Answer: Honestly middle school grades, especially electives don't matter much. don't worry about it.
Use elimination.
-x = -6
X = 6
-4 (6) + 4y = 12
Y = 9
(X,y)
(6,9) is the solution
The mean is 10,724.28.
Explanation:
The mean is all of the values divided by the number of values there are.
So what you have to do is add all of the numbers and divide it by the amount of numbers there are.
10,150+10,211+10,424+10,769+10,884+11,155+11,477= 75,070.
Since there are 7 numbers, divide 75,070/7 and you get your mean, which is 10,724.28 rounded.
Answer: I can only see the big boxes so will answer them
5/6 - 1/3
Multiply the two denominators together get 18
Then multiply the bottom denominator with the opposite numerator
The sum has now changed to:
15/18 - 6/18
15 - 6 = 9
9/18 can then be simplified to 1/2
Answer:
-(10/7)
Step-by-step explanation:
See attached graphic. The slope of the Green Line is cut off in the problem photo, but can be calculated from the graph to find the slope of the Red Line. The answer options are on drugs; pick the one that looks closest.
