Given mass=1 kg, volume=400cm³, density=?
The formula for finding density is ρ=m/v where ρ is density, m is volume and vis volume
ρ=1kg/400cm³
ρ=0.0025kg/cm³
Therefore the density of the sand is 0.0025kg/cm³
(4+8x)-(-2+7x) = 4+2+8x-7x

Answer:
(2,6)
Step-by-step explanation:
Substitute y=3x into y=x+4 to get 3x=x+4. Solve for x.
x=2
Put x into either equation to get y=3(2) or y=(2)+4
y=6
Slopes of perpendicular lines are NEGATIVE RECIPROCAL to each other
namely, if say one has a slope of a/b then the other will have a slope of
what the dickens does that mean?
well, it means that their product is
so... in this case, one has a slope of 3/4 and the other has a slope of d/2
thus
