Answer:
168
Step-by-step explanation:
photos are enlarged by a certain factor, divide the new width by the old width and youll get the factor (12).
You can then multiply the original height by 12 to get the answer
12 X 14 =168
2x - 3y = - 2
3x - 2y = 12
the value of X in the solution to the system is 4.
Answer:
You need to find the average for your numbers
Step-by-step explanation:
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.
