Answer: 4:15
Step-by-step explanation:
Ummmm i believe your answer is A. just divide next time :)
Answer:
l( longer side ) = 12cm
S (shorter side) =9cm
D's( distance between the shorter side). ( It is also the height. I hope you got the clue…)
Anyway,
Area=9X8=72cm^2
Distance of the longer sides is
Area/the length of the longer side
72/12=6cm…
Distance between the longer sides is 6cm
Hope this helps…
So the total number of students equals 8+17 = 25 students
Proportionally:

Thus,

boys out of the 100 students.
Answer:
y=2
Step-by-step explanation:
First, you substitute x with 2.
3(2)-6y=(-6)
Then, you multiply:
6-6y=(-6)
Next, you subtract 6 from -6. So, the first 6 gets crossed out because of inverse of operation.
-6y=-12
Finally, you divide -6 to both sides of the equation to get y=2
