X+x+2+x+2+2x-5=49
you would then combine all the x’s
which would equal 5x+2+2-5=49
the you would add up your numbers =ing
5x+-1=49
then add -1 to the other side of the = sign making the one positive which would equal
5x=50
divide by 5
x=10
Answer:
-4/5
Step-by-step explanation:
2/5 ÷ -1/2
Copy dot flip
2/5 * -2/1
-4/5
Step-by-step explanation:
(x-9)²
= (x-9)(x-9)
= x²-9x-9x+81
= x²-18x+81
Answer:
x = 100
Step-by-step explanation:
Both angles are equivalent. 150-50=100. There's your answer! :)
Answer:

Step-by-step explanation:
Given:
Fifth term of a geometric sequence = 
Common ratio (r) = ¼
Required:
Formula for the nth term of the geometric sequence
Solution:
Step 1: find the first term of the sequence
Formula for nth term of a geometric sequence =
, where:
a = first term
r = common ratio = ¼
Thus, we are given the 5th term to be ¹/16, so n here = 5.
Input all these values into the formula to find a, the first term.




Cross multiply

Divide both sides by 16



Step 2: input the value of a and r to find the nth term formula of the sequence
nth term = 
nth term =
