The number of $5 notes is 10 and $50 notes is 6
Step-by-step explanation:
Let x be the number of $5 notes
and
y be the number of $50 notes
Then according to given statements
"The total number of notes used was 16."
x+y=16 Eqn 1
"A restaurant bill of $350 was paid using $5 notes and $50 notes."
5x+50y=350 Eqn 2
Putting x=10 in equation 1
So,
The number of $5 notes is 10 and $50 notes is 6

Explanation :
II. False. a rectangle is a special type of rhombus since a rhombus has all sides equal, while a rectangle has all angles equal. A rhombus has opposite angles equal, while a rectangle has opposite sides equal. The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.
I. True. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.
III. False. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.
