x + 12 + 19x + 8 = 180
x + 19x = 20x (combining like terms)
12 + 8 = 20 (combining like terms)
20x + 20 = 180
180 - 20 (subtracting 20 to both sides)
20x = 160
160 / 20 = 8 (dividing by 8 on both sides)
<em>x = 8</em>
CDA = x + 12
CDA = 8 + 12
<u>CDA = 20</u>
1/4 +1/8=3/8 ////////////////////////////////
712/34 divide it then you have your answer :)
Answer:

Step-by-step explanation:
Given
Population in 1995 = 2400
Population in 2000 = 4000
Required
Determine the linear equation
Let the years be represented with x.
In 1995, x = 1 i.e. the first year
In 2000, x = 6
Let y represents the population
When x = 1; y = 2400
When x = 6; y = 4000
First, we calculate the slope (m)




Next, we calculate the line equation as follows:





Like terms are those terms that are having the same variables, also the variables are of the same order as well. The first step to solving an equation is to rearrange the like terms.
<h3>What are Like terms?</h3>
Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
To solve an equation the first step is to rearrange the equation such that like terms are together.
Hence, the first step to solving an equation is to rearrange the like terms.
