Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin

Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470 Eqn 1

x = y+14 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330$

Dividing both sides by 30

$\frac{30y}{30}=\frac{330}{30}\\y=11$

Putting y=11 in Eqn 2

$x=11+14\\x=25$

There are 25 $10 bills and 11 $20 bills.

Stepping off a distance by counting your paces is generally a more precise method of measuring than using a measuring tape.

dimulka [17.4K]

Answer:

False

Step-by-step explanation:

It depends on the distance and the curvature of the path. It is a straight line between endpoints and the length is a reasonable multiple of the full length of the tape measure then the tape measure is more accurate. If on the other hand the terrain is rugged and/or curvy then there isn't much to choose between the two. I think you are intended to answer false. The question leaves a lot to be desired.
