Answer:
1.2n=0.45n+1.5
Step-by-step explanation:
2.8 lbs
Explanation- 16-6.8=9.2
12-9.2=2.8
8/9 because there are 36 inches in a yard and you need to convert all the yards to inches and turn it into a fraction. The original fraction is 192/216 but it simplifies to 8/9.
Density

is given by

where m is the mass of the object
V is the Volume of the object
let m1 be the mass of the smaller cube
let m2 be the mass of the larger cube
you know that the larger cube has twice the mass of the smaller cube
or m2=2*m1
so apply this information into the density equation and you can determine the volume of the larger cube
Step-by-step explanation:
3x+8=5x+4( congruent side of ∆Abc and qrp
8-4=5x- 3x
4= 2x
4/2=x
2= x
now, replace value of Ab
3x+8
3*2+8
6+8
14
length of ab =14
