Weather can be simply measured by observing and recording, which of the following? a. Temperature b. Rainfall c. Cloudiness d. Humidity e. Wind f. Sunshine

Although all of these can be used, humidity is one I have heard the most. Temperature is a runner up, and then wind. Weather isn’t scientifically measured by rainfall or cloudiness. It is also not typically measured by sunshine.

Amath expression is a collection of one or more terms, which are separated by the signs ( + , - , x , / ).example :   8+b8+b  or  a−3a−3in algebra, an equation is a mathematical statement with two expressions where, each expression is separated by an equal (=) sign. variables can be present on both the sides of the equality (=) sign and we use letters to denote such variables.example 1:   x=4+2x=4+2  , [here, we can observe that the variable is present only on one side of the equation].example 2:   2x+3=x+42x+3=x+4  , [here, we can observe that the variables are present on both side of the equation].
