21. 1,600 people rode that afternoon: 8 rows times 4 people * 50
It would be 12 because 7 is higher than 5 and so you would round 11.751 to 12
I hope this helped :) <3
(Sorry if this is wrong)
To solve both of these expressions, we want to add or subtract from left to right.
For the first one, we can rewrite it as:
8-6-9
=2-9
=-7
The second one we can rewrite as:
5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11
Check the picture below.
a rhombus is a quadrilateral with all equal sides.
now, the sides do not have to be slanted, but they must be equal, IF it happens that all sides meet at right-angles, then the rhombus is a "rectangle", due to its right-angleness, incidentally enough, since all sides are equal, if that ever happens, it also becomes a square.
Don't take my word on this, I'm just trying to help. I think -14 represents the cold tempature and 0 represents the hot tempature
