18 - 3n
Let x be the number and so it is: 3x-18
As an expression it is: 18-3d
y < 18 x 6
It is an algebraic expression
The expression is: ab-18
As the subtraction is done first, it needs to be in brackets; thus eighteen decreased by four then times three is: (18 - 4) × 3
It is an algebraic expression involving the variable, v.
It is an algebraic expression because it does not contain an equality sign.
It is an algebraic expression that can be simplified to: 45x -16
As an algebraic expression it is simply: 18-x
change the algebracic expression into a word phase 18+s
3n+18 is an algebraic expression and n is an unknown variable
You may need to rephrase the question but if you mean this - 18 = 3d so what's d? Then the answer is 18 divide by 3 so 6
When 18 is decreased by (-27), the result is 45.
x-18=5 times -5 x-18=-25 x=-25+18 x=-7
Not sure what the question means, but the answer is either one of the following two: (a) 18 * 18 = 182 (b) 18 * 18 = 324 = 3.24*102
It is 18/n.
Cut in half, decreased by 50%.
