Suppose there were m married couples, but that d of these 2m. people have died, Regard the d deaths as striking the 2m people at
iren2701 [21]

The function that represents surviving people are X = 2m - d

Given that there are m married couples and d of the 2m of these couples have died, the total people that remain is expressed as:

Total people remaining = Total married couple - those that died

Total married couple = 2m

Total people that died = d

Taking the difference to get the remaining people;

Total people remaining = 2m - d

Hence the function that represents surviving people are X = 2m - d

What is the answer to the equation 3(x+4.5)=36?
kozerog [31]

Answer:

x = 7.5

Step-by-step explanation:

3(x + 4.5) = 36

3x + 13.5 = 36

3x = 36 - 13.5

3x = 22.5

x =  \frac{22.5}{3}

x = 7.5
