28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6
I would believe it to be 22
Answer:
5190 g
Step-by-step explanation:
Calculate the volume:
28.0 cm × 4.90 cm × 3.60 cm = 493.92 cm³
Density is mass divided by volume:
D = M / V
Solving for mass:
M = D V
Substituting values:
M = (10.50 g/cm³) (493.92 cm³)
M = 5186.16 g
Rounding to three significant figures, the mass is 5190 g.
The volume of a rectangular prism can be given by the form
![V= b*h*w](https://tex.z-dn.net/?f=V%3D%20b%2Ah%2Aw)
you know Volume, base, and height but you dont know width
so divide b and h to both sides
![\frac{V}{b*h} = w](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7Bb%2Ah%7D%20%3D%20w)
and you cna solve for width
now for 6.
dividing by a number is the same as multiplying by its reciprocal
