Hi! i really need with the following questions, show your work! if anyone is willing to me! you and someone me. solve for x. 1) (2x+1/3)=2x 2)jeydas soccer team sells t-shirts to raise money for new equipment. for each t-shirt sold, the team raises $8. parents also make a donation of $100 toward equipment. what is the equation that represents the total amount raised,y, if x-t shirts are sold? 3)mercury is the closest planet to the sun at a distance of 36 million miles.the closest star to the sun is próxima centauri, which is 4.24 light years away. a light year is 5.9*10^12 miles. part a) write the distance in miles form mercury to the sun in scientific notation. part b) how many miles from the sun is proxima centaurl? express your answer in scientific notation. part c) about how many times greater is the distance from the sun to proxima centaurl compared to the distance from the sun to mercury? express your answer in scientific notation.

You can solve this with proportion

1)    For 2h

9/2 mile : 3/4h = x mile : 2h => (3/4)x=(9/2)*2 => (3/4)x=9 => x=9*(4/3)= 12miles

For 3h => (3/4)x=(9/2)*3 When we divide equation with 3 we get

x/4=9/2 => x=(9/2)*4=18 miles

2)  2 combine : 320 acres = 7 combines : x acres +: 2x= 320*7 =>

x= (320*7)/2 = 160 * 7 = 1120 acres

Good luck!!!
