Using a system of equations, it is found that:
- There are 8 chickens in the yard.
- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------
- A chicken has 1 head, as do a pig.
- There are 24 heads.
Thus:
-----------------------------------------
- A chicken has 2 feet.
- A pig has 4 feet.
- In total, there are 80 feet.
Thus:
-----------------------------------------
Number of chicken:
Since
There are 8 chickens in the yard.
-----------------------------------------
Number of pigs:
There are 16 pigs in the yard.

Answer:
Yellow Paint: 0.44736842105%
Red Paint: 0.19736842105%
Water: 0.35526315789%
Step-by-step explanation:
Yelow:
30 x 0.3 = 9
8 + 9 = 17
30 + 8 = 38
17/38 = 0.44736842105%
Red:
30 x 0.25 = 7.5
7.5/38 = 0.19736842105%
Water:
30 x 0.45 = 13.5
13.5/38 = 0.35526315789%
Solving we get
Step-by-step explanation:
We need to solve:
It can be solved using the exponent rule. If bases are same, then the exponents are added. i.e

Answer:
376 miles each day
Step-by-step explanation:
If Angie's grandma wants to drive the same distance each day, she can divide her journey in to two equal halves.
The total distance that Angie's grandma has to drive is 752 miles so each day she may need to drive,
miles
Also, it takes 12 hours to drive 752 miles, so the speed at which Angie's grandma should drive is,
At this speed if she drives 6 hours a day, she may need to drive,
miles in a day.
