Answer:
1.35cm
Step-by-step explanation:
Given the scale of the map
1cm = 100km
For 135km;
x cm = 135 km
Divide both equations
1/x = 100/135
100x = 135
x = 135/100
x = 1.35cm
Hence the map distance will be 1.35cm
Answer:
X=3
Step-by-step explanation:
If you do the problem backwards 14-5=9 and 9/3 is 3, so x=3 plug it in and check if it is correct, 3*3+5=14
Try creating a proportion, take 12/21=x/15
you should have gotten x=8.571
P.S.: hope I helped

they both have the same interquartile range so it’s A.
Answer:
a.) 13 students
b.) 53 members
Step-by-step explanation:
a.) In the given equation of y=4x+13, "x" represents how many years have gone by since the club had started. The number "13" in this equation represents the y-intercept, or the value of "y" when x = 0. Therefore, when "x" is 0 years, there were 13 students in the clubs, meaning that the original group that started the club contained 13 students.
b.) Since the question asks how many members that the club will have after their tenth year and you already know that "x" in the equation y=4x+13 represents the number of years since the club started, all you have to do is plug 10 in for "x" in the equation; so, the equation will now look like this: y=4(10)+13. Keeping PEMDAS in mind, you first multiply 4 and 10 to get 40, and then you add 13 to get an answer of 53 members after year 10.
