The terms appear to increase by a multiple of -2. The first 7 terms are:
-4 + 8 + -16 + 32 + -64 + 128 + -256. Add these together.
The sum of these numbers is -172.
Into? Is hard to answer without the rest of the problem
It is 4000 that is the correct answer
Simple Interest formula is :
, where I = Amount of interest, P= Principal amount, r = rate of interest in decimal and t = time duration in year.
Given in the question that, P = $800 and r =
% = 4.75% = 0.0475
<u>a.</u> For t =
year ....

So, Jada will receive $19 interest at the end of 1/2 year.
<u>b.</u> For t = 1 year ....

So, Jada will receive $38 interest at the end of 1 year.
Answer:
Since all three of the interior angles are the same degree, the three sides must be the same length. So, 3x - 5, 4x - 30, and 2x + 20 must be equal.
To solve for x, you can just set one of the sides equal to another one of the sides. I will do 3x - 5 and 4x - 30.
3x - 5=4x - 30
Add 5 to both sides.
3x = 4x - 25
Subtract 4x from both sides.
-x = -25
Divide both sides by -1.
x=25
