$x {}^{2} - x - \frac{5}{2} = 0$
(1±√(1-4(1)(-5/2))/(2)

(1±√1+10)/(2)

$\frac{1 + \sqrt{11} }{2} \\ \frac{1 - \sqrt{11} }{2}$

Person A can paint the neighbor's house 5 times as fast as Person B. The year A and B worked together, it

LenKa [72]

Answer:

Person A paints the house in 12 days.

person B paints the house in 60 days.

Step-by-step explanation:

The together rate is the sum of each separate rate.

Person A can paint the neighbor's house 5 times as fast as Person B.

This means that the rate of person A is 1/x, and the rate of person B is 1/5x.

The year A and B worked together, it took them 10 days.

This means that:

$\frac{1}{x} + \frac{1}{5x} = \frac{1}{10}$

Multiplying everything by 10x

$10 + 2 = x$

$x = 12$

This means that:

Person A paints the house in 12 days.

person B paints the house in 60 days.

The figure shows two intersecting lines and the measures of the resulting angles. Write an equation to help you solve for x. The

Svetlanka [38]

Given:

The given figure shows the intersection of the two lines.

The angles formed by the intersection of the two lines are (3x - 8)° and (2x + 12)°

We need to determine the equation to solve for x and to find the value of x.

Equation to solve for x:

Since, the two angles (3x - 8)° and (2x + 12)° are vertically opposite angles and the vertical angles are always equal.

Hence, we have;

$3x-8=2x+12$

Thus, the equation to solve for x is $3x-8=2x+12$

Value of x:

The value of x can be determined by solving the equation $3x-8=2x+12$

Thus, we have;

$x-8=12$

$x=20$

Thus, the value of x is 20.

Which of the following infinite series has a finite sum? Explain your reasoning.

ikadub [295]

Answer:

d. 20+10+5+2.5+...

Step-by-step explanation:

No geometric series with a common ratio of magnitude greater than 1 will have a finite sum. Nor will any arithmetic series.

Those descriptions exclude answer choices a, b, c. Choice d is a geometric series with a common ratio of 1/2, so will have a finite sum. (It is 40.)

What is the distance between R(–3, 1) and S(4, 5)? Round to the nearest tenth.

Fed [463]

The answer is (-7,4)

$\binom{ - 3}{1} - \binom{4}{5} = \binom{ - 7}{4}$

good luck
