Answer:

[tex]-2\frac{3}{4}[/tex]

Step-by-step explanation:

Given: −9/4 + |−8/5| − 2 1/2

Rewriting: [tex]-\frac{9}{4} + |-\frac{8}{5} |-2\frac{1}{2}[/tex]

Absolute value: [tex]-\frac{9}{4} + \frac{8}{5} -2\frac{1}{2}[/tex]

Improper fractions: [tex]-\frac{9}{4} + \frac{8}{5} -\frac{5}{2}[/tex]

Common denominators: [tex]-\frac{45}{20} + \frac{40}{20} -\frac{50}{20}[/tex]

Solving from left to right: [tex]-\frac{5}{20} -\frac{50}{20}[/tex]

Solving from left to right part two: [tex]-\frac{55}{20}[/tex]

Simplifying: [tex]-\frac{55}{20}= -\frac{11}{4} =-2\frac{3}{4}[/tex]

Answer: [tex]-2\frac{3}{4}[/tex]

Hope this is correct and helps, have a nice day! :D

Answer:

The answer is C. -3 [tex]\frac{3}{20}[/tex]

Step-by-step explanation:

- 9/4 + 8/5 - 5/2

(The absolute value symbol makes the negative a positive, and 2 and 1/2 is 5/2 in improper form)

- 9/4 + 8/5 - 10/4

-19/4 + 8/5

-95/20 + 32/20

-63/20

-3 [tex]\frac{3}{20}[/tex]

Hope this helps!
