Hi there!
Here we go:
2x + 1 ≤ 
You need to multiply each side of the equation by 2
4x + 2 ≤ 3(x + 1)
You need to distribute the 3 to the entire parentheses
4x + 2 ≤ 3x + 3
You need to subtract 3x from each side of the equation
x + 2 ≤ 3
You need to subtract 2 from each side of the equation
x ≤ 1
There you go! I really hope this helped, if there's anything just let me know! :)
Answer: 2,72 and 72, 2
Step-by-step explanation:
Aritmetic has a common difference
-27 to -12 is a difference of 15
-12 to 3 is a difference of 15
an=a1+d(n-1)
a1=first term
d=common difference
fist term is -27
common difference is 15
an=-27+15(n-1)
84th term is n=84
a84=-27+15(84-1)
a84=-27+15(83)
a84=-27+1245
a84=1218
the 84th term is 1218
So, we need to consider what is being done.
So, lets start with the -3.
-3*
Now, lets see what's next
2 times a number is the same as saying 2x, then add one.
That is equal to five.
-3(-2x+1)=5
Now,
6x-3 = 5
6x = 8
x= 8/6
Answer:
x = -15
