b) Destiny can walk back 1 mile is 16 minutes.
Step-by-step explanation:
The running rate of Destiny is

So, she runs 1 mile in
= 6 minutes
Hence, Destiny can run 1 mile is 6 minutes.
The walking rate of Destiny is

So, she walks 1 mile in
= 16 minutes
Hence, Destiny can walk back 1 mile is 16 minutes.
There were 360 guests and 216 staffs at the gala
7^(7n + 7) = 2401
apply log on both sides to solve the equation
log 7^(7n + 7) = log 2401
the power is brought forward
(7n + 7) log 7 = log 2401
7n +7 = log 2401 / log 7
7n + 7 = 4
7n = -3
n = -3/7

Those are vertical angles and vertical angles are always congruent, meaning they're equal. To find x, you must set 6x+5=83 and solve for x.
