Answer:
7
Step-by-step explanation:
The centroid divides the median in a 2:1 ratio. Therefore,
AD = 2DM
x + 3 = 2(2x - 1) Remove parentheses
x + 3 = 4x – 2 Add 2 to each side
x + 5 = 4x Subtract x from each side
3x = 5 Divide each side by 3
x = ⁵/₃
AM = AD + DM
= (x + 3) + (2x – 1)
= 3x + 2 Substitute the value of x
= 3 × ⁵/₃ + 2
= 5 + 2
= 7
Length of median AM = 7.
Answer:
i think for the first one i think it would be 250mm
and the second one would probably i think 1500
Step-by-step explanation:
Answer:
PO = 20
Step-by-step explanation:
They are equidistant from the centre
PG = GO
x-4=1/2x+3
Multiplying both sides by 2
2(x-4)=x+6
2x-8=x+6
2x-x = 6+8
x = 14
Now
PO = 14-4+7+3
PO = 10+10
PO = 20
Answer:
The answer is C. x = 5
Step-by-step explanation:
Plug in 5 and mutiply it by 4 and get 20, 20 plus 1 is 21.
Answer:
(4.5,-6)
Step-by-step explanation:
6x = 27
x = 27/6=4.5
9-3y = 27
-3y = 18
y = -6
