First if x equals 1 then you would do 3x1 which would get you 3, then add the 3 plus 3 to get 6
Expand and collect like terms:
10x > 5(x-4)
10x > 5x-20
5x > -20
x > -4, so the answer is B
Answer:
4x6=24
Step-by-step explanation:
Answer:
the density of copper is 90.03g/cm³
Step-by-step explanation:
This problem bothers on the density of a substance, this case for a copper material
Given data
Mass of copper m = 1355g
Volume of copper block v= l*b*h
10*5*3=150cm³
We know that the density
ρ= mass/volume
ρ= 1355/150
ρ= 90.03g/cm²
The density of a substance is defined as the mass of the substance per unit volume
The distance in scientific notation is 5.6x10^5 miles. ^ is to the power of. Start from the right of a number and count the number of spaces till you get between the first two numbers, and that is how you get your exponent. It would be a different case if you had a decimal number though. For example the scientific notation of 0.00000256 would be 2.5x10^-6. You would count the number of spaces from the left to right and the exponent would be a negative.
