Let X be birds = ?
Y be beasts = ?
heads = 60
feet = 200
feet of birds = 2
feet of beast = 4
From data we come to know that
total animals = X+Y=60____1
total feet = 200 = 2X + 4Y_____2
from equation 1 X= 60-Y
put this value of X in equation 2
2(60-Y) + 4Y = 200
120 - 2Y + 4Y = 200
2Y= 200 - 120
2Y = 80
Y = 40
Now from value of Y we can calculate X
X + Y =60
X + 40 = 60
Or X = 20
The number of beasts is equal to 40 where as number of birds is equal to 20.
Answer:
6300
Step-by-step explanation:
Answer:
f(x+5)=3x+16
Step-by-step explanation:
lets name " x+5" T
so f(T)=3T+1
now use "x+5" replace T
now its f(x+5)=3(x+5)+1=3x+15+1=3x+16
7 units to the left of the 3.
To the right represents addituon, but since you are subtracting, it would be 7 units to the left of 3.
