x > 0
Step-by-step explanation:
Since there is an open circle at x = 0, then x cannot be equal to zero.
The line to the right of x = 0 is shaded meaning that x has values greater than zero.
x > 0 ← is the inequality represented on the number line
<span>a1:f9 is not an valid range because it has neither a row nor a column in common. This contrasts with a1:a3, b1:b3, and a1:a9 which each have a row in common, as well as with a1:f1, which has a column in common.
In general, to make a valid range coordinates must be specified that allow a single row or column of cells to be specified.</span>
M+B=640
M=3B
----------------------------------------------
Therefore:
3B+B=640
4B=640
B=640/4=160
----------------------------------------------
M+160=640
M=640-160=480
Therefore, Mike had sold 480 cars.
