How do you solve the inequality 6y+3&gt; -18x
Alex17521 [72]
6y + 3 \ \textgreater \  - 18 x

Subtract 3 from both sides:

6 y + 3 - 3 \ \textgreater \  - 18 x - 3

6y \ \textgreater \  - 18 x - 3

Dividade both sides by 6 :

\frac{6y}{6} \ \textgreater \   \frac{-18x-3}{6}

y \ \textgreater \  \frac{-18x-3}{6}

hope this helps!

ludmilkaskok [199]

Given:

The bases of trapezoid measuring 4 m and 12 m.

To find:

The median of the trapezoid.

Solution:

The median of the trapezoid is the average of its bases.

\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}

The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:

\text{Median}=\dfrac{4+12}{2}

\text{Median}=\dfrac{16}{2}

\text{Median}=8

Therefore, the correct option is C.
