1 to 3 inches per week, is essentially, 1inch / 3weeks, which I believe is all you need to know.
So unit price times #of cloths=final price
unit price times 9=36.90
so 9x=36.90
divide both sides by 9
x=4.10
so D is the right answer
Answer:
B. False, because the description applies to a single solution. The solution set consists of all possible solutions.
Step-by-step explanation:
The choice of <em>true</em> or <em>false</em> revolves around whether a linear system can have more than one solution.
The problem statement does not say the equations are <em>independent</em>, a condition that must be satisfied if there is to be only one solution. Hence we must assume that the system may be dependent or even inconsistent, leading to zero, one, or an infinite number of solutions. The answer above carries its own explanation.
False, for the reason given
28 trucks/7 hours=4 trucks/1 hour.
Therefore A.) and B.) are incorrect.
The wording of these last two answers confusesme but I believe the correct one is D.) because 1 hour (per-/) 4 trucks.
Hope this helps!
