Answer: A
Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3
Answer:3: If a linear system has the same number of equations and variables, then it must have a unique solution.
Step-by-step explanation:just this which correct
Inequalities are used to show the relationship between unequal expressions.
The inequalities that represent the maximum weights are:
- <em>2 axles - </em>
<em>.</em> - <em>3 axles - </em>
<em>.</em> - <em>4 axles - </em>
<em>.</em>
<em />
Let the maximum weight be represented with x
In inequality, maximum means less than or equal to i.e. 
<u>(a) 2 axles</u>
The maximum weight, here is 40000.
So, the inequality is:

<u>(b) 3 axles</u>
The maximum weight, here is 60000.
So, the inequality is:

<u>(c) 4 axles</u>
The maximum weight, here is 80000.
So, the inequality is:

Well, you can't have 4/3 of a rope because 3/3 would be one whole. That is an improper fraction. It would be 1 and 1/3. If you divide that in to two, then you get 2/3. Is that the answer you were looking for?
A fraction is bigger than a negative number. This is because, a negative number is below zero, while a fraction is greater than zero.
