Add 31 to both sides which will give you
9h = 130
I belive it is the second option!
By defining how exponents work, we conclude that 4^3 = 64, so the correct option is A.

How to find the cube of 4?</h3>
Let's remember how exponents work.
If we have a number a to the exponent n:
a^n
It means that we need to multiply the number a by itself n times.
Then, in this case:
4^3
Can be rewritten to.
4*4*4
Now we can solve that product:
4*4*4 = (4*4)*4 = 16*4 = 64
Then we conclude that the correct option is A
4^3 = 64

Answer:
The number is 16
Step-by-step explanation:
3/4 n- (-16) = 28
3/4 n + 16 = 28
Subtract 16 from each side
3/4 n +16-16 = 28-16
3/4 n =12
Multiply by 4/3 to isolate n
4/3 * 3/4 n = 12 * 4/3
n = 16
<span>Since we need to convert “miles per second” to “miles per hour,” we first need to find out how many seconds there are in a hour.
We know that there are 60 seconds in a minute, and if we wanted to do an hour we would have to do 60 * 60 which is 3600 seconds, therefore,
</span>1 mi/57.1 sec = (1 mi/ 57.1 sec)(3600 sec/1 hour)
= (3600/57.1) mi/hours
<span> = 63.047 mi/hours</span>
