If Rachel were to paint her living room alone, it would take 2 hours. Her sister Fran could do the job in 5 hours. How many hour
snow_tiger [21]

Rachel and her sister Fran together can paint the living room in \frac{10}{7} hours

Given that

Rachel can paint half of the living room in 1 hour

Fran can paint \frac{1}{5}th part of the living room in 1 hour

Let's assume together they paint the living room in x hours

⇒ together they can paint \frac{1}{x}th part of the living room in 1 hour

By proportions,

⇒\frac{1}{2}+\frac{1}{5}= \frac{1}{x} {using operation proportions and addition}

⇒\frac{7}{10}=\frac{1}{x}

⇒x=\frac{10}{7}        

⇒ together they can paint \frac{7}{10}th part of the living room in 1 hour

It means, Rachel and her sister Fran together can paint the living room in \frac{10}{7} hours

Solve for X, will mark brainliest if right
Vitek1552 [10]

Answer:

<u>x = 8</u>

Step-by-step explanation:

The sides are in proportion.

  • \frac{RG}{FG} =\frac{SH}{FH}
  • 40 / 7x + 14 = 44 / 33 + 44
  • 40 / 7x + 14 = 44/77 = 4/7
  • 40(7) = 4(7x + 14)
  • 280 = 28x + 56
  • 10 = x + 2
  • <u>x = 8</u>

Answer:

(-1, 1)

Substitute the values into the formula.

(-5 + 3/2 , 3 - 1/2)

(-2/2 , 2/2)

(-1,1)

Therefore, the midpoint is (-1, 1).
