To simplify this expression you would need to distribute.

5 (m +3 +n) = 5m +5n +15

You are given the system of equations to solve by the elimination method, which is an INCORRECT step that will NOT produce a sys

Karo-lina-s [1.5K]

C would be the correct answer. You caanot multiply just one part of an equation, you must multiply the whole thing. All of the other steps follow this rule, so C is an incorrect step, and is therefore the correct choice.

Hope this helps!

Given:

$|3+4 i|+|3-4 i|+|-3+4 i|+|-3-4 i|$

Solution:

Complex formula:

$|a+b i|=\sqrt{(a+b i)(a-b i)}=\sqrt{a^{2}+b^{2}}$

Let us simplify one by one.

$|3+4 i|=\sqrt{3^{2}+4^{2}}$

$=\sqrt{25}$

|3 + 4i| = 5

$|3-4 i|=\sqrt{3^{2}+(-4)^{2}}$

$=\sqrt{25}$

|3 - 4i| = 5

$|-3+4 i|=\sqrt{(-3)^{2}+4^{2}}$

$=\sqrt{25}$

|-3 + 4i| = 5

$|-3-4 i|=\sqrt{(-3)^{2}+(-4)^{2}}$

$=\sqrt{25}$

|-3 - 4i| = 5

Substitute these in the given expression:

$|3+4 i|+|3-4 i|+|-3+4 i|+|-3-4 i|=5+5+5+5$

$=20$

The solution of the expression is 20.

The population of a small town was 10,800 in 2002. Since then the population has decreased at a rate of 2.5% each year. Write an

lozanna [386]

Answer:

See below

Step-by-step explanation:

A 2.5 % decrease means 97.5 % remains (.975)

population = 10800 ( .975) ^n where n = years past 2002

in 2020 n = 18

10800 (.975)^18 = 6847 people

A man gets Rs. 40 for everyday he works, but is fined Rs. 10 for everyday he is absent If he got Rs. 700 at the end of 30 days.

The number of days he was absent from work will be 50 days

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a man gets Rs. 40 for every day he works, but is fined Rs. 10 for every day he is absent If he got Rs. 700 at the end of 30 days.

The number of days he was absent from work will be calculated as below:-

40×300 = 1200

= 1200-700

= 500

1 day is 10 then 50 days is 500. Therefore, the number of days he was absent from work will be 50 days
