<u><em>Golden Rule: whatever you do to one side of the equation you do to the other side </em></u>

x is gonna be used as my representation of a number (x = a number)

3= 5x -2

flip the equation so the x is on the right side of the equation

move the 2 the other side of the equation

5x -2 = 3

+2 +2

5x = 5

separate the 5 from x by using division

5x/5 = 5/5

x=1

If a bank account doubles in size every 5 years, then by what percent does it grow after only 3 years? Round to the nearest tent

mr Goodwill [35]

Answer:

Step-by-step explanation:

Alright, let get started.

Suppose the initial deposit in account = x

After five years, this accounts get doubled means = 2x

Means in 5 years , the growth = $2x-x = x$

So, in 1 year, the growth will be = $\frac{x}{5}$

So, in 3 years, the growth will be = $\frac{x}{5}*3=\frac{3x}{5}$

So percent grwoth will be = $\frac{\frac{3x}{5}}{x}*100 = 60$

Hence percentage growth is 60 %. : Answer

Hope it will help :)

A 15 pound bag of ice costs $ 1.80. Give the unit rate.

Vaselesa [24]

We can use a rule of three simple, direct proportion to solve this problem.
15 pounds correspond to $1.80, then the question is to find the price of one pound, the called unit rate. We state the rule of three:
15 pound ----> $1.80
1 pound -----> x
x = (1)(1.80)/15
x = 0.12
Therefore, each pound costs $0.12 that is the unit rate in pounds
