Answer: The property which is illustrated by the given equation, is associative property of addition.

Explanation:

The associative property of addition states that the sum of three real number remains the same either start addition from first two numbers or last two numbers.

(a+b)+c=a+(b+c)     ... (1)

The given equation is,

(2+x)+3=2+(x+3)

The above equation is same as equation (1)0, where the value of a, b and c are 2, x and 3 respectively.

And after simplifying the given equation we get,

5+x=5+x

The left hand side is equal to right hand side. So, the associative property of addition is illustrated by the given equation.

Question 6
inna [77]

Answer:

add, subtract, multiply and divide complex numbers much as we would expect. We add and subtract

complex numbers by adding their real and imaginary parts:-

(a + bi)+(c + di)=(a + c)+(b + d)i,

(a + bi) − (c + di)=(a − c)+(b − d)i.

We can multiply complex numbers by expanding the brackets in the usual fashion and using i

2 = −1,

(a + bi) (c + di) = ac + bci + adi + bdi2 = (ac − bd)+(ad + bc)i,

and to divide complex numbers we note firstly that (c + di) (c − di) = c2 + d2 is real. So

a + bi

c + di = a + bi

c + di ×

c − di

c − di =

µac + bd

c2 + d2

µbc − ad

c2 + d2

50 didved by what will get 5,000
DENIUS [597]

Answer:

0.01

Step-by-step explanation:

Your equation is 50 / x = 5,000

You are able to switch this around to 50 / 5,000 = x

Because you know that a x b = c is the same as b x a = c

When you divide 50 by 5,000, you get 0.01

So, 50 divided by 0.01 will get 5,000

Step-by-step explanation:

A school bus has 25 seats, with 5 rows of 5 seats.

15 students from the first grade and 5 students from the second grade travel in the bus.

second-grade students occupy the first row.

The 5 students of second grade are to be seated in 5 seats,this can be done in:

5P5 ways where P is the permutation

Now 15 students from first grade are to be arranged in remaining 20 seats

This can be done in:

20P15 ways

Hence, total ways student can be seated is:

5P5×20P15
