What is FOR NO VALUE in math?
If an expression is true "for no value" of x, it means that there is no value you can substitute for x to make it true. For example, x=x+1 is true for no value of x, because x is always strictly less than x+1.
In order to make a porportions with two ratios what must be true about the ratios?
If there is a proportion a/b = c/d, then ad = bc. Examples: 3/4 =? 5/6 3 x 6 =? 4 x 5 18 = 20 False (this is not a proportion) 16/6 =? 8/3 16 x 3 =? 6 x 8 48 = 48 True (this is a proportion)
Find the value of x in the equation x plus 5 equals x plus 45?
There is no numerical value for 'x' that can make this a true statement.
How can you answer this equation for an addition equation like 2 x equals 5 how many values will make the equation true?
only one value will make the equation true: 2x = 5 x=5/2 x=2.5
What is x in the sum 9x plus 12 equals?
A variable like "x" can have any value. If you have a complete equation, like 9x + 12 = 100, a specific value of x will make the equation true; other values will make it false. But here, you don't have an equation, so any value will do for x.
What is FOR NO VALUE in math?
If an expression is true "for no value" of x, it means that there is no value you can substitute for x to make it true. For example, x=x+1 is true for no value of x, because x is always strictly less than x+1.
How can you tell if a proportion is true?
If you cross-multiply and you obtain an equality, then the proportion is true. Example: 2/3 = 20/30 ? cross-multiply; 2 x 30 = 3 x 20 ? 60 = 60 Since we have an equality, the proportion is true.
In order to make a porportions with two ratios what must be true about the ratios?
If there is a proportion a/b = c/d, then ad = bc. Examples: 3/4 =? 5/6 3 x 6 =? 4 x 5 18 = 20 False (this is not a proportion) 16/6 =? 8/3 16 x 3 =? 6 x 8 48 = 48 True (this is a proportion)
Find the value of x in the equation x plus 5 equals x plus 45?
There is no numerical value for 'x' that can make this a true statement.
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 value for x could make the sentence true?
It depends on the sentence.
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 value of x is 1 divided by x equal x percentage a true sentence?
so you are asking: When does 1/x = x% become true? It doesn't make sense. 1/x = x is true when x = 1 But it is never true with the percentage sign at the end.
What is a true proportion?
A true proportion is when two ratios are equal to one another. To prove this, you need to find the cross products of the ratios and see if they are equal. An example of a true proportion are the ratios 1/2 and 5/10, if you take the cross product the result is 2 x 5 = 1 x 10, which are equal.
What is the value in a math question?
Value is the number you're looking for that will make a math sentence true. Like x=2+5 x=7
How many different values for x make the equation x equals 5 true?
One, the value five.
