a dog runs 54km in just 3days ,it runs 2km more each day . how many kilometers does it run for the first 2 days?

Lesechka [4]

Let x be the distance it runs on the first day, then:-

x + x + 2 + x + 4 = 54

3x + 6 = 54

3x = 54 - 6 = 48

x = 48/3 = 16 km

So for the first 2 days it runs 16 + 18 = 34 km. Answer

there are 13 animals in a barn. some are ducks and some are pigs. there are 40 legs in all. how many of each animal are there?

konstantin123 [22]

Let X be chickens
Let Y be pigs,
then x+y=13
the animals have 2x+4y legs,
so 2x+4y=40
The system of the equations
[X+y=13
[2x+4y=40
Divide the second equation by 2
[x+y=13
[x+2y=20
subtract the first equation from the second one
y=20-13
y-7 pigs
substitute y=7 into the first equation
x+7=13
x=13-7
x=6 chickens
