<u>The error is that they had placed the numbers in the wrong placeholder.</u> Remember that the Distance formula is D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} .

<em><u>Correct Work:</u></em>

D=\sqrt{(5-(-1))^2+(16-15)^2}\\D=\sqrt{6^2+1^2}\\D=\sqrt{36+1}\\D=\sqrt{37}\ \approx 6.08

A student has $1 bills and $5 bills in his wallet. He had a total of 15 bills that are worth $47. How many of each type does he
Mrrafil [7]

Total number of $1 bills=7

Total number of $5 bills=8

Further explanation:

Given

Let x be the number of $1 bills

and

y be the number of $5 bills

Then according to the given statements

x+y=15

x+5y=47

From first equation:

x+y=15\\x=15-y

Putting x=15-y in second equation

x+5y=47\\15-y+5y=47\\4y=47-15\\4y=32\\\frac{4y}{4}=\frac{32}{4}\\y=8

Putting y=8 in first equation

x+8=15\\x=15-8\\x=7

Hence,

Total number of $1 bills=7

Total number of $5 bills=8
