3 0

Answer:

x = 2

Step-by-step explanation:

1 - Rewrite

6 - 2/3 (x+5) = 4x

2 - Distribute

6 - 2/3x + 10/3 = 4x

3 - Combine like terms and get x alone

6 10/3 - 2/3x = 4x

           +2/3x  +2/3x

          6 10/3 = 4 2/3x

------------------------------- Convert to decimals

6.3333333333.... = 4.333...x

-------------------------------- Divide both sides by 4.33...x

2 = x

Hope this helps :)

What shape is your field of vision?
Nat2105 [25]

The shape of my field is an <u>oval</u>

It's<u> oval</u> rather than round because I have two eyes, and each has a separate field like the one pictured here. Putting them together creates an oval. So if you wanted to represent what I can see, you would take a wide-angle photo from my vantage point and cut out a roughly oval shape

Therefore, the shape of my field is an <u>oval</u>

Need help if anything can show me how to do it in steps !
Elanso [62]

Answer:

x=59/5 or x=11.8 depends on which one you want to do both are true

Step-by-step explanation:

Start with what you are given

angle 4= 5x+6 and angle 3=65 because lines m and n are both parallel angle4=angle3 in other words 5x+6=65

what you want to do is get x by itself.

1. Subtract 6 from both sides

5x+6-6=65-6

5x=59

2. Divide both sides by 5

5x/5=59/5

x=59/5

3. Check to see if you can simplify the fraction and if you teacher wants it in decimals or exact fraction.

x=59/5 or x=11.8 they are the same just ones a decimal the other is left as a fraction
