Answer:
x=5
Step-by-step explanation:
so we know the final number is 6 so lets look at the rest of the question:
"twice the difference" so we are going to double the difference of two numbers, one we don't know (x) and the other is 2, so lets put this together and solve:
2(x-2)=6, x-2=3, x=5
Let's just make 15 students a group. how many groups are there if there r 135 student? 135/15 = 9 groups.
so if each group have 4 adults just multiply 9 by 4,
therefore there will be 36.adults.
Option A
If f(x) =
and g(x) =
then 
<em><u>Solution:</u></em>
Given that f(x) =
and g(x) = 
To find: (f - g)(x)
We know that,
(f – g)(x) = f (x) - g(x)
Let us substitute the given values of f(x) and g(x) in above formula,

For solving the brackets in above expression,
There are two simple rules to remember:
When you multiply a negative number by a positive number then the product is always negative.
When you multiply two negative numbers or two positive numbers then the product is always positive.
So the expression becomes,

Combining the like terms,

Thus option A is correct
Step 1: Add 65 to all sides
Step 2: Add 4x to all sides
Step 3: subtract 70 to all sides
Step 4: divide by 4 to all sides
Ending: x is greater than or equal to -17.5
You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...
No solution because the inequality that you end up with won't make sense and therefore does not work in the problem
