Ws There are 40 cows and chicken in Fred's farmyard.
One afternoon, Fred counted and found that there
were 100 legs in all. How many cows and chickens
are there? Solve this problem by writing and solving
a system of equations.

Step-by-step explanation:

step 1. let cows = c and chickens = h

step 2. c + h = 40

step 3. 4c + 2h = 100 (cows have 4 legs and chickens have 2)

step 4. solve the system. multiply step 2 by 2 and subtract from step 3

step 5. 2c = 20 or c = 10 (10 cows)

step 6. h = 30 (30 chickens)

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
