The answer is y=16
You must first combine like terms (8y-3y = 5y)
Then you must subtract 7 on both sides to cancel out the 7
You are left with 5y=80
Divide 5 by both sides to get you answer 80/5 = 16 so y=16

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.
