<h3>Answer:</h3>
A. If two lines intersect and form right angles, they intersect and form 90° angles.
<h3>Explanation:</h3>
The first conditional can be described by ...
... if p then q
where
- p = two lines intersect and form right angles
- q = the lines are perpendicular
The second conditional can be described by ...
... if q then r
where
- r = they intersect and form 90° angles.
___
The Law of Syllogism tells us that we can conclude ...
... if p then r
where p and r are as defined above. This translates to ...
... If two lines intersect and form right angles, then they intersect and form 90° angles. (matches selection A)
Given:
Markers are sold in packages of 12 and pens are sold in packages of 8.
To find:
Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens
Solution:
To find the least amount of markers and pens, we need to find the LCM of 12 and 8.
Prime factors of 8 and 12 are


To find the LCM, multiply all factors but the common factors are included only once.


Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.
1/3+2/5+4/3+3/5=8/3
Steps
A double negative makes a positive.
So, change all double negatives to positives (to simplify it)
1/3 + 2/5 + 1+1/3 + 3/5
What's the least common denominator here?
Yes, it is 15!
Change the fractions to that denominator
5/15 + 6/15 + 1+5/15 + 9/15
change 1+5/15 to 20/15, then add the fractions
Result: 40/15
Divide numerator and denominator both by the greatest common factor:5
8/3
