Answer:
2500 kg/m³
Step-by-step explanation:
Density of a material is the ratio of mass and volume of that material.
The S.I unit for density is grams per centimeters cubed (g/cm³) or kilograms per meter cubed (kg/m³)
Given density as 2.5 g/cm³ , convert to kg/m³
Formula is;
1g/cm³ = 1000 kg/m³
2.5 g/cm³=? cross-multiply
=2.5×1000 = 2500 kg/m³
Answer:
Associative property
Step-by-step explanation:
<u>The given property is:</u>
A + (B + C) = (A + B) + C
which is called "associative property of addition".
Hence, this property is used in the given expression which is "rearranging the parenthesis does not affect the result."
Hope this helped!

Answer:
−4x+13
Step-by-step explanation:
collect like terms: (−3x−2x+x)+(16+5−8)
1. y = -4 - 3x
7x + 4(-4 - 3x) = -21
7x - 16 - 12x = -21
-5x = -5
x = 1
y = -4 - 3= -7
2. y = 6
-8x + 42 = -6
48 = 8x
x = 6
