What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the product of 4 and number a be = P
Let the number to be multiplied be in set A = { 1 , 2 , 3 , 4 , 5 }
Now , the first number = 4
So , the equation will be
The product of 4 and any number a or any number in set A can be written as
a)
The product is P = 4 x a
Product P = 4 x 1
P = 4
It can be written as sum of two equal addends
P = 2 + 2
b)
The product is P = 4 x a
Product P = 4 x 2
P = 8
It can be written as sum of two equal addends
P = 4 + 4
c)
The product is P = 4 x a
Product P = 4 x 3
P = 12
It can be written as sum of two equal addends
P = 6 + 6
d)
The product is P = 4 x a
Product P = 4 x 4
P = 16
It can be written as sum of two equal addends
P = 8 + 8
e)
The product is P = 4 x a
Product P = 4 x 5
P = 20
It can be written as sum of two equal addends
P = 10 + 10
f)
The product is P = 4 x a
Product P = 4 x 6
P = 24
It can be written as sum of two equal addends
P = 12 + 12
Hence , Yes , the product of 4 and any number can always be written as a sum of two equal addends

hari purchased a camera for rs 1560 and sold ot at 5% loss. find hos loss amount
Answer:
[tex]SP = 1482[/tex]
Step-by-step explanation:
Given
[tex]CP = Rs. 1560[/tex] --- Cost Price
[tex]Loss = 5\%[/tex]
Required
Determine the selling price (SP)
This is calculated using:
[tex]\%Loss =\frac{CP - SP}{CP} * 100\%[/tex]
So, we have:
[tex]5\% = \frac{1560 - SP}{1560} * 100\%[/tex]
[tex]5 = \frac{1560 - SP}{1560} * 100[/tex]
Multiply through by 1560
[tex]1560 * 5 = \frac{1560 - SP}{1560} * 100*1560[/tex]
[tex]1560 * 5 = (1560 - SP) * 100[/tex]
[tex]1560 * 5 = 1560 * 100- SP * 100[/tex]
[tex]7800 = 156000- 100SP[/tex]
Collect Like Terms
[tex]100SP= 156000- 7800[/tex]
[tex]100SP= 148200[/tex]
Make SP the subject
[tex]SP = \frac{148200}{100}[/tex]
[tex]SP = 1482[/tex]
The selling price is Rs. 1482

Which of the following is equivalent to the complex number i^34 ?
Choose 1 answer:
А
1
B I
C
-1
D
-I
Given:
The complex number is [tex]i^{34}[/tex].
To find:
The value of given complex number.
Solution:
We have,
[tex]i^{34}[/tex]
It can be written as
[tex]i^{34}=i^{32+2}[/tex]
Using properties of exponents, we get
[tex]i^{34}=i^{32}i^{2}[/tex] [tex][\because a^{m+n}=a^ma^n][/tex]
[tex]i^{34}=i^{4\times 8}i^{2}[/tex]
[tex]i^{34}=(i^4)^8i^{2}[/tex] [tex][\because (a^{m})^n=a^{mn}][/tex]
We know that, [tex]i^4=1,i^2=-1[/tex].
[tex]i^{34}=(1)^8(-1)[/tex]
[tex]i^{34}=(1)(-1)[/tex]
[tex]i^{34}=-1[/tex]
The value of [tex]i^{34}[/tex] is -1. Therefore, the correct option is C.

A school reserved a banquet hall for the spring dance. In addition to a $100 deposit, each couple must pay $20. If the total cost of the banquet hall is $1, 140. Solve the problem arithmetically. Show the steps you used.
Answer:
The total number of couples attending the banquet was 52.
Step-by-step explanation:
Given that a school reserved a banquet hall for the spring dance, and that, in addition to a $ 100 deposit, each couple must pay $ 20, to determine the total number of couples attending if the total cost of the banquet hall was $ 1,140 is due perform the following calculation:

20X = 1140 - 100
X = 1040/20
X = 52
Thus, the total number of couples attending the banquet was 52.

8: A) Adjacent Angles
Step-by-step explanation:
Let's pretend the sides of a triangle are A B and C.
The third side of a triangle is always greater tham A-B and lesser than A+B. This is called the triangle inequality theorem.
For 7 and 8, we have three lines that come together at one point (adjacent angles), and the vertical angle postulate where two mirrored angles will always have the same angle.
