : 45 + 240 = 300
(x - 50) : 45 = 60
x – 50 = 2700
x = 2750
b)
7200 : [200 + (33 600 : x) - 500] = 4
200 + (33 600 : x) – 500 = 1800
33 600 : x = 2100
x = 16
x + 200 = 300 + 600

a) 200 mm + 100 mm 300 mm – 100 mm 200 mm x 3 600 mm : 3
b) 300 g + 200 g 200 g × 5 500 g – 300g 1000g : 5
c) 400 ml + 300 ml 800 ml : 4 700 ml – 300 ml 200 ml x 4
a) 200 mm + 100 mm = 300 mm 300 mm – 100 mm = 200 mm |
200 mm x 3 = 600 mm 600 mm : 3 = 200 mm |
b) 300 g + 200 g = 500 g | 200g x 5 = 1 000g | 500g – 300g = 200g | 1 000g : 5 = 200g |
c)
400 ml + 300 ml = 700 ml
