The answer to your math question is x=5
As you know, 4.78 is less than 5, so
.. yes, x=4.78 is a solution to x < 5
As you know, 6 = 6, but is not less than 6.
.. no, x=6 is not a solution to x < 6.
Answer:
PQ = 3.2
Step-by-step explanation:
You must use the addition property of equality, and subtract 16 from the of the 5x, and add it to the other side.
After that, you have 5x = 16
You then divide both sides by 5.
5x/5 = 1x = x
16/5 = 3.2
x = 3.2
Therefore, the side 'PQ' is equal to 3.2

Large sphere's radius = R,
small sphere's radius = r, R = 8r
surface area of a sphere (SA) = 4×pi×radius^2
So what we need is the SA of the larger in terms of the smaller sphere, so if:
SA (of R) = 4×pi×R^2, then plug in "8r" for "R"...
SA = 4×pi×(8r)^2 = 4×3.14×64r^2
SA = 12.57×64r^2 = 804 r^2
Therefore the SA of the larger sphere is 804 times the SA of the smaller sphere.
I hope that makes sense!
