1 answer:
ella [17]3 years ago
7 0

Answer:

x = 6

Step-by-step explanation:

(3x + 20)° are vertical angles with (5x + 8)° meaning that they are the same

3x + 20 = 5x + 8

20 - 8 = 5x - 3x

12 = 2x

2x/2 = 12/2

x = 6

Bezzdna [24]
1) Multiply everything by 8. It clears the fractions.
 It gives you 6n + 128 =16 - n
You add the -n to the other side of the equation.
It gives you 7n + 128= 16
You then subtract 128 from 16.
It gives you 7n= -112
You divide everything by 7

Find the distance between the points (5, -5) and (-7,4).
abruzzese [7]

Answer:

<h2>The answer is 15 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, -5) and (-7,4)

The distance between them is

d =  \sqrt{ ({5 + 7})^{2}  +  ({ - 5 - 4})^{2} }  \\  =  \sqrt{ {12}^{2}  + ( { - 9})^{2} }  \\  =  \sqrt{144 + 81}  \\  =  \sqrt{225}  \\  = 15 \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>15 units</h3>

Hope this helps you
