What is the value of the expression? ( 5/2 ) ^2 +3/4 ^3

Mathematics
1 answer:
NeX [460]3 years ago
7 0

5/2 ^2 =  6 1/4 = 6.25

3/4^3 =  27/64 = 0.4201875

6 1/4 + 27/64 = 6 43/64  (mixed number)

6.25 +0.421875 = 6.671875 (decimal)


 not sure what format you need, since the question was in fraction form, I think you need to answer using a mixed number though.

Answer:

x=94

Step-by-step explanation:

I hope I'm correct. Here's my explanation: x+9 and 2x-111 would equal 180, hence the line (supplementary). So x+9+2x-111=180

x=94

hope this helps.
