3(3x - 8) + 4x = -2(12 - 7x) - x

9x - 24 + 4x = -24 + 14x - x    <em>distributed 3 on the left and -2 on the right</em>

   - 24 + 13x = -24 + 13x        <em>added like terms on the left and the right</em>

<u>             -13x</u>     <u>        -13x </u>

   -24          =   -24

           TRUE

A true statement means infinitely many solutions (aka All Real Numbers)

Answer:

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > \sqrt{300}, 300%

Step-by-step explanation:

Given numbers are,

2.38 × 10², √300, 2⁸, 300%, 6³, 2.16 × 10¹

We have to arrange these numbers in the decreasing order(from greatest to least)

2.38 × 10² = 2.38 × 100 = 238

√300 = 10√3 ≈ 17.32

2⁸ = 256

300% = \frac{300}{100} = 3

6³ = 216

2.16 × 10¹ = 21.6

Therefore, decreasing order (from the greatest to least) will be,

256 > 238 > 216 > 21.6 > 17.32 > 3

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > \sqrt{300}, 300%

write an equation in standard form with integer coefficients for the line with slope 6/11 going through the point (-1,-6)
yKpoI14uk [10]
If the slope is 6/11 then, in y=mx+b form, m will be 6/11.  When you multiply 6/11 and -1 you get -6/11.  To get the y (-6), you have to add -60/11.  So in, y=mx+b form the equation is y=6/11x+(-60/11).  To make it standard form, you add negative 6/11x to both sides and then multiply by 11 to get rid of the fractions. So therefore the equation would be:

-6x + 11y = - 60
