Answer:
x = 2.17975706
Step-by-step explanation:
sin(x +sin(x)) = 3sin
x(x-2)
sin(x) = 0 or sin(x) = 2
It’s definitely-20
Add 9 to both sides to cancel it out so it is now
4x-20=5x
Than subtract 4x on both sides it is now
-20=x
Because 5-4 equals 1 and 1x is just written as x
Answer:
c.....c......c
Step-by-step explanation:
equation csn be represented as
money left = 500 - (n-1)×4.65
so we can see in first week money left
= 500 - (1-1)×4.65= 500-0=500
which is true because first week chaya got gift card and does not spend any money.
now lets assume that on week n money left is 327.95
so by equation
500 -(n-1)×4.65 = 327.95
500- 327.95 =( n-1)× 4.65
n -1 = 172.05/4.65=37
n = 37+1 = 38
in 38th week money left would be 327.95
