This means that Nathan's average speed was 12 miles per hour.
Step-by-step explanation:
54 divided by 4.5 is 12
this needs a system
140=5x+10y
y= 2x-1
Now subsitute 2x-1 in for y
140=5x +10(2x-1)
140 = 25x -10
bring over the 10
150 = 25x
the divide
x = 6
now substitue x in in 2x-1
2(6) -1 = 11
there you have it, you have 6 five dollar bills and 11 ten dollar bills.
