Ateam has 50 jerseys .there are 35 medium sized jerseys. what us the percentage of medium jerseys

The percentage of medium jerseys is 70 percent because 35/50 is 0.70 and if you move the decimal place twice to the right you get 70%

1) add 6 to 24, write the rest of the equation 10-2x= 30 subtract 10 from 30 2x=20 divide 20 by 2 and x=102) add 3 to -9 write the rest of the equation 4x+3=-6 subtract 3 from -6 4x=-9 x= -2.25  i don't know the rest sorry
