Subtract the mixed numbers by finding the common denominator. five and seven tenths minus one and two fifths equals blank

five and three tenths
four and nine tenths
four and three tenths
four and nine fifteenths

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

oh

nu stiu chiar nu stiu sa o fac

the anwser is x< -17/2
