z/.07
x = 7z/100
z+7
-7
z - 7
(2z - 7)(z + 4)
It is an expression in three variables, x, y and z.
The equation z-19 time 34 is a verbal sentence. This a math problem.
(3z + 5)(z -7)
To simplify the expression (42 - 7(z - 3)), first distribute the ( -7 ) across the terms inside the parentheses: ( -7z + 21 ). Then, combine it with the 42: ( 42 + 21 - 7z = 63 - 7z). Thus, the simplified expression is (63 - 7z).
The algebraic expression for the quotient of ( z ) and ( 9 ) is ( \frac{z}{9} ). This expression indicates that ( z ) is divided by ( 9 ).
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 ).
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 ).
