I think it's 240cm³, ok? Let's go.

d = \dfrac{m}{V}
\\\\\\
d = \dfrac{2160g}{240cm^{3}}
\\\\\\
\boxed{d = 9g/cm^{3}}

Find the equation of the line parallel to the line y = 2x + 3 and expect oy in (0; 1)
nignag [31]

Step-by-step explanation:

Any lines that are parallel to each other have the same slope (coefficient of x is the same)

In this case, y = 2x + c.

Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.

Hence, the equation of the parallel line is y = 2x + 1.

Mickey used these calculations to find how much he would spend on 7 cartons of eggs, if 12 cartons of eggs cost $22.20. Describe
timofeeve [1]
Mickey incorrectly calculated the unit price:
\frac{12}{22.20} = 0.54

The correct operation is:
\frac{22.20}{12} = 1.85

Each carton costs 1.85, so 7 cartons cost
1.85 \times 7 = 12.95

An angle bisector is a line or ray that divides an angle into two congruent angles
so
in this problem
m∠RST=m∠RSV+m∠VST
m∠RSV=m∠VST
hence
m∠RST=2*m∠RSV --------> equation 1
we have
m∠RST=(6x-24)
m∠RSV=(2x+8)
Substitute in the equation 1
6x-24=2*(2x+8)
6x-24=4x+16
6x-4x=16+24
2x=40
x=40/2
x=20 degrees
therefore
the value of x is 20 degrees
