imconfuse with this stuff. im just sayin it as it is in the book. its my homework.

The answer is 9.You solve it as:2x-9=x2x-x=9x=9
twice the difference of three times a number and eight
what is 10 squared DOES NOT equal what?
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
The inequality representing "twice a number is at least 15" can be expressed as ( 2x \geq 15 ), where ( x ) is the unknown number. To solve for ( x ), you would divide both sides of the inequality by 2, resulting in ( x \geq 7.5 ). This means that the number must be 7.5 or greater to satisfy the condition.
To write "twice a number plus six is greater than nine" as an inequality, let the number be represented by the variable ( x ). The expression can be written as ( 2x + 6 > 9 ). This inequality states that when you multiply the number ( x ) by two and then add six, the result is greater than nine.
If the number is n then twice the number is 2n and 7 less than twice the number is 2n - 7This could also be a boolean variable based on another variable. If the number is less than or equal to 3.5, the variable is false. Otherwise, it is true.
The difference between a number x and twice y is equal to fifteen.
The statement "twice number x is at most -3" can be expressed mathematically as (2x \leq -3). This means that the value of (x) must be less than or equal to (-\frac{3}{2}) or (-1.5). Therefore, the inequality indicates that (x) can take values that are (-1.5) or lower.
A + 2a = 3a
composite number
Simple! The number is 0.
um, 9.

Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.Since you need a specific number - the number 6 - twice, the probability is (1/6)2, which is equal to 1/36.
