Answer:

x = 3

Step-by-step explanation:

3(x + 2) = 6(x - 1) + 3

Divide both sides by 3.

x + 2 = 2(x - 1) + 1

Distribute the 2 on the right side.

x + 2 = 2x - 2 + 1

Combine like terms on the right side.

x + 2 = 2x - 1

Add 1 to both sides. Subtract x from both sides.

3 = x

x = 3

AB and BC are tangents to P. what is the value of x? this is really so confusing

Westkost [7]

1. Angle PAB is 90 degrees, as it is formed from the tanget to the circle at A, and the radius drawn to A.

2. AB=BC, because tangents drawn to a circle from the same point are equal.

3. PB is Common, so by the side-side-side congruence postulate, triangles ABP and CBP are congruent.

4. So measure of m(BPA)=x/2 and m(ABP)=73/2.

5. $\frac{x}{2}+90+ \frac{73}{2}=180$

$\frac{x+73}{2}=90$

$x+73=180$ , x= 107 degrees.

I'm not really good at math but I would like to help.

If each call is $.08, then the card can call last for 250 minutes.

The call lasted 202 minutes. Divide 16.16 by .08.

(-155)^4/19^2 : (155/19)^3

Snezhnost [94]

Answer:

$\frac{ { - 155}^{4} }{ {19}^{2} } \div { (\frac{155}{19} }) ^{3} = \\ \frac{ { - 155}^{4} }{{19}^{2} } \div \frac{ {155}^{3} }{ {19}^{3} } = \\ \frac{ { - 155}^{4} }{ {19}^{2} } \times \frac{ {19}^{3} }{ {155}^{3} } = \\ - 155 \times 19 = - 2945$
