For instance, the formula for the perimeter P of a square with sides of length s is P = 4s. You might need to solve<span> this </span>equation<span> for s, so you can plug in a perimeter and figure out the side length. This process of </span>solving<span> a formula for a given variable is called "</span>solving literal equations<span>".

The world population is estimated to be nearly 9 billion by the year 2050.
Africa- 20%
What is the estimated population of Africa in the year 2050?
9 billion x 0.2 = 1.8 billion
Answer: D
Step-by-step explanation:
<span>25 w to the sixth power over 10 w to the third power divided by 30 w squared over 5 w.
25w</span>⁶ / 10w³ ÷ 30w² / 5w
Get the reciprocal of the 2nd fraction and multiply it with the 1st fraction
25w⁶ / 10w³ * 5w / 30w² → 25w⁶ * 5w / 10w³ * 30w² = 125w⁷ / 300w⁵
*When you multiply exponents with the same base, you simply add them.
w⁶ * w = w⁶⁺¹ = w⁷
w³ * w² = w³⁺² = w⁵
Cancel out w⁵
<span>125w⁷ / 300w5 </span>= 125w² / 300
Simplify the constant:
125 / 25 = 5
300 / 25 = 12
5w² / 12 is the simplified form of the given equation.
