Let x be the number of the chickens

 45 -x is the number of the rabbits

We have: 2x + (45-x)4 = 140

 And then, we solve for x

2x + 180 - 4x = 140

180 - 2x = 140

2x= 40

x= 20

Therefore, the number of rabbits: 45 - 20 = 25

Rabbits: 25

Chickens: 20

26.108-26.12/32-28+24-20+16-12+8-4=2496/16

\(\frac{2496}{16}\)

gà cos 2 chân

thỏ có 4 chân 

giả sử 100 con đó đều là thỏ thì số chân là:

4x100=400

số chân thừa ra là:

400-236=164

số con gà là:

164/94-2=82

82 con gà

peter có tổng cộng 100 con gà và thỏ trong trang trại của mình. Nếu tổng số các con vật có 260 cái chân thì trang trại đó có bao nhiêu con gà?

Chúc bạn học giỏi

Cảm ơn bạn nhiều 

\(\frac{48x700-24x45x20}{45-40+35-30+25-20+15-10}\)

\(=\frac{24x2x700-24x45x20}{5+5+5+5}\)

\(=\frac{24x1400-24x900}{20}\)

\(=\frac{24x\left(1400-900\right)}{20}\)

\(=\frac{24x500}{20}\)

\(=\frac{12000}{20}\)

\(=600\)

\(\frac{27x45+27x55}{2+4+6+...+16+18}\)

\(=\frac{27x\left(45+55\right)}{2+4+6+...+16+18}\)

\(=\frac{27x100}{2+4+6+...+16+18}\)

\(=\frac{2700}{\left(2+18\right)x9:2}\)

\(=\frac{2700}{90}\)

\(=30\)

\(=\frac{26x96}{16}\)

k nha

nhóm cứ hai số liên tiếp lại vs nhâu sẽ đk quy luật tổng của toàn số -2

A=2-4+6-8+10-12+14-16+18-20+22-24+26-28+30-32

A= (-2)+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)

A= -16

-16

nha!!!!!!!
