(y-y0)/(x-x0)=slope
so (85-76)/(2-(-11))=9/13

2x = 15 - 3x -- add 3x to both sides

5x = 15 -- divide both sides by 5

x = 3 -- simplest form

If one-sixth of a number plus one-third returns two-thirds of that number What is the number

Solnce55 [7]

Answer:

$x= \frac{2}{3}$

Step-by-step explanation:

Let the number be x

Given

$\frac{1}{6}x + \frac{1}{3} = \frac{2}{3}x$

Required

Find x

$\frac{1}{6}x + \frac{1}{3} = \frac{2}{3}x$

Collect Like Terms

$\frac{1}{6}x - \frac{2}{3}x = - \frac{1}{3}$

Take LCM

$\frac{1 - 4}{6}x = \frac{-1}{3}$

$\frac{- 3}{6}x = \frac{-1}{3}$

Multiply both sides by 6

$6 * \frac{- 3}{6}x = \frac{-1}{3} * 6$

$-3x= -2$

Divide both sides by -3

$\frac{-3x}{-3}= \frac{-2}{-3}$

$x= \frac{2}{3}$

Hence, the number is $\frac{2}{3}$

Answer:

2:5, 5:2

Step-by-step explanation:

Lets use 30 and 12. 12 divided by 30 is 0.4, which reduced is 2:5, or u can write 0.4. Thats oil to flour

But opposite numbers for flour to oil, bc of common sense.

Hope this helps(would be appreciated if you mark this answer brainliest bc need for lvl up. )

pogonyaev

You have coordinates of tree T(16,21) and of rock R(3,2). Let S be a point that denotes treasure. Since treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio, you can state that

$\dfrac{\overrightarrow{RS}}{\overrightarrow{ST}}=\dfrac{5}{9}.$

Find the coordinates of these vectors:

$\overrightarrow{RS}=(x_S-3,y_S-2), \\
\overrightarrow{ST}=(16-x_S,21-y_S).$

Then

$\dfrac{x_S-3}{16-x_S} =\dfrac{5}{9}$ and $\dfrac{y_S-2}{21-y_S} =\dfrac{5}{9}.$

Solve these two equations:

$9(x_S-3)=5(16-x_S),\\ 9x_S-27=80-5x_S,\\ 9x_S+5x_S=80+27,\\14x_S=107,\\ \\x_S=\dfrac{107}{14}\approx 7.6.$

$9(y_S-2)=5(21-y_S),\\9y_S-18=105-5y_S,\\9y_S+5y_S=105+18,\\14y_S=123,\\ \\y_S=\dfrac{123}{14}\approx 8.8.$

Answer: the treasure are placed at point (7.6,8.8), so the correct choice is B.
