Robert bought $1.60 worth of stamps with 20 coins all in nickels and dimes. how many nickels and dimes did he use?

1 answer:

3 0

Nickels are 5 cents, and dimes are 10 cents.
(By luck..) eventually you can have 12 dimes, meaning you have 120 cents, or $1.20 ... 20-12=8.. meaning you used 12 dimes and are missing 8 more coins. which means you can have 8 nickels which is 40 cents. 120+40=160 cents or $1.60
Hope this helped.

The correct option is first option: x=t(y-4f)

Further explanation:

Given equation is:

$\frac{x}{t}+4f=y$

In order to solve the equation for x, we have to isolate x on one side of the equation

Using Subtraction property of equality

Subtracting 4f from both sides

$\frac{x}{t}+4f-4f=y-4f\\\frac{x}{t}=y-4f$

Multiplication property of equality

Multiplying both sides by t

$\frac{x}{t}*t=t(y-4f)\\x=t(y-4f)$

Hence, the correct option is first option: x=t(y-4f)
