Answer:
6,162.50 JA
Step-by-step explanation:
Is this true?
72.50x80= 6,162.50 JA
Width = W
Length = 3 times w = 3W
Area = length x width = 3W * W = 3W^2
We draw 10 white tiles.
Then we shade in 9 of them.
We count the remaining tiles to get the answer, which is 1.
An aritmetic sequcne is represented as
where
an=nth term
a1=first term
d=common differnce, or how much each term increases by
n=which term
example
1,3,5, etc
first term is 1
common difference is 2 because it increases by 2 each time
so the formula would be
if we had
5,3,1
first term s 5
common difference is -2 since it goes up by -2 each time
so formula is
hope this helps
Let, Number of multiple choice = x
Number of short answer question = y
Now, x + y = 20
& 3x + 11y = 100
Multiply 1st equation by 3, and subtract from eq,2,
3x + 3y = 60
After subtraction,
8y = 40
y = 40/8
y = 5
Now, substitute in eq (1),
x + 5 = 20
x = 15
In short, There are 15 Multiple choice & 5 short answer questions
Hope this helps!
