Answer:
40 Nickels
Step-by-step explanation:
Answer:
let the number of cows = x
let the number of chickens = y
since there are 42 heads:
x + y = 42
and since a cow has 4 legs, and a chicken has 2
4x + 2y = 144
from first equation:
x + y = 42
x = 42 - y (now, we will substitute this in the second equation)
4(42 - y) + 2y = 144
168 - 4y + 2y = 144
2y = 168 - 144
2y = 24
y = 12
now, we know the number of chickens. we will replace y with 12 in the first equation since it is more simpler
x + 12 = 42
x = 30
So, there are 30 cows and 12 chickens

Answer:
The product is the opposite of the integer
Step-by-step explanation:
I think the first answer is 41/100
Explanation:
I worked out how likely you would be to get a green marble based off of the answers, then added them together and divided by 3
2/5 = 40/100
9/16 = 50/100
3/9 = 33/100
40+50+33 =123
123/3 =41
Then for the second answer I think it’s 50% (1/2)
