First, distribute the -3(-2x + 1).
-3 x -2x = 6x -3 x 1 = -3 -3(-2x + 1) = 6x - 3
Now we have:
9 - 5 1/2x + 6x - 3
Combine like terms.
-5 1/2x + 6x = 1/2x 9 - 3 = 6
The two terms we are left with are 1/2x and 6.
The simplified version of this expression is 1/2x + 6.
Hope this helps!
I just answered a so let's start with b :
______________________________
b. The equivalent resistance of series
resistances is equal to their sum
Thus :
equivalent resistance = 480 + 360
equivalent resistance = 840
_______________________________
c.
I = V ÷ R
I = 120 ÷ 840
I = 0.1428 A
_______________________________
d. 0.1428 A
_______________________________
e. 480 ===》 120 - ( 480 × 0.1428 ) =
120 - 68.544 =
51.456
360 ===》 120 - ( 360 × 0.1428 ) =
120 - 51.408 =
68.592
