mean = sum/n
mean = (5 + 7 + 7 + 9 + 12 + 16 + 21)/7
mean = 77/7
mean = 11
the 2 angles are congruent so...
x+40=3x set the 2 equations equal to each other
40=2x subtract x from both sides
20=x divide by 2
x=20 is the final answer
Have a blessed day!

so the both cancel out each other
so it will just be 11.9 ,since it is -1
Hi!
The answer is :
32.15 = (3 x 10) + (2 x 1) + (1/10) + (5/100)
That's 32.15 in expanded fraction.
Hope it helps and have a wonderful day!
