Great. A multiple choice question with no choices. Find the expression that equals 8.
Anything that equals 12.
Whatever expression equals 22.
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
-2-2 = -4

To find the equilibrium concentration of NO, first calculate the equilibrium constant expression using the given concentrations of O2 and N2. Then, rearrange the equilibrium constant expression to solve for the concentration of NO. Finally, substitute the values of O2 and N2 concentrations into the rearranged expression to find the equilibrium concentration of NO.
To find the constant in the expression (8x + 3y - 2x + 6 - 4), first simplify it. Combine like terms: (8x - 2x = 6x) and (3y) remains as is. The constant terms are (6 - 4), which equals (2). Therefore, the constant in the expression is (2).
x=y-8 z=x+12
It is 9
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
The commutative property.
Yes.Expressions are just javascript, so they can access any global variables on the page.The following works:var w = 10
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
An expression does not have an equals sign, An equation has an equals sign,
