Answer:

a) 9n + 10 years.

b) 13n + 10 years.

c) 6n - 9 years

d) 19n + 1 years.

e) 77 years.

Step-by-step explanation:

a) Prince is 6n years old. Jordan's age is (3n + 10) years more than Prince.

So, Jordan's age is (6n + 3n + 10) = 9n + 10 years.

b) The total age of Prince and Jordan will be (6n + 9n + 10) = 13n + 10 years.

c) Kimberly's age is 9 years less than Prince.

So, the age of Kimberly will be 6n - 9 years.

d) The total age of the three people will be (6n - 9 + 13n + 10) = 19n + 1 years.

e) If n = 4, then total age of three people will be 19(4) + 1 = 77 years. (Answer)

Charlie ran 5 miles in 51.5 minutes. Use the equation 5r=51.5 to find r, the average rate he ran.

5r = 51.5
r = 51.5 / 5
r = 10.3

Can someone explain the process getting from:

spin [16.1K]

$\rm 5=e^{3b}$

The unknown b is stuck in the exponent position.
We can can fix that by using logarithms.
Log is the inverse operation of the exponential.

We'll take log of each side.
Log of what base tho?

Well, the base of our exponential is e,
so we'll take log base e of each side.

$\rm log_e(5)=log_e(e^{3b})$

We'll apply one of our log rules next:
$\rm \log(x^y)=y\cdot\log(x)$

This allows us to take the exponent out of the log,

$\rm log_e(5)=(3b)log_e(e)$

Another thing to remember about logs:
When the base of the log matches the inside of the log,
then the whole thing is simply 1,
$\rm log_{10}(10)=1$
$\rm log_5(5)=1$
$\rm log_e(e)=1$

So our equation simplifies to this,

$\rm log_e(5)=(3b)\cdot1$

As a final step, divide both sides by 3,

$\rm \frac13log_e(5)=b$

k, hope that helps!

Where does this real # belong?

Eddi Din [679]

It is irrational because it is a decimal that doesn't terminate or repeat! :)
