Answer:
Total number of boxes = a / n boxes
Explanation:
The total number of pounds that the truck carries is "a" pounds.
This amount is distributed in several boxes, each with "n" pounds.
This means that:
Total pounds = number of boxes * number of pounds in each box
a = number of boxes * n
number of boxes = a / n boxes
Hope this helps :)

Answer:
sin 3x - cos x = 3 (sin x)(cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
Step-by-step explanation:
sin 3x - cos x
This uses Trig Identities.
sin 3x = sin (x + x + x) = sin (x+x)*cos x + cos (x + x) sin x
= 2sinxcosx * cos x + [ (cos x)(cos x) -(sin x)(sin x) ] (sin x)
sin 3x - cos x = 2sinxcosx * cos x + [ (cos x)(cos x) -(sin x)(sin x) ] (sin x) -cos x
sin 3x - cos x = 2sinxcosx * cos x + sinx (cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
sin 3x - cos x = 3 sinx cosx * cos x -(sin x)(sin x)(sin x) -cos x
sin 3x - cos x = 3 (sin x)(cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
Answer:
B (7, 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ , ] ← midpoint formula
let coordinates of B = (x, y ), then using the midpoint formula, equate to each of the coordinates of M, that is
= 2.5 ( multiply both sides by 2 )
- 2 + x = 5 ( add 2 to both sides )
x = 7
= - 1.5 ( multiply both sides by 2 )
- 7 + y = - 3 ( add 7 to both sides )
y = 4
Thus
coordinates of B = (7, 4 )
