Write an equation that represents the line.
Use exact numbers

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
