Answer:
x ≈ 6.8
Step-by-step explanation:
since all angles in a triangle add up to 180º:
8x-4+17x-23+3x+17=180
28x-10=180
28x=190
x ≈ 6.8
Answer:
the mean is 8 and the absolute deviation is 1.5
Step-by-step explanation:
to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!

Answer:
Step-by-step explanation:
5p + 9c = p
9c = p - 5p
9c = -4p
c = -4p/9
