It’s b I did it I got it right
It must be true that a implies c, because of the transitive property.
If a is true, then b is true as well. But every time b is true, c is true as well.
So, "jumping" over b, we have that if a is true, c is true as well.
Think of this example:
- a: I live in Rome
- b: I live in Italy
- c: I live in Europe
It is true that
, because Rome is inside Italy, and similarly
, because Italy is a European state.
So, if I live in Rome, I must live in Europe as well.
X + 3x = 27
4x = 27
÷ 4
x = 6.75 (smaller number)
27 - 6.75 = 20.25 (larger number).
I don't know the 'systems of equations' though, sorry.
C. an isosceles triangle has 2 equal sides.
the reason b and d aren’t true is because the sides add up to be less or equal to the longest side and to make a triangle the 2 sides have to add up to be more than the longest side.
