If u send me a link key why ess Use system of equations to solve it
A farmer who keeps goats and chickens boasted to another:
I have animals in the yard with 120 legs and only 37 heads. How many goats and how many chickens did he have?
its urgent

Step-by-step explanation:

chickens x

goats y

4x+ 2y=120           2y=120-4x/ 2        y= 60- 2x

x+y= 37                  x+y=37                x+ 60- 2x= 37

y= 60-2x

x= 23

y= 60 - 2*23            y= 14

x= 23                        x=23

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
