A rhinoceros weight when rounded to the nearest thousand was 4,000 pounds. Which of these is the least the rhinoceros could have
Rudik [331]

Answer:

B- 3,500.

Step-by-step explanation:

This is because 3,500 is the lowest number that can be rounded to 4,000.

3,999 and 4,001 can also be rounded but.. (let me show you an image to help).

3,500 < 3,999 < 4,001.

That goes from smallest to largest numbers that round to 4,000.

Hope that helps. x

Solve the equation for x 2/3x-1/9x + 5 = 20
Nady [450]

\bold{Answer}

\boxed{\bold{X \ = \ 27}}

\bold{Explanation}

  • \bold{Solve: \ \frac{2}{3}x-\frac{1}{9}x+5=20}

\bold{--------------------------}

  • \bold{Subtract \ 5 \ From \ Both \ Sides}

\bold{\frac{2}{3}x-\frac{1}{9}x+5-5=20-5}

  • \bold{Simplify}

\bold{\frac{2}{3}x-\frac{1}{9}x=15}

  • \bold{Multiply \ By \ LCM: \ LCM \ = \ 9}

\bold{\frac{2}{3}x\cdot \:9-\frac{1}{9}x\cdot \:9=15\cdot \:9}

  • \bold{Simplify}

\bold{6x-x=135}

\bold{5x=135}

  • \bold{Divide \ Both \ Sides \ By \ 5}

\bold{\frac{5x}{5}=\frac{135}{5}}

  • \bold{Simplify}

\bold{X \ = \ 27}

\boxed{\bold{Eclipsed}}
