Well to start, we need to combine like terms all the equations together , so
n+ 4n+4n = 9n
-2-7 = -9
put them together and it’s
9n - 9
the perimeter is 45 so
9n - 9 = 45
+9 +9
——————
9n = 54
——————-
9 9
Then the 9 cancels, drop down the n and divide 54/9 and you get

n = 6

and that’s the answer
to prove it
you can do
4(6) - 2 = 22
4(6) - 7 = 17
+ 6 because you just replace the n with 6
Add them...
22+17+6 = 45
and so now we know for sure the value of n is 6!

1.) What is the mode of the data ? Show work ( A.3, B.5, C.8, D.10 )
ArbitrLikvidat [17]
Hey there.

1.) The mode is the number that's most frequent in a given list.
In our list, we have 2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10.
Our most frequent number is 6; therefore, our mode is 6.

2.) The median is the number in the middle of a list organized from least to greatest.
2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10;
4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9;
4, 5, 5, 5, 6, 6, 6, 6, 7;
5, 5, 5, 6, 6, 6, 6;
5, 5, 6, 6, 6;
5, 6, 6;
6.
6 is our median.

I hope this helps, despite your answer choices not providing the correct answer.

An equilateral triangle is a triangle that has three sides of the same length. the perimeter of an equilateral triangle is 48.6
aleksklad [387]
We know that a triangle has three sides, all the same length (its equilateral, after all)

The equation to find the length of each side is

Perimeter divided by 3

or in this case

48.6 divided by 3=16.2cm (don't forget the unit)

Hope that helps :)
