Geometry quiz! not my strong suit. help please
Maksim231197 [3]

Assuming PQRS is a parallelogram, we have PQ = RS, and angles S and R are supplementary so their measures sum to 180°.

So

5<em>x</em> = <em>x</em> + 12

4<em>x</em> = 12

<em>x</em> = 3

→   PQ = 5<em>x</em> = 15

and

12<em>z </em>° + 6<em>z</em> ° = 180°

18<em>z</em> ° = 180°

<em>z</em> = 180/18 = 10

→   m∠<em>S</em> = 12•10° = 120°

Ab over 2 equal 2a minus 1,express a in terms of b
sasho [114]

\frac{ab}{2} = 2a - 1

2(\frac{ab}{2}) = 2(2a - 1) <em>multiplied both sides by 2 </em>

ab = 4a - 2 <em>distributed the 2 on the right side</em>

ab - 4a = -2 <em>subtracted 4a from both sides</em>

a(b - 4) = -2 factored out "a" from the left side

a = \frac{-2}{b - 4} <em>divided (b - 4) on both sides</em>

Answer: a = \frac{-2}{b - 4}
