9x + -3 = 5x + -15
Reorder the terms:
-3 + 9x = 5x + -15
Reorder the terms:
-3 + 9x = -15 + 5x
Solving
-3 + 9x = -15 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-3 + 9x + -5x = -15 + 5x + -5x
Combine like terms:
9x + -5x = 4x
-3 + 4x = -15 + 5x + -5x
Combine like terms:
5x + -5x = 0
-3 + 4x = -15 + 0
-3 + 4x = -15
Add '3' to each side of the equation.
-3 + 3 + 4x = -15 + 3
Combine like terms: -3 + 3 = 0
0 + 4x = -15 + 3
4x = -15 + 3
Combine like terms: -15 + 3 = -12
4x = -12
Divide each side by '4'.
x = -3

You may represent this multiple ways.
1. 66/44 = m
2. 44m = 66
In both of these scenarios you have a total and equal parts.
The first one starts with a total and breaks it into equal parts.
The second choice shows 44 groups of a part totaling 66 meters.
Answer:
Step-by-step explanation:
If the roots are 1 + 5i and 1 - 5i, then you need the factors that result from those roots. They are (x - 1 + 5i) and (x - 1 - 5i). Now what you do with those is FOIL them out. Doing that gives you the following:
(what a mess, huh?)
The good thing is that several of those terms cancel each other out. +5ix cancels out the -5ix; -5i cancels out the 5i; and the 2 -x terms combine to -2x. That leaves you with:
Obviously you're in the section in math that deals with complex (imaginary) numbers so you should know that i-squared is equal to -1. Making that replacement:
a = 1, b = -2, c = 25
Answer:
Step-by-step explanation:
Given
Required:
Relationship between gallon and ounces
-- (1)
-- (2)
Multiply 2 by 2
--- (3)
The expressions in (1) and (3) are equivalent to 8 cups;
They can be combined to give:
Multiply both sides by 2
You mean 243 to the nearest hundred?
It's 200
Rule: (So that you can do it yourself) ^.^
If it's 4 or below, stay still
If it's 5 or above, add one
