38- (-30) which is the same as 38 plus 30 which is 68. If you wonder why you add, comment below
= (3/4 + 1/3)/(1/6 + 3/4)
= (3/4 + 1/3)/(1/6 + 3/4)
Multiply numerator and denoiminator by 12
=12(3/4+1/3) / 12(1/6 + 3/4)
= (3*3 + 1*4) / (2 + 3*3)
= 13/11
Step-by-step explanation:
<em>NOTE: Bolded letters are vectors</em>
Given that ,
From vector triple product rule,
If these both are equal, then :
⇒b(a.c)-c(a.b) = b(a.c)-a(b.c)
⇒(-a.b)c = (-b.c)a
⇒(|a||b|sin∅)c = (|b||c|sinФ)a (cancel |b| on both sides)
A , C are the unit vectors of a and c respectively .
Two vectors can be equal on when their magnitude and directions are same.
That is when ,
⇒(|a||c|sin∅)A = (|a||c|sinФ)C
⇒sin∅A = sinФC
This can only be possible when the vectors are collinear because the angle made by the vectors with the vector B should be the same or supplementary and the vectors A and C must be in the same direction.
Answer:
-7x
Step-by-step explanation:
2x + 3x - 12x
Add 2x + 3x, resulting in 5x
5x - 12x = -7x
It's negative because the -12 is the bigger number.
Hope this helps :D
