Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5
X= 13.5
Every triangle equals 180 degrees. 23+23= 46. 46 - 1= 45. Then you solve the equation 10x+45=180 which would equal, 13.5.
Answer:
it toke hoh 3 minutes to trave
Step-by-step explanation:
since the given is 48 cm (distance) and 16cm per minute ( speed )
the equation for that is distance over speed
