what us the algebraic expression for 359 more than Z

The normal way to write z times 19 in an algebraic expression is 19z.

In the algebraic expression above z is an unknown variable.

3q + 2z, although it could be 2*(3q+z)

3/z + 5

"decreased by" means "minus" 12 decreased by z means 12 - z It really is that simple.

8<19z

x = 7z/100

Twenty three fewer than a variable represented by z.

359 more than z is z plus 359 which is: z + 359

It could be: -3/8+4x-9z as an algebraic expression

The question consists of an algebraic expression. There is no equation nor inequality which may be solved.

84/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.

2z

A literal cofficient is any variable in an algebraic expression. For example, in "21xyz", x, y, and z are literal coefficients.In math, a coefficient refers to a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.

A number x is said to be a factor of another number y if x divides into y without remainder. More technically, there must exist a number z such that x*z = y. Factors need not be numbers, they can be algebraic expressions. For example, (p+1) is a factor of (p2 - 2p - 3) - - - which is (p+1)(p-3)

If the number is 'z', then five less than twice the number is ( 2z - 5 ).

substitute the values of the variable inside the algebraic expression.for example:find the value of x when y = -4, z= 2, a=3, z= 00.5x + y -z (a+b)= 80.5x -az -bz +y = 80.5x -4=80.5x= 4x= 4/0.5= 8

m(a + b) = ma + mb distributive property (a + b)(c + d) = a(c + d) + b(c + d) The use distributive prop. twice. (c + d)(x + y + z) = c(x + y + z) + d(x + y + z) Still use dist. prop. etc. These work for subtraction as well.

3(z+15)

z + 12
