Answer:
(d + 3) would be 10
Step-by-step explanation:
<u>Step 1: Distribute</u>



<u>Step 2: Subtract 13.5 from both sides</u>


<u>Step 3: Divide both sides by 4.5</u>


<u>Step 4: Determine what (d+3) is</u>



Answer: (d + 3) would be 10
The answer is that it is positive
Answer:
n = 0
Step-by-step explanation:
Multiply parenthesis by 3 and get:
1.) 18 + 9n = 5n + 18 + 3n
Then cancel the equal terms:
9n = 5n + 3n
Collect like terms:
9n = 8n
Move variable to the left:
9n - 8n = 0
n + 0
Plugin the value of 0 into x:
3 (6 + 3 x 0) = 18
5 x 0 + 3 x 0 + 18 = 18
*If the plugged in value have the same result than the answer is correct because 18 + 18.
The initial is 21 and the rate of change is the slope so it would be 6
Answer:
Step-by-step explanation:
A = Pe^rt
A = total
P = amount you start with
r = rate
t = time
Let's calculate the rate.
99000000 = 94000000e^r*6
Divide each side by 94m
99000000/94000000 = e^6r
Take the natural log of e of both sides.
ln(99000000/94000000) = 6r
Divide each side by 6.
(ln(99000000/94000000))/6 = r
Now we can find the population in 2005.
A = 94000000e^0.00863751131 * 12
A = 104265957
The population in 2005 is 104,265,957 people.
