Fist, write the equation as you see it:

7x + 12 = 9x

Next you have to put all the x’s on one side, whenever you move a number from one side to another it changes its sign (if it’s + it becomes - and if it’s - it becomes +)

7x - 9x = -12

Next add the x’s together:

-2x = -12

Then you must divide the two negive number which leave you with:

x = 6

The answer is x = 6.

Hope this helps!:)

The line plot and the bar graph show the same test scores. Where should you look to find the greatest common test score?
Klio2033 [76]

Answer:

The tallest column of the line plot

Step-by-step explanation:

A line plot shows the frequency of data, in short it shows how many times something has occurred or the number of times data occurs in a group of data.

The number of data is represented by markers or in this case "x"s. The more x's along the column, the more times it occurred.

The bar graph there does not show the frequency of the different scores. This shows the relationship between the test number and the percentage of the scores obtained. It does not tell you the individual scores obtained.
