Answer:
y=10r
Step-by-step explanation:
Ok so if each member of the jazz band sold the same amount of tickets, r, then we can write a linear equation (no exponents or anything). let y be the total number of raffle tickets sold. If they all sold the same amount, then we can simply multiply the number of people by the tickets they individually sold.
True, you can't simplify 1/2 any further
Negative one would be the answer
Scarf area is 8 small fabric area
8 x 0.25 x 0.25 =0.5.
7 scarf area would be
7 x 0.5 = 3.5
new fabric (large ) area is
2 x 0.25 = 0.5
7 scarf area divide by new fabric area
3.5 divide by 0.5 = 7 large pieces
The midpoint bisects PR, making it 2 equal halves.
