Answer:

x = 17/6

Step-by-step explanation:

First of all remove parenthesis by using distribution

6x + 9 - 12x + 24 = 16

Then collect all like terms

-6x + 33 = 16

After that move the constant to the right

- 6x = 16 - 33

Calculate 16 - 33

-6x = -17

Divide both sides

x = 17/6

Hope this helps!

24h out of 36  24/36 GCF is 12 divide to and bottom by 12
24 / 12 is 2   36 / 12 is 3  2/3    Shane worked for 2/3 of 36h
Percentage: 100% / 3 (because there is 3 parts)= 33.333333333333 
33.33333333333 x 2 (because it is there is 2 parts needed) = 66.6666666666%
Shane has worked for 66.6666666666% of 36 hours
 
 Andrew:
 4 x 6 = 24

What two whole numbers is 29−−√ between?: 3 and 4 4 and 5 5 and 6 6 and 7
jolli1 [7]

The two whole numbers are 5 and 6 ⇒ 3rd answer

Step-by-step explanation:

To prove that a square root number lies between which two consecutive integers do that

  • Find a square number less than the number under the root
  • Find a square number greater than the number under the root
  • Find the square root of the square numbers, they will be the two integers that the root lies between them

∵ The number is \sqrt{29}

- Find a square number less than 29

∵ 25 is a square number

∵ 25 is less than 29

- Find a square number greater than 29

∵ 36 is a square number

∵ 36 is greater than 29

∴ 25 < 29 < 36

- Take √ for each number

∴ \sqrt{25} < \sqrt{29} < \sqrt{36}

∵ \sqrt{25}  = 5

∵ \sqrt{36}  = 6

∴ 5 <  \sqrt{29}  < 6

The two whole numbers are 5 and 6
