Answer:
ln [(x + 2)^3 ]/(x-1)
Step-by-step explanation:
3ln(x+2) - ln(x - 1) = ln (x + 2)^3 - ln (x-1)
ln (x + 2)^3 - ln (x-1) = ln [(x + 2)^3 ]/(x-1)
The class is made up of male and female students.
"A drama class has a total of 26 students"
f + m = 26
"The number of females is 16 less than the number of males"
f = m - 16
Substitute the second equation into the first.
m - 16 + m = 26
- combine like terms -
2m - 16 = 26
- add 16 to both sides -
2m = 42
- divide by 2 -
m = 21
Now substitute that answer into either equation
f + 21 = 26
- subtract both sides by 21 -
f = 5

Step-by-step explanation:
Answer:
Number of brownies = 30
Number of cookies = 15
Step-by-step explanation:
Given:
Cost of each brownie = $2
Cost of each cookie = $1.5
Total number of treats = 45
Total amount = $82.50
Find:
Number of cookies and brownie
Computation:
Assume;
Number of brownies = b
Number of cookies = c
So,
b + c = 45........eq1
2b + 1.5c = 82.50...........eq2
Eq1 x 2
2b + 2c = 90 ..................eq3
Eq 3 - Eq 1
0.5c = 7.5
c = 7.5 / 0.5
Number of cookies = 15
Number of brownies = 45 - Number of cookies
Number of brownies = 45 - 15
Number of brownies = 30
So 15% is out of 100%, and the cab company has sent 30 cabs out of x?(x is the total number of cabs).

So, by setting up that data we already know, we can make this equation to figure out how many cabs total the company actually has:
<span>15x = 100 * 30
</span>
We do the multiplication on the right side
15x = 3000
And divide to isolate the "X" variable
x = 200
So, the cab company has 200 cabs total, and they sent out 30 of them.
