Answer:
Step-by-step explanation:
I assume that XY is midsegment of a triangle, then MO = 2 XY
9x - 20 = 2( 3x - 4 )
9x - 20 = 6x - 8
3x = 12
x = 4
MO = 9(4) - 20 = 16 units
Answer: x = -9
Step-by-step explanation:
-10x - 10y = -10
when y = 10
-10x - 10(10) = -10
-10x - 100 = -10
Add 100 to each side
-10x = 90
Divide each side by -10
x = -9
-10(-9) - 10(10)
90 - 100 = -10
Hello
The answer is 45 people if you break down the equation you can get 60 -10 is 50 then subtract 5 to get 45 and you have your answer
Hope this helps
Plz mark me as brainist Thanks!!!!
Alright so lets start with an arbitrary amount of students. Just to help us visualize the problem.
Say, 100 students for the first year when it was founded?
So far,
1996 - 100 students
From 96' to 97', it doubles. So:
1996 - 100 students
1997 - 200 students
From 97' to 98', it doubles AGAIN.
1996 - 100 students
1997 - 200 students
1998 - 400 students
So, what the percentage increase from 100, to 400?
Well, 100 x 4 gives us 400, so it's a 400 percent increase.
