Z=12
"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
The algebraic expression for 84 divided by the number ( z ) is ( \frac{84}{z} ). This expression represents the quotient of 84 and the variable ( z ).
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.
To write the difference of ( z ) and 8 as an expression, you would subtract 8 from ( z ). This can be expressed mathematically as ( z - 8 ). This expression represents the value obtained when 8 is taken away from ( z ).
z + 8 - 2 is an expression, not an equation. An expression cannot be solved. At best, you can simplify it to z + 6.
It is: z-8
z/.07
z+7
The algebraic expression for the quotient of 3 and the sum of z and 5 is 3 / (z + 5). In this expression, the numerator is 3, and the denominator is the sum of z and 5. This expression represents dividing 3 by the sum of z and 5.
The expression "3 divided by z" is represented mathematically as ( \frac{3}{z} ). The result depends on the value of ( z ); as long as ( z ) is not zero, this expression will yield a numerical value. If ( z = 0 ), the division is undefined.
