So to find an average of things, you find the sum of the numbers, divided by the total numbers in the set.
So you add up 258 + 50 = 308.
Divide that by the total numbers (2). 308/2 = 154
This is the concept of algebra, we are required to subtract the complex numbers. Thus;
(5-2i)-1(1+8i)
opening the brackets using the distributive property we get:
5-2i-1-8i
collecting the like terms we get:
5-1-2i-8i
=4-10i
the answer will therefore be:
4-10i
Answer:
Cool!
Step-by-step explanation:
I did not know that! Isn't that a brainly fun fact?
Brainliest appreciated!
Simplifying
(x + -16) * 2 = 256
Reorder the terms:
(-16 + x) * 2 = 256
Reorder the terms for easier multiplication:
2(-16 + x) = 256
(-16 * 2 + x * 2) = 256
(-32 + 2x) = 256
Solving
-32 + 2x = 256
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '32' to each side of the equation.
-32 + 32 + 2x = 256 + 32
Combine like terms: -32 + 32 = 0
0 + 2x = 256 + 32
2x = 256 + 32
Combine like terms: 256 + 32 = 288
2x = 288
Divide each side by '2'.
x = 144
Simplifying
x = 144
