What is the answer to -243 equals 90-9x?
The value of x that solves the equation -243 = 90 - 9x is x = -12.
3x-1 equals 11 what is the value of x2 plus x?
3x-1=11 solves to x=4. Plug in 4 to get 42+4. The answer is 20.
How are proportions related to direct variations?
If two variable, X and Y are in direct variation, then the proportion of X/Y or Y/X has a constant value.
What value does the following roman numeral have L X X X I X?
89
What is an inverse proportion relationship?
An inverse proportion between two variables is when the value of one variable increases, the other decreases. Mathematically, this is shown as: x = k / yn where x and y are the two variables, and k and n are constants.
What is the answer to -243 equals 90-9x?
The value of x that solves the equation -243 = 90 - 9x is x = -12.
Which proportion can be used to determine the value of x?
8/10
Can proportion be nagative value?
No. A proportion is the relationship of one part of something to the whole thing. If X is a fifth of Y, this must be a positive value.
What is a direct proportion?
Two quantities x and y are said to be in direct proportion if whenever the value of x increase (or decrease), then the value of y increases (or decrease) in such a way that the ratio x/y remains constant.

What is the constant of proportionality in math?
If two variables, X and Y, are in direct proportion then Y = c*X for some fixed value c. This value, c, is the constant of proportionality for this relationship.

What is the value of the x variable in the solution to the following system of equations?
x isn't a value, just a variable standing for a number
Solve for x in the following three over fourteen equal x over eighty four?
3/14 = X/84 Cross multiply the proportion: 14X = 252 X = 252/14 = 18.
What is 6.9 equals x plus 4.3?
It's a simple linear equation in 'x'.If you'd like to know the value of 'x' that solves the equation, you can find it like this:x + 4.3 = 6.9Subtract 4.3 from each side:x = 2.6See ?
