<h2>Answer:</h2>

The property that is illustrated by the equation:

$2x+4y=4y+2x$ is:

Commutative Property.

<h2>Step-by-step explanation:</h2>

We know that for any relation R and for any set A.

If a,b belongs to A.

Then if a is related to b i.e. a R b

then by the commutative property we have:

b is related to a i.e. b R a

Here the terms 2x and 4y are related to each other by addition sign.

i.e. if 2x is related to 4y i.e. 2x+4y

then by commutative property 4y is related to 2x i.e. 4y+2x

Hence by commutative property , we have:

a+b=b+a

i.e. $2x+4y=4y+2x$

It’s a new semester! Students are grouped into three clubs, which each has 10, 4 and 5 students. In how many ways can teacher se

ozzi

Here we must see in how many different ways we can select 2 students from the 3 clubs, such that the students <em>do not belong to the same club. </em>We will see that there are 110 different ways in which 2 students from different clubs can be selected.

So there are 3 clubs:

Club A, with 10 students.
Club B, with 4 students.
Club C, with 5 students.

The possible combinations of 2 students from different clubs are

Club A with club B
Club A with club C
Club B with club C.

The number of combinations for each of these is given by the product between the number of students in the club, so we get:

Club A with club B: 10*4 = 40
Club A with club C: 10*5 = 50
Club B with club C. 4*5 = 20

For a total of 40 + 50 + 20 = 110 different combinations.

This means that there are 110 different ways in which 2 students from different clubs can be selected.

What is -1/2- (-2/5)=

Stolb23 [73]

= -1/2- (-2/5)
= -1/2 + 2/5
find common denominator (2 goes in 10 five times; 5 goes in 10 twice)
= -(5*1)/10 + (2*2)/10
= -5/10 + 4/10
= -1/10

Hope this helps! :)
