y=605
Answer:
2 solutions
Step-by-step explanation:
Set up a system of equations. The absolute value produces two equations because one answer will be negative and the other positive.
d + 4 = -9
d + 4 = 9
So...
d = -13
d = 5
Answer:
25 goat and 15 chicken
Step-by-step explanation:
Say the number of goats is G, then the number of chickens is 40 - G as there are 40 heads and each chicken and each goat has one head.
The number of feet is 130
So 2(40 - G) + 4G = 130
So 80 - 2G + 4G = 130
2G = 50
G = 25
25 goats and 15 chickens
Use 80% *25 than you can get 20.
U believe the answer is no, I believe this because eight 9 oz. bags is 72 oubces and both of them make less than that in 10 minutes. Machine A would make 42.5 oz in 10 minutes and Machine B would make 45 oz in 10 minutes.
