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.

Find x in this porportion 5/2x =25/4

Andrei [34K]

Answer:

x = $\frac{2}{5}$

Step-by-step explanation:

Given

$\frac{5}{2x}$ = $\frac{25}{4}$ ( cross- multiply )

25 × 2x = 5 × 4

50x = 20 ( divide both sides by 50 )

x = $\frac{20}{50}$ = $\frac{2}{5}$

The midpoint of AB is M(1, 3). If the coordinates of A are(4,1), what are the coordinates of B?

Oxana [17]

Answer:

B(-2,5)

Step-by-step explanation:

$\frac{x + 4}{2} = 1 \\ 2 \times \frac{x + 4}{2} = 1 \times 2 \\ x + 4 = 2 \\ x = 2 - 4 \\ x = - 2 \\ \frac{y + 1}{2} = 3 \\ 2 \times \frac{y + 1}{2} = 3 \times 2 \\ y + 1 = 6 \\ y = 6 - 1 \\ y = 5$

Hope that this is helpful.

Have a nice day.
