"decreased by" means "minus" 12 decreased by z means 12 - z It really is that simple.
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.
Actually, 2x + 3y + z is an expression, because it is a mathematical noun.
The algebraic expression "twice a number z" can be represented as 2z. In this expression, the variable z represents the unknown number, and multiplying it by 2 gives you twice that number. This expression can be used in algebraic equations and formulas to represent scenarios where a number needs to be doubled.
z = 3. If you mean (4*z + 6 )/3 then it is 6. (4*3 + 6) /3 = (12 + 6) /3 = 18/3 = 6 If you meant 4*z + (6/3) then it is 14. 4*3 + (6/3) = 12 + 2 = 14.
"decreased by" means "minus" 12 decreased by z means 12 - z It really is that simple.
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.
x=y-8 z=x+12
If you mean z-9=3, then z=12. That means you can make any algebraic expression that makes sense. e.g. z+1=13.
z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
z/.07
It is: z-8
z+7
The normal way to write z times 19 in an algebraic expression is 19z.
Actually, 2x + 3y + z is an expression, because it is a mathematical noun.
what us the algebraic expression for 359 more than Z
Z is the answer of t increased by 5.
