Answer:

51ft, 17ft, 39ft

Step-by-step explanation:

longest = x

2nd = $\frac{1}{3}$ x

3rd = x - 12

P = 107

a + b + c = Perimeter

x + $\frac{1}{3}$ x + x - 12 = 107

$\frac{7}{3}$ x -12 = 107

$\frac{7}{3}$ x = 119

x = 51

$\frac{1}{3}$ x = 17

x - 12 = 39

Suppose 15% of x equals 20% of y. What percentage of x is y ?

WINSTONCH [101]

Answer:

x = $133\frac{1}{3}$ of y

Step-by-step explanation:

Given:

15% of x equals 20% of y

So,

0.15x = 0.20y

x = 0.20 y / 0.15

x = 1.3333y

x = $133\frac{1}{3}$ of y

A line’s equation is given in point-slope form:<br> y−6=(−23)(x+6)<br> This line’s slope is?

Nikolay [14]

The slope of the line is -23

<h3>How to determine the slope of the line?</h3>

The line’s equation is given in point-slope form:

y − 6 = (−23)(x + 6)

The line’s equation in point-slope is represented as:

y − y1 = m(x - x1)

Where

m represents the slope

By comparing y − y1 = m(x - x1) and y − 6 = (−23)(x + 6), we have

m = -23

Hence. the slope of the line is -23
