Answer:

The answer is C. -3 \frac{3}{20}

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 \frac{3}{20}

Hope this helps!

Answer:

-2\frac{3}{4}

Step-by-step explanation:

Given: −9/4 + |−8/5| − 2 1/2

Rewriting: -\frac{9}{4} + |-\frac{8}{5} |-2\frac{1}{2}

Absolute value: -\frac{9}{4} + \frac{8}{5} -2\frac{1}{2}

Improper fractions: -\frac{9}{4} + \frac{8}{5} -\frac{5}{2}

Common denominators: -\frac{45}{20} + \frac{40}{20} -\frac{50}{20}

Solving from left to right: -\frac{5}{20}  -\frac{50}{20}

Solving from left to right part two: -\frac{55}{20}

Simplifying: -\frac{55}{20}=  -\frac{11}{4} =-2\frac{3}{4}

Answer: -2\frac{3}{4}

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

Use the diagram to determine which statement is true
Dahasolnce [82]

The answer is d.

Finding area of ABCD :

  1. Find side length
  • side = √3² + 4²
  • side = 5

    2. Apply formula to find area

  • area = 5²
  • area = 25

Finding area of GHIA :

  • area = 4²
  • area - 16

Finding area of DEFG :

  • area = 3²
  • area = 9

Now, let's see whether is true.

  • Area (ABCD) - Area (GHIA) = Area (DEFG)
  • 25 - 16 = 9
  • 9 = 9

∴ Hence, it is proved √
