Answer:

Step-by-step explanation:
Use distributive property.

The answer is 60, cross multiply
The answer is a parallelogram. Quadrilateral have 4 sides, and if there are not right angles, it cannot be a rectangle because that is the added characteristic of rectangles. All rectangles are actually parallelograms, but only parallelograms will have exactly 2 pairs of parallel sides with no right angles. The statement says "may" because as I mentioned before, rectangles are parallelograms too!
Answer:
15 times there will be a blue and purple flag in the same spot
Step-by-step explanation:
300 miles / 10 miles = 30 blue flags in total
300 miles / 20 miles = 15 purple flags in total
There will be at least one blue flag for every purple flag. Since there is 15 purple flags in total, there will be 15 times this can occur.
I have attatched a demonstration of my thoughts to this post.
(3x + 1) + 44 = 90
(3x + 1) = (90 - 44) = 46
3x = 45
x = 45 / 3
x = 15
