1 answer:
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

Y+4<u><</u>9
subtract 4
y<u><</u>5
y is smaller than and equal to 5
so you shade from 5 to the negative end to infinity (to the left) and shade the 5 to show that it is included (attachment says A)
6 less than (-6) 2 times a number (2 time x) is greater than (>) 8 (8)
-6+2x>8
add 6
2x>14
divide 2
x>7
so
x is bigger than 7
shade from 7 to the positive end to infinity (to the right) and don't shade 7 but put a circle around it to show that it is not included (attachment says B )
