Answer: D) -3x + 11xy

Step-by-step explanation:

Given expression= $3xy+10xy-5x+2x-2yx$

To find which expression is equivalent to the given expression, we need to first combine like terms, we get

$3xy+10xy-2xy-5x+2x\\=13xy-2xy-3x\\=11xy-3x$

This is equivalent to $-3x+11xy$

Hence D is the right answer, the given expression is equivalent to $-3x+11xy$ .

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{40}}}}}$

Step-by-step explanation:

$\sf{50 \: \% \: of \: 80}$

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒ $\sf{ \frac{50}{100} \times 80}$

⇒ $\sf{ \frac{1}{2} \times 80}$

Divide 80 by 2

⇒ $\sf{40}$

Hope I helped!

Best regards!!
