step 1
Find the <span>average growth per year of the populations of rabbits farm A
</span><span>Over the first 2 years
for t=0
</span>numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=40
average=[40-5]/2---------> 17.5
step 2
Find the average growth per year of the populations of rabbits farm B
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=30
average=[30-5]/2---------> 12.5
step 3
<span>Compare the average growth per year of the populations of rabbits on both farms
farm A=17.5
farm B=12.5
</span><span>the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.
therefore
the answer is the option C)
</span>the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.
Answer:
c = 3 / a − b + 2
Explanation:
[ Step 1: Multiply both sides by c ]
ac = bc − 2c + 3
[ Step 2: Add -bc to both sides ]
ac + −bc = bc − 2c + 3 + −bc
ac − bc = −2c + 3
[ Step 3: Add 2c to both sides ]
ac − bc + 2c = −2c + 3 + 2c
ac − bc + 2c = 3
[ Step 4: Factor out variable c ]
c(a − b + 2) = 3
[ Step 5: Divide both sides by a - b + 2 ]
c(a − b + 2) / a − b + 2 = 3 / a − b + 2
c = 3 / a − b + 2
Answer:
x=38
Step-by-step explanation:
First, know that the sum of the angles in a triangle is 180.
Then, add the angles. 2x+38+x+x-10.
Make them equal to 180.
2x+38+x+x-10=180
Simplify.
4x+28=180
Subtract 28 from 180.
4x=152
Divide 4 from 152 to make x alone.
x=38
There you go!
