Answer:

$5x-2y$

Step-by-step explanation:

$2x-(3y-2x-y-x)$

Distribute Negative Sign

$2x+-1(3y-2x-y-x)\\2x+-1(3y)+-1(-2x)+-1(-y)+-1(x)\\2x+-3y+2x+y+x$

Combine like terms:

$(2x+2x+x)+(-3y+y)\\5x+-2y\\5x-2y$

5x-2y is your final answer.

Catron evaluates the expression (negative 9) (2 and two-fifths) using the steps below.

Vlad [161]

Answer:

Catron's error is

"She did not follow order of operations"

Step-by-step explanation:

Catron evaluates the expression (negative 9) (2 and two-fifths)

That expression can be written as below

$(-9)(2\frac{2}{5})$

Catron's error is

"She did not follow order of operations"

The corrected steps are

Step1: Given expression is $(-9)(2\frac{2}{5})$

Step2: Convert mixed fraction into improper fraction

$(-9)(2\frac{2}{5})=(-9)(\frac{12}{5})$

Step3: Multiplying the terms

$(-9)(2\frac{2}{5})=-7\frac{-108}{5}$

Therefore solution $(-9)(2\frac{2}{5})=-7\frac{-108}{5}$
