Answer:
The total number of people who became members of the site that month is 360....
Step-by-step explanation:
Let x represents the total number of people who became members of the site that month.
We have the equation:
x = 0.8x+72
Combine the like terms:
x-0.8x= 72
0.2x =72
Now divide both sides by 0.2
0.2x/0.2 = 72/0.2
x= 360 people
This shows that the total number of people who became members of the site that month is 360....
Answer:
360 people became members of the site that month
Step-by-step explanation:
Solve the following equation for x

To solve for x we need to get 'x' alone

Subtract 0.8x on both sides


Divide both sides by 0.2

Step-by-step explanation:
Cut 5/12 of his lenght
remain 7/12 of his lenght
7/12*L - 6/7 *7/12*L=2 1/2 m
7/12*L(1-6/7)=7/12*L(7/7-6/7)=7/12*L*1/7=L/12 =2 1/2
⇒L=2 1/2 m *12=5/2*12=30 m
Original length was 30 m
