Answer:
Cougar population was 790 at the beginning
 830-790=40
 
        
             
        
        
        
5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.
        
             
        
        
        
Answer:
Step-by-step explanation:
Mp=$1200 
Let sp be x
SP=MP-discount% of MP
x=1200-15/100 * 1200
x=120000-18000/100
x=102000/100
x=1020
the amount of money person saves=MP-SP
=$1200-$1020
=$180
therefore he saves $180
 
        
             
        
        
        
Answer:
x = 6 8/9
Step-by-step explanation:
Solve:
- 2(4x - 24) + x = 14
- 8x - 48 + x = 14
- 9x - 48 = 14
- 9x = 62
- x = 62/9
- x = 6 8/9

Answer:
1120 Eagles
Step-by-step explanation:
If the population of Eagles decreases by 4% percent each year, then in 2030 (which is 15 years later), the population would decrease by (4 × 15)%
that is 60%
This indicates that the population of bald eagles in the year 2030 would be 60% less of what it was in the year 2015.
so we have,  × 2800
 × 2800
which gives us 1680
this means that the number of bald eagles in the year 2030 would be 1680 less than the number of bald eagles in the year 2015
hence 2800 - 1680
then the answer is 1120 Bald Eagles
