First of all, to find the slope, you need to subtract the y's in the numerator over the x's in the denominator. Then you use Y-Y₁=slope(X-X₁) using either of the two points. If you want to simplify it further into slope-intercept form, you need to distribute on the right side of the equation.

Okay so let’s start by figuring what the total number of people is. To get that we add 24 and 30.
24+30= 54
So we have a total of 54 people.
Now, how many children are there?
30 children... which means the ratio is 30:54
Thirty children to fifty four people total at the museum.
Hope this helps!

Answer:
9/5 miles in 1 hour
Step-by-step explanation:
As we are finding here the miles distance in 1 hour so we have to use here the formula which is
Rate = Distance / Time
Rate = 3/5 divided by 1/3
SO using third proportion rule we have to change the Numerator of second fraction with denominator and denominator with numerator and division sign will be change into Multiplication so this one will be
3/5 x 3/1
9/5 will be the answer
