We are given:
2x + 5 - 3x = 8(x + 1)
We can start with several things. First, we can combine the x terms on the left side of the equation, and apply the distributive property on the right side of the equation.
5 - x = 8x + 8
Now, we can add x to both sides, and subtract 8 from both sides to isolate the variable.
5 - x = 8x + 8
-8 + x + x -8
We end up with:
9x = -3
By dividing both sides by 9, we get x =
.
If you want to check your answer, just plug x in!
2(
) + 5 - 3(
) = 8(

= 
As you can see,
=
as a result of having x =

Answer:
2/3, 0.6, 1/2, 0.12
Step-by-step explanation:
1/2, 0.12, 2/3, 0.6
im going to switch each to decimal if it isn't already
1/2 = 0.5
2/3 = 0.666 repeated
so now we have
0.5 , 0.12, 0.666 repeated, 0.6
now im going to put them in order
0.666 repeated, 0.6, 0.5, 0.12
now im going to change them back
2/3, 0.6, 1/2, 0.12
Answer:
more than 200 calls
Suppose number of calls = x
According to plan 1: Total monthly charge is $24
According to plan 2: Fix charge is $16 and $0.04 per call
cost of x's call = $0.04x
and monthly charge according to plan 2 = 0.04x + 16
a) Plan 1 is more economical than plan 2.
0.04x + 16 > 24
solve it for x
.04x > 8
x > 200
b) So, if more than 200 calls are made then Plan 1 is more economical.
