Hey there!!
A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet
For heads, total = 40
Let us take the number of chickens as ' x ' and goats as ' y '
x + y = 40 ------------- ( 1 )
2x + 4y = 150 ----------- ( 2 )
Multiply the first equation with 2
2x + 2y = 80
2x + 4y = 150
Subtract the first equation from the first
2y = 70
y = 35
Number of goats = 35
substitute this in other equation
x + y = 40
x + 35 = 40
x = 5
Number of chickens are 4
Hope it helps!
Answer:
c
Step-by-step explanation:
there are 8 parts and 4 of them are red= 4/8
which simplifies to 1/2
Answer:
y = 8
Step-by-step explanation:
if you do -2 + -2 and add ten to it you get 8
Answer:
Y - intercept is 1 , slope is 3
Answer: C
Step-by-step explanation:
When there is division inside a set of parentheses, you can distribute the power to each term. When you take a power to another power, you multiply the powers.
-5 x -4 = 20
-2 x -4 = 8
So your answer is:
