Answer:
B 53/20
Explanation:
| -4/5-1/10| + |-3/4 +5/2|
We need to get common denominators. The first absolute value has a common denominator of 10
| -4/5-1/10|
| -4/5*2/2 -1/10|
|-8/10 -1/10|
|-9/10|
Absolute value means take the positive value
9/10
We need to get common denominators. The second absolute value has a common denominator of 4
| -3/4 +5/2|
|-3/4 +5/2*2/2|
|-3/4 +10/4|
|7/4|
Absolute value means take the positive value
7/4
9/10 + 7/4
We need to get a common denomintor, that would be 20
9/10*2/2 + 7/4*5/5
18/20 + 35/20
53/20
