Answer:
200 x .18 = 36 pounds which is 16 kg, Is the correct answer.
Step-by-step explanation:
200 x .18 = 36
Answer:In this problem,
a
n
=x
a

=1
d=6−1=5
∴x=1+(n−1)×5
∴x−1=(n−1)×5
∴(n−1)=
5
x−1
∴n=

x−1
+1
∴n=

x−1+5
∴n=

x+4
Equation (1)
2) Sum of n terms of A.P. is
∑a
n
=

n
[2a+(n−1)d]
As given in problem, ∑a
n
=148
∴

n
[2a+(n−1)d]=148
∴

∴

∴

[2+x−1]=148
∴

[x+1]=148
∴(x+4)(x+1)=1480
∴x

neglecting negative root, we get,
x=

Step-by-step explanation: i hope it was helpfu;;
I believe you are referring to exponents that have a multiple of three. If so any number * three is a valid exponent in your case.
Answer:
10.4 hope this help ;) 77 x 10.4
Step-by-step explanation
