A) 25/28

B) 9/10

C) 3/20

D) 0

E) 12

F) 11 1/12 (also as 133/12)

G) 1 7/60 ( also as 67/60)

H) 11 1/12 It's the exact same question as the other one sooo

I) -3/16

J) -53/80

Step-by-step explanation:

Just find the LCD and combine

See below.

Step-by-step explanation:

A) 3/4 + 1/7 = 21/28 + 4/28 = 25/28

B) 2/5 + 3/6 = 12/30 + 15/30 = 27/30 = 9/10

C) 2/5 - 1/4 = 8/20 - 5/20 = 3/20

D) -2/6 - (-1/3) = -1/6 + 1/3 = 0

E) 5 ½ + 6 ½ = 5 + 6 + ½ + ½ = 12

F) 8 ¾ + 4 ½ - 2 ¹/6 = 8 + 4 - 2 + 9/12 + 6/12 - 2/12 = 10 13/12 = 11 1/12

G) 3/4 + 1/5 + 1/6 = 45/60 + 12/60 + 10/60 = 67/60 = 1 7/60

H) 8 ¾ + 4 ½ - 2 ¹/6 = 11 1/12

I) -3/12 - (-1/16) = -1/4 + 1/16 = -4/16 + 1/16 = -3/16

J) -3/48 - (4/5) + 1/5 =​ -15/240 - 192/240 + 48/240 = -159/240 = -53/80

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
