Best ResponseYou've already chosen the best response.0I think you may have made a typo in typing the equation, because .4 + .5 does not look right. The way it is written there, y = .4.

Best ResponseYou've already chosen the best response.0let's see. 0.5y+10.3=0.9 (here i distributed, then added) 0.5y+0.7=0.9 0.5y=0.2 hm... I get 2/5

Best ResponseYou've already chosen the best response.0I think he meant = .4y + .5. That produces an answer of 2.

Best ResponseYou've already chosen the best response.0Anyway, explanation, .5(y+2) .3 = .4y + .5 .5y + 1  .3 = .4y + .5 (Distribution) .5y + .7 = .4y + .5 .5y = .4y  .2 .1y = .2 y = .2/.1 y = 2 If that's what your book says, I think the typo is in the book. Point it out to your teacher for extra credit.

Best ResponseYou've already chosen the best response.00.5 is the same as .5. so 10.3 is the same as 1.3 which is 0.7. I double checked on my calculator
