Answer:
9:12 is bigger
Step-by-step explanation:
You need to make the fraction denominator equal
(6:9)
6*12=72
9*12=108
72/108
(9:12)
9*9=81
12*9=108
81/108
81 is bigger than 72
Answer: Median
You can't use the mode in here, since there are no repeated numbers. But You can use mean and median. If you use the mean, you will get 57. If you use the median, you will get 75.5. This means that the median will give you the best grade.
Explanation:
Mode: The most repeated number.
Median: The Middle number of statistics.
Mean: The average of all numbers.
your answer will be the last one
Answer:
x = -9
Step-by-step explanation:
12 + 2x + 24 = 27 + x
(12 + 24) + 2x = 27 + x
36 + 2x = 27 + x
subtract 27 from both sides
36-27 + 2x = 27-27 + x
9 + 2x = x
subtract x from both sides
9 + x = 0
subtract 9 from both sides
x = -9
(the steps could've been faster but that shows the most work)
check:
12 + 2(-9) + 24 = 27 + (-9)
36 - 18 = 18
18 = 18
True!
so -9 is correct
What does the shape look like?
Ok, so say you are calculating the surface area of the shape in the image below.
You would calculate the area of both shapes (the vertical box and the horizontal one), then subtract the area of the left face of the left rectangle (it is 10x20). That way, you are subtracting the area from the tall box. Make sure when you calculate the area of the short box that you don't include the left face (which is non-existent because it is attached to the tall box). If this is still really confusing (don't blame you if it is!!), let me know and I will walk through and example with you. Hope this helps!!
