You divide 820 by 42 and the answer comes out to be 344.4 it has a decimal because it doesn't divide equally
Answer:





Step-by-step explanation:
The figure has been attached, to complement the question.



Given that J is the centroid, it means that J divides sides CD, DE and CE into two equal parts respectively and as such the following relationship exist:



Solving (a): DG
If
, then



Make DG the subject

Substitute 52 for DE


Solving (b): GE
If
, then


Solving (c): DF

So:

Solving (d): CH


Solving (e): CE
If
, then



You can use elimination
7x - 3y = 4
-10x + 3y = 2
Add both equations
-3x = 6, x = -2
Plug in -2 for x in one equation
7(-2) - 3y = 4
-14 - 3y = 4
-3y = 18, y = -6
Solution: x = -2, y = -6
Okay to start off the problem you make a fraction of 360/3. you then divide 360 by 3. 360÷3=120. so the rate and unit rate is 120 customers
