8(-9-5x)
=8(-9) - 8(5x)
= -72 - 40x
= - 40x - 72

expand by using distributive property

hope it helps

Answer:

B) 8x - 20 + 2x = 11

Step-by-step explanation:

4(2x - 5) + 2x = 11

use pemdas

parenthesis comes first

open the parenthesis

4 * 2x - 4 * 5 + 2x = 11

8x - 20 + 2x = 11

Complete Question

Answer:

The arc PR is $\theta _{PR} = 84$

Step-by-step explanation:

A descriptive diagram of the diagram given in the question is shown on the first uploaded image

In the circle tangent $\= {M \= Q}$ , secant $PE$ and chord $PF$ are drawn

given that $\theta _ {MPQ} = 102^o$ , $\theta _{M} = 60^o$

The objective is to determine PR

From the diagram we see that MQ is a straight which implies that the the angle

$\theta_{NPM} = 180 -102$

$\theta_{NPM} = 78^o$

Now looking at triangle NMP we see that

$\theta _{MNP} = 180 -[ \theta_{NMP} + \theta _{NPM}]$

$\theta _{MNP} = 180 - [60 + 78 ]$

$\theta _{MNP} = 42 ^o$

Now the measure of an inscribed angle is half the measure of its arc intercepted, this statement is the inscribed angle theorem

So with the knowledge

Then

$\theta_{RNP} = \frac{1}{2} \theta_{PR}$

Looking at the diagram we see that

$\theta _{MNP} = \theta_{RNP} = 42 ^o$

$42 = \frac{1}{2} \theta _{PR}$

$\theta _{PR} = 2 * 42$

$\theta _{PR} = 84$

Six people are standing in line for concert tickets. Their average age is 27. the average age of the first four people in line i

Vanyuwa [196]

Total age
6 * 27 
162 

Subtotal age of first 4 
4 * 23 
92 

Subtotal of last 3 
3 * 34 
102 

In the total of the first 4 and last 3 
the 4th person has been counted twice. 
This second time must be subtracted. 

Therefor 
92 + 102 - x = 162 
194 - x = 162 

Subtract 194 from both sides 
-x = -32 

Multiply both sides by -1 
x = 32
