Question:

Simplify -2¹/9 – -4⅓

Answer:

-2¹/9 – -4⅓ when simplified is 20/9

Step-by-step explanation:

Given

Simplify -2¹/9 – -4⅓

First, we need to convert both fractions from mixed fraction to improper fraction

-2¹/9 = -(18+1)/9

-2¹/9 = -19/9

-4⅓ = -(12+1)/3

-4⅓ = --13/3

So, -2¹/9 – -4⅓ becomes

-19/9 - - 13/3

-19/9 + 13/3

Find LCM of both fractions (9)

(-19 + 39)/9

20/9

Hence, -2¹/9 – -4⅓ when simplified is 20/9

Lucy earns money babysitting. Her earnings and hours worked represent a direct variation. She worked for 4 hours and earned $25.

SashulF [63]

For this case we have that by definition, a direct variation is given in the form:

$y = kx$

Where:

k: It is the constant of proportionality

According to the statement we have to:

$y = 25\\x = 4$

Substituting:

$25 = k4\\k = \frac {25} {4}$ $k = 6.25\ for\ \frac {dollars} {hour}$

On the other hand we have:

$y = 4\\x = 25\\4 = k25\\k = \frac {4} {25}$

$k = 0.16\ for\ \frac {hours} {dollar}$

Answer:

$k = 6.25 for \frac {dollars} {hour}\\k = 0.16 for \frac {hours} {dollar}$
