Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.
<h3>What is simplification?</h3>Simplification is to make something easier to do or understand and to make something less complicated.
Given
Carmen simplifies the expression .
We can add x term with x, y term with y, and constant with constant.
On simplifying, we have
Thus, the coefficeint of y is 10.

Answer:
8.900 g/cm³
Step-by-step explanation:
The density of an object is given by:
ρ =
ρ is the density.
M is the object's mass.
V is the object's volume.
Given values:
M = 222.50 g
V = 25.00 cm³
Substitute the given values into the equation and solve for ρ:
ρ = 222.50/25.00
ρ = 8.900 g/cm³
