Set this up as a ratio putting inches on top and feet on bottom. Then your first ratio would be 1/25 since 1 inch is the same as 25 feet. In between them goes an equals sign and the the other ratio has an x on top (because inches is what we are looking for) and the 1500 on the bottom. Cross multiply to solve for x:
1(1500) = x(25). Divide both sides by 25 to get 60
Multiply total number (12) by the fraction that like dogs (1/3).
=12 total * 1/3 dog people
=(12*1)/3
=12/3
=4 dog people
ANSWER: There are 4 people who like dogs the best out of the 12 surveyed.
Hope this helps! :)
The Charles current age is 10 years old, if in 20 years Charles will be three times as old as he is now.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
In 20 years, Charles will be three times as old as he is now.
Let's suppose the current age of Charles is x years
Then, according to the problem, we can frame a linear equation in one variable:
x + 20 = 3x
2x = 20
x = 10 years
Thus, the Charles current age is 10 years old if in 20 years Charles will be three times as old as he is now.
