Answer = 0
n can have possible values from (-12) to 12
-12 <= n < 12
(-12) + (-11)+(-10)......+10+11+12=0
C in my opinion

I would say to check the 1st and 3rd
Answer:
5% account = $1,240
10% account = $2,190
Step-by-step explanation:
Let's assume the amount of savings in the 5% account is x.
Thus the amount of savings in the 10% account is (x + $950).
We can write the following equation from the interest amount:
[5% x ] + [10% (x + $950)] = $281
5%x + 10%x + $95 = S281
15%x = $186
x = $1,240
There is $1,240 in the 5% account
Therefore, on the 10% account there is $1,240 + $950 = $2,190
Answer:
40
Step-by-step explanation:
*this is a 90 degree triangle
so we will use Pythagorean theorem to get X
hypotenuse²=side of right triangle²+the other side of right triangle²
so
50²=30²+x²
2500=900+X²
2500-900=x²
1600=x²
x=√1600
=40
so the answer is 40
