elena55 [62]

Answer:

We obtain same product by both the methods.

Step-by-step explanation:

We are given the following in the question:

Commutative property of multiplication:

$\dfrac{3}{4}\times 4 =4\times \dfrac{3}{4}$

Different ways to find the product:

1. First way

$\dfrac{3}{4}\times 4\\\\=3\times \dfrac{4}{4}\\\\=3$

2. Second way

$\dfrac{3}{4}\times 4\\\\=\dfrac{12}{4}\\\\=3$

We get the same product for both the calculations.

Anna and Maya are competing in a dance tournament where dance moves are worth a certain number of points if a dance move it's do

Gre4nikov [31]

Anna's current number of points = 225 points.

She danced correctly and earned = 75 points.

And when she danced incorrectly she loses = 30 points.

Note: For dancing correctly earned points will be added and for dancing incorrectly loses points will be subtracted from the total points has in starting.

So, we can setup an expression as

Current points + earned points - loses points

Plugging values, we get

225 +75 -30 Required expression.

Adding 225 and 75, we get 300.

Therefore, 225 +75 -30 = 300-30.

Subtracting 30 from 300, we get

300-30=270.

Therefore, Anna's final score is 270 points.
