3x+22=10x-41
-22 -22
----------------------
3x=10x-63
-10x -10x
-----------------
-7x=-63
divide by -7 on both sides
yep ur right its x=9
360 / 12 = 30
So, it's 30 degrees.
Incidentally, a 12 sided polygon is called a dodecagon.
The arithmetic sequence formula should help you
An= A1+ (n-1)d or An= a + d(n−1)
An= the term that you want to find.
A1 = first term in the list of ordered numbers
n = the term position (ex: for 5th term, n = 5 )
d = common difference of any pair of consecutive or adjacent numbers
So, looking the 4 choices you have the only one that follow the sequence of the formula is C
I believe the one you choose is Fibonacci sequence.
There different number of sequences:
1- arithmetic sequence
2- geometry sequence
3- Fibonacci sequence
Each of that sequences have their own formula.
So, the answer it might be C
Hope that help you
The formula for the Arithmetic is:
An = A1 + F x ( n- 1)
I believe answer is C
Because the one you chose is
Answer:
Answer : 52 girls
Step-by-step explanation:
Your ratio of boys to girls is 3:4
Set up a fractional proportion and cross multiply
3/4 = 39/x
cross multiply
3x = 4(39)
3x = 156
x = 156/3
x = 52 girls

5h - w = 170
for h = 77
w = 5h - 170
w = 5*77 - 170
w = 385 - 170
<span>w = 215
Shoutout to @himanshuchaturvedi
Your answer is : w = 215
Have an amazing day and stay hopeful!
