Both climbers rested on the wall at a constant height for 2 minutes.

<h3>How to determine the true statement?</h3>

The illustrative graph that represents the climbers' movement is added as an attachment

From the attached graph, we have the following observation

The line of Abby's movement is horizontal from x = 4 to x = 6
The line of Brynn's movement is horizontal from x = 5 to x = 7

The difference between the endpoints of both horizontal line is

Difference = 6- 4 = 2

Difference = 7 - 5 = 2

This means that both Brynn and Abby stopped for 2 minutes

Hence, the true statement about is that (d) Both climbers rested on the wall at a constant height for 2 minutes.

katrin [286]

Since there are 6 possible results when rolling a die, each number has a 1 in 6 chance that it will be rolled.
1 and 2 are two possible results, so there is a 2 in 6 chance they will be rolled. As a fraction:
2/6
simplified:
1/3

Let's go:

$\frac{y}{3} = \frac{27}{y} \\\\ y^2 = 27.3 \\\ y^2 = 81 \\\ y = \sqrt{81} \\\ y = 9$

I hope I helped you.

Circles M and K are congruent, QR is congrent to LN. Find the length of QR

Novosadov [1.4K]

Given QR is congrent to LN and QR = 4x + 2 and LN = x + 7.

So, QR = LN

Hence, we can set up an equation as following:

4x + 2 = x + 7

4x + 2 - x = x + 7 - x Subtract x from each sides.

3x + 2 = 7 By simplifying.

3x + 2 - 2 = 7 - 2 Subtract 2 from each sides.

3x = 5

$\frac{3x}{3} =\frac{5}{3}$ Divide each sides by 3 to isolate x.

So, $x=\frac{5}{3}$

Next step is to plug in $x=\frac{5}{3}$ in QR = 4x+2 to get length of QR.

So, $QR = 4(\frac{5}{3})+2$

$=(\frac{20}{3})+\frac{2}{1}$ Since 2 can be written as 2/1.

By multiplying the second fraction by the common denominator 3.

$=(\frac{20}{3})+\frac{2*3}{1*3}$

$=(\frac{20}{3})+\frac{6}{3}$ By simplifying the second fraction.

$=(\frac{26}{3})$

So, $QR=\frac{26}{3}$
