hope this helps! :)
Step-by-step explanation:
4x=36
divide both sides of the equation by 4
4x / 4 = 36 / 4
Any expression divided by itself equals 1
x= 36 / 4
Calculate the quotient
36/4 = 9
<u>x=9</u>

Answer:
Step-by-step explanation:
The equation for the amount of money in an account after a certain amount is deposited and compounded after t years once per year is

Our A(t) = 33800, P = 4400, r = .075 and we are looking for t. Filling in:
and

Begin by dividing both sides by 4400 to get

The only way to move that t our from its current position as an exponent is to take the natural log of both sides and follow the rules for natural logs:

The power rule of natural logs says we can move that exponent down in front, giving us:

Divide both sides by ln(1.075) to get

Do this division on your calculator to get
t = 28.2 years
Answer:
<h2><u><em>
6 feet</em></u></h2>
Step-by-step explanation:
Find the height of a square pyramid that has a volume of 8 cubic feet and a base length of 2 feet
Volume v = 1/3*a²h
inverse formula
8 = 1/3 * 2² * h
8 = 4 h /3
divide both the sides by 4
<u><em>h = 6 feet</em></u>
