Answer: There are 20 goats and 18 chikens.
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
If the number of chickens is represented by C, and the number of goats is G.
Total of Animals equation:
a)C+ G = 38
Total of legs equation (since chickens have 2 legs and goats have 4 ):
b)2C + 4 G =116
If we multiply a) by 2 and subtract a) from b).
<em>2C + 4 G =116
</em>
<em>-
</em>
<em>2C + 2 G =76
</em>
<em>_________
</em>
<em>2G = 40
</em>
G = 40/2
G= 20
Replacing the value of G on any equation:
a) C+ (20) =38
C =38-20
C=18
There are 20 goats and 18 chickens.
10 ounces + 14 ounces + 40 ounces= 64 ounces, or 4 pounds
The new cost would be 19.55.
Explanation: 1. 23 * 0.15 = 3.45
2. 23 - 3.45= 19.55
Answer: b
Step-by-step explanation:
We want to rewrite the following equation
With d as a function of the other terms. Let's start by subtracting n from both sides.
Now, let's divide both sides by 9.
And this is our final answer.
