Answer:

(-1, 9)

Step-by-step explanation:

given

$y = - 3x + 6 \\ and \\ y = 9 \\ then \: we \: need \: to :\ find \: x \: so \: that \: when \: plugged \\ to \: - 3x + 6 \: the \: result \: is \: 9 \\ by \: transitive \: rule \\ y = 9 = - 3x + 6 \\ 9 = - 3x + 6 \: (substract \: both \: sides \: with \: 6) \\ 3 = - 3x \: (divides \: both \: sides \: with \: - 3) \\ - 1 = x$

If the surface area of a cube is 150 cm2, what is the volume of the cube

Fiesta28 [93]

Answer:

V = 125 in^3

Step-by-step explanation:

A cube has 6 sides, and the area of each is equal to the side length squared:

A = 6x^2

A is given as 150 cm^2, and so is equal to 6x^2. Thus, x = the side length = 5 cm.

The volume of the same cube is given by V = x^3, which here is 5^3 in^3, or V = 125 in^3

I need help please. It will really help me

Answer:

x = 15

∠AOB = 15°

∠BOC = 165°

Step-by-step explanation:

Angles on a straight line add up to 180°

$\sf \implies \angle AOB + \angle BOC=180$

Substitute the given expressions for the angles:

$\sf \implies (2x - 15) + 11x = 180$

Collect and combine like terms:

$\sf \implies 2x +11x- 15=180$

$\sf \implies 13x- 15=180$

Add 15 to both sides:

$\sf \implies 13x- 15+15=180+15$

$\sf \implies 13x=195$

Divide both sides by 13:

$\sf \implies \dfrac{13x}{13}=\dfrac{195}{13}$

$\sf \implies x=15$

Now substitute the found value of x into the expressions for each angle:

$\sf \implies \angle AOB =2(15)-15=15^{\circ}$

$\sf \implies \angle BOC =11(15)=165^{\circ}$
