A graduated cylinder containing 40 mL of water has a total mass of 60 g. A solid object carefully lowered into the graduated cylinder. The level of the water rises to 70 mL. The total mass of the cylinder, water and object is now 95 g. What is the mass, volume and density of the object?
Please help.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
