=-30
-2*-3=6
-1*5=-5
6 x -5=-30
Answer:
- <em>Yes, an answer can be incorrect even it it looks reasonable.</em>
Explanation:
Yes, an answer can be incorrect even if it looks reasonable, for two main reasons:
- The assumptions (premises or statements) on which the reasoning is based are wrong.
- The reasoning sounds good but it is a fallacy.
To avoid the first condition you must be sure about the facts, which may be information from an experiment that you performed or from a source. In order for an answer be correct, make sure your premises are true.
Dealing with the second condition, a fallacy is an argument that seems strictly logical but is misleading: you must learn which reasonings are really valid; this is, that the conclusion unequivocally follows from the premises.
There are rules for the arguments to be valid, and that is the object of logic study.
Fallacies are sometimes used by those interested in supporting a point of view without having true reason on their side. You should have some knowledges about logic to avoid being victim of the fallacies, which can drive you to make wrong decisions.
Answer: The first one; Plus 5
Step-by-step explanation: The rest of the answers are all negative 5.
It would either be C or D I think.
Solving the algebraic equations given, the missing numbers in the boxes can be known as shown in the steps below.
Given the equation, ⅔(x - 1) = ⅕(2x - 3) + 1
First, apply the distribution property to open the bracket.
Thus:
⅔x - ⅔ = ⅖x - ⅗ + 1
⅔x - ⅔ = ⅖x + ⅖
- Subtract ⅖x from both sides
⅔x - ⅖x - ⅔ = ⅖
4/15x - ⅔ = ⅖
4/15x = ⅖ + ⅔
4/15x = 16/15
- Multiply both sides by 15/4
x = 16/15 × 15/4
x = 4
Given the equation, 3c - 3 + 2(3c + 1) = - (3c + 1)
- Open the bracket using distributive property
3c - 3 + 6c + 2 = -3c - 1
9c - 1 = -3c - 1
9c + 3c - 1 = -1
12c - 1 = -1
12c = -1 + 1
12c = 0
c = 0
