4/5-3/7. First they need the same denominater: 4/5(7)=28/35, 3/7(5)=15/35. 28/35-15/35. Now subtract numerators: 28-15=13. So your answer H. 13/35 :)
x for 2 pointquestion y for 4 point question
x+y=40
2x+4y=100
x=40-y
80-2y+4y=100
2y=100-80
2y=20
y=10
x=40-10=30
5 + 3{96 + 20 + 4}
5 + 3{116 + 4}
5 + 3{120}
5 + 360
365
okay so you would first turn everything into fractions 2 3/4= 11/4 + 5/6
next you would change the denominators so they match 11/4 x 6 = 66/24
5/6 x 4 = 20/24
so then you would add 66/24 + 20/24 = 88/24 = 11/3
11/3 is your answer
hope this helps!
