À là ý bạn là

\(\dfrac{1}{2}\cdot x+\dfrac{1}{5}\cdot x+0,3\cdot x=2014\)

=>\(x\left(0,5+0,2+0,3\right)=2014\)

=>\(x\cdot1=2014\)

=>x=2014

            Giải:

Chiều cao của hình thang là: 40 x 30 : 100 = 12 (cm)

Đáy lớn của hình thang là: 12 : 20 x 100 = 60 (cm)

Diện tích hình thang là: (60 + 40) x 12 : 2  = 600 (cm²)

Đáp số:...

Chiều cao cái thùng:

8 × 5/4 = 10 (dm)

Thể tích cái thùng:

12 × 8 × 10 = 960 (dm³)

Thể tích mỗi cái hộp:

2 × 2 × 2 = 8 (dm³)

Số cái hộp cái thùng đựng được nhiều nhất là:

960 : 8 = 120 (cái)

a) 48 × 45 + 96 × 27 + 48

= 48 × 45 + 48 × 2 × 27 + 48

= 48 × 45 + 48 × 54 + 48 × 1

= 48 × (45 + 54 + 1)

= 48 × 100

= 4800

b) 48,27 : 0,125 + 48,27 : 0,25 - 48,27 : 0,5

= 48,27 × 8 + 48,27 × 4 - 48,27 × 2

= 48,27 × (8 + 4 - 2)

= 48,27 × 10

= 482,7

Thể tích bể:

5 × 1,5 × 2 = 15 (m³)

Thể tích nước trong bể: 

15 × 1/4 = 3,75 (m³)
