The initial value is 3. The common ratio is -9/3 = -3. The general formula is
.. an = a1*r^(n-1)
So, for your values, ...
.. an = 3*(-3)^(n -1)
Answer:
B
Step-by-step explanation:
let the angles be 3k,10k,2k
then 3k+10k+2k=180
15k=180
k=180/15=12
x=10k=10×12=120°
Answer:
If we’re dividing .31 by 9
The solution is on the photo below
Hope this helped. Have a great day!
-1 / 7 = x
You need to combine the 2x and 5x then devise the 7x from -1
When you have an equation that has variables and you know the value of those variables, just plug it it. So plugging the vaules we get
Just evaluating we get 4
