Answer:
$5 bill
Step-by-step explanation:
If Rhonda has $13 and she has a $5 bill and 3 $1 bills, then she has
5 + 3(1) + x = 13
5 + 3 + x = 13
8 + x = 13
x = 5.
The last bill must be a $5 bill to equal the remaining $5.
we don't know what the value of "X" is, so therefore, we cannot conclude that it is 15 cm.
3,000 feet i think since the formula is width *height *length so it should be correct.
