The first one is A and the second one is B, hope this helps!!
Because 21 is more than 1
Step-by-step explanation:
3x+18+2x-5= -2x+-2+10
combining like terms
3x+2x+2x=5-2+10-18
7x=-5
x=-5/7
This is an arithmetic sequence, since it's pattern is +4.
n1 = 1
d = 4
n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.
Simple....
you have: (3.2*103)+(5.78*105)
You want to simplify it..but first remember your order of operations...
1.) Remove the parentheses-->>
(3.2*103)=329.6
and
(5.78*105)=606.9
Which leaves you with...
329.6+606.9=
=936.5
Thus, your answer.
