Answer:
SUE: (18-x)-5
TONY: (18+x) / 
Sue has 18 sweets
Tony also has 18 sweets
Sue gives x sweets to Tony
Sue then eats 5 of her sweets
Tony then eats half of his sweets
(18-x)-5=(18+x)/ 1/2
x= -7.6
Remark
What you have to do to learn the difference between recursive and explicit is try try the first 3 or 4 terms to see what you have and how you did it.
a1 = - 3
a2 = - 3 (1/8) = -3 / 8
a3 = (a2) (1/8)
a3 = (-3/8) * 1/8
a3 = (- 3/64)
a4 = a3 (1/8)
a4 = -3/64 * 1/8
a4 = - 3 / 512
Take a good look at a4. What do you notice? No matter what, you are always multiplying by 1/8. That means that A and D are both wrong which they would have you raising by 3 or - 3 to some power.
So which one of B and C is correct?
The answer is which ever one will not change sign from what it started out with. All four terms are minus.
In B the term is multiplied by plus 1/8. That will not change the sign of the next term.
So the answer is
a_n = - 3 * (1/8)^(n - 1) <<<<< answer
Answer:
zx=115'
Step-by-step explanation:
supplementary angles add up to 180'
180-65=115
The value of <u>a</u> is 2 and the value of <u>b</u> is 6.
<h3>Factoring</h3>
In math, factoring or factorization is used to write an algebraic expression in factors. There are some rules for factorization. One of them is a factor out a common term for example: x²-x= x(x-1), where x is a common term.
You should factor the given expression.
