Is 1/8 grader than or less than 2/5
Oduvanchick [21]

\large\text{Hey there!}

\mathsf{Is\ \dfrac{1}{8}\ greater\ than\ or\ less\ than\ \dfrac{2}{5}\ ?}

\large\text{Personally, if you convert your fractions into decimals it can be easier to}\\\large\text{to answer your question. Or you could even match it with the LCD}\\\large\text{if it is easier for you!}

\mathsf{\dfrac{1}{8}=0.125} \\\\\mathsf{\dfrac{2}{5}=0.40}

\large\text{The\ LCD (Lowest Common Denominator) is 40}

\mathsf{Match\ your\ fractions\ with\ your\ LCD}\\\\\boxed{\mathsf{\dfrac{1}{8}}}\boxed{\mathsf{\dfrac{2}{5}}}\\\boxed{\mathsf{\dfrac{5}{40}}}\boxed{\mathsf{\dfrac{16}{40}}}

\large\text{We compared }\mathsf{\dfrac{1}{8}\ \&\  \dfrac{5}{40}.}\large\text{ We also compared }\mathsf{\dfrac{2}{5} \  \& \ \dfrac{16}{40}}

\mathsf{Both\ \dfrac{2}{5} \& \ \dfrac{16}{40}\ are\ LESS/ SMALLER\ than\ \dfrac{1}{8} \ & \ \dfrac{5}{40}}

\boxed{\boxed{\large\text{Thus your answer is: \boxed{\mathsf{\dfrac{1}{8} \ is\ GREATER\ than\  \dfrac{2}{5}}}}}}}\huge\checkmark

\large\text{Good luck on your assignment and enjoy your day!}

|x-3|&lt;2<br> |4x+1|&gt;0<br> |x-1|&lt;5<br> Ayudaaaaaaa pleaseeeee
Dafna11 [192]

Recuerda que

• |<em>x</em>| = <em>x</em> si <em>x</em> ≥ 0

• |<em>x</em>| = -<em>x</em> si <em>x</em> < 0

Necesitas considerar dos casos:

• si <em>x</em> - 3 ≥ 0,

|<em>x</em> - 3| < 1   ⇒  <em>x</em> - 3 < 1   ⇒   <em>x</em> < 4

• si <em>x</em> - 3 < 0,

|<em>x</em> - 3| < 1   ⇒   -(<em>x</em> - 3) = 3 - <em>x</em> < 1   ⇒   -<em>x</em> < -2   ⇒   <em>x</em> > 2

Entonces la solución consta de todos los números reales <em>x</em> tales que <em>x</em> > 2 y <em>x</em> < 4, o simplemente 2 < <em>x</em> < 4.

El método para resolver las otras desigualdades es el mismo.

|4<em>x</em> + 1| > 0   ⇒   4<em>x</em> + 1 > 0   o   -(4<em>x</em> + 1) > 0

…   ⇒   4<em>x</em> + 1 > 0   o   -4<em>x</em> - 1 > 0

…   ⇒   4<em>x</em> > -1   o   -4<em>x</em> > 1

…   ⇒   <em>x</em> > -1/4   o   <em>x</em> < -1/4

⇒   <em>x</em> ≠ -1/4

|<em>x</em> - 1| < 5   ⇒   <em>x</em> - 1 < 5   o   -(<em>x</em> - 1) < 5

…   ⇒   <em>x</em> - 1 < 5   o   -<em>x</em> + 1 < 5

…   ⇒   <em>x</em> < 6   o   -<em>x</em> < 4

…   ⇒   <em>x</em> < 6   o   <em>x</em> > -4

⇒   -4 < <em>x</em> < 6
