<span>|4x + 12| = 16
As it is in modulus function, it could be either +ve or -ve
4x+12 = 16 OR 4x - 12 = 16
4x = 16-12 OR 4x = 16 + 12
4x = 4 OR 4x = 28
x = 4/4 OR x = 28/4
x = 1 OR x = 7

In short, Your Answer would be either 1 or 7

Hope this helps!</span>

What is the ratio of quarters to nickels in a dollar

sleet_krkn [62]

For quarters we have:

$0.25x = 1$

Where,

x: number of quarters

Clearing x we have:

$x = \frac{1}{0.25}\\x = 4$

For nickels we have:

$0.05y = 1$

Where,

y: number of nickels

Clearing y we have:

$y = \frac{1}{0.05}\\y = 20$

Then, the ratio of quarters to nickels is:

$\frac{x}{y}= \frac{4}{20}$

Simplifying we have:

$\frac{x}{y} = \frac{1}{5}$

Answer:

The ratio of quarters to nickels in a dollar is:

$\frac{x}{y}= \frac{1}{5}$
