What is the anwser to 3(x-1)-8=4(1+x)+5

Mathematics

X=20

3(x-1)-8=4(1+x)+5

1. Distribute

3x-3-8= 4+4x+5

2. Combine like terms

3x-11=4x+9

3. Add 11 or subtract 9 to both sides

3x-11+11=4x+9+11

or

3x-11-9=4x+9-9

3x=4x+20

or

3x-20=4x

If you did the first step then you subtract 4x from both sides

3x-4x=4x+20-4x

-x=20

Then you would divide by a negative 1 because there is an imagery 1 in front of the x.

-x/-1=20/-1

x=-20

If you did the second way then you would subtract 3x from both sides

3x-20-3x=4x-3x

-20=x

And you get the same answer for both ways

You can represent the measures of an angle and its complement as x° and (90 − x)°. Similarly, you can represent the measures of
pashok25 [27]

Answer:

120;60

Step-by-step explanation:

The measure of an angle is equal to twice the measure of its supplement.

This means that x = 2(180-x)

<em>Simplify</em>

x = 360 -2x

<em>Isolate the variable</em>

3x = 360

x = 120

This makes its supplement 60

The Mean will decrease while the Median and the Mode will remain with the same amount.

For Central Measures, we have Median, Mode and  Mean. They try to describe the whole distribution by one value, in the center of it.

For this question, let's pick some examples from the Old Faithful, WY Station to the National Oceanic and Atmospheric Administration from 2015, January

1st Case Scenario:

For 7 days of precipitation, (Snow, ice pellets, etc. rain) in inches:

19 19 19 24 23 23 23 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Mean = 5

Median=0 (the sum of the 15th+16th position over 2)

Mode=0 (Most common observations)

2nd Case Scenario

For 3 days of precipitation, (Snow, ice pellets, etc. rain) in inches:

0 0 0 24 0 0 23 0 19 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Mean = 2.2

Median =0

Mode=0
