If: 8+x = 17 Then: x = 9
Let the number you are looking for be x, than 3x+8 is the algebraic expression for 8 more than triple a number.
8+6(x)
"more than" means to add. "a number" is just a variable, let's say x. "is" means equal to (=). Therefore, your equation would be: x + 8 = -12 Now, to solve for x, subtract 8 from both sides: x = -20
The algebraic expression for "8 more than half a number" can be represented as ( \frac{x}{2} + 8 ), where ( x ) represents the unknown number. This expression first calculates half of the number by dividing it by 2, then adds 8 to the result.
If: 8+x = 17 Then: x = 9
x+8
x + 8. This is fairly simple, because if you are given a number x, which will begin your equation. Then you need to find out what 8 more than it is, which would mean to add 8. This gives you your answer of x + 8.
x+7
x+8
Let the number you are looking for be x, than 3x+8 is the algebraic expression for 8 more than triple a number.
8+6(x)
2x + 8 is 8 more than double the number x.
57
Such a number cannot exist sine the relationship "less than" is transitive. That is: 7 < 8 Then, if x < 7 it follows that x < 8.
x=7 or x=-1
X - 14 < 8 or x < 22
