If it’s only 7 ppl you would have to double the amount of people meaning that 14 people shook each other’s hands but not quite cause they shook each other’s hands 7•14=98/4=25

Answer:

\boxed{\bold{One \ Solution}}

Step-by-step explanation:

  • <u>Solve equation to find answer(s)</u>

<u></u>

Combine: 6z - 3z = 3z

\bold{3z-7=-2+3}

Add: -2 + 3 = 1

\bold{3z-7=1}

Add 7 to both sides:

\bold{3z-7+7=1+7}

Simplify:

\bold{3z=8}

Divide both sides by 3:

\bold{\frac{3z}{3}=\frac{8}{3}}

Simplify:

\bold{z=\frac{8}{3}}

East of Star, the railroad tracks intersect highway 23o as shown above. If 1=133 , find 2.
GrogVix [38]
Hi there.

These two angles sum up to be 180 degrees, so they are supplementary angles. Now, since these angles sum up to 180 degrees (to form a straight line), we only have to subtract 133 from 180 to find angle 2's measurement.

180 - 133 = 47

Angle 2's measurement is 47 degrees.

Voila! 

I hope this helps! Have a great day. :)
