X = 7 !! you would just use inverse operations.
Answer:
{x:x>6}
Step-by-step explanation:
x-3>3
Add 3 to each side
x-3+3>3+3
x>6
{x:x>6}
Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters
2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L
7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.
answer: From this information the Iron density is 7.92 Kg/L or 7.92 g/cm³.
Answer:
2(4x−1)(4x−1)
Step-by-step explanation:
first you find the GCF of all of the terms, which is 2 because 32, 16, and 2 are all divisible by 2. Then you are left with 2(16n^2-8n+1). Now you factor the rest of it and you are left with 2(4x−1)(4x−1)
Note, if you have a linear scale, then the surface will be the square othis scale & the volume will be the cube of the linear.
Our linear scale is 3/7. then the ration of their corresponding bvolume is:
3³/7³ = 27/343
