Hey there!! 
A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet 
For heads, total = 40 
Let us take the number of chickens as ' x ' and goats as ' y ' 
x + y = 40 ------------- ( 1 ) 
2x + 4y = 150 ----------- ( 2 ) 
Multiply the first equation with 2 
2x + 2y = 80 
2x + 4y = 150 
Subtract the first equation from the first 
2y = 70 
y = 35 
Number of goats = 35 
substitute this in other equation 
x + y = 40 
x + 35 = 40 
x = 5 
Number of chickens are 4 
Hope it helps!
 
        
             
        
        
        
Answer:
-1m-6
Step-by-step explanation:
1. Multiply -3*m = -3m
2. Multiply -3* 2 = -6
3. Combine like terms : 4m + -3m = -1m
4. -1m - 6
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<u>Use properties of exponents:</u>
<u>Simplify the given expression:</u>
- 3⁴⋅x⋅(3/x²)⁻² = 
- 3⁴·x·(3x⁻²)⁻² = 
- 3⁴·x·(3⁻²)(x⁻²ˣ⁻²) =
- 3⁴⁻²·x¹⁺4 =
- 3²·x⁵ =
- 9x⁵
 
        
             
        
        
        
Answer:
1,000,000= 10^6
10 times 10 is 100 (10^2)
10,000 times 10 is 100,000 (10^5)
 
        
             
        
        
        
I believe you would just divide 134 by 8
134/8 = 16.75
That means you would earn $16.75 per hour.
