Answer:
A
Step-by-step explanation:
We know a number is an expression when it is:
1) NOT greater/ less than something else
2) NOT equal/ not equal to something else
The only answer choice that satisfies the above is A.
15/24
4 2/3=(4*3)+2/3=14/3
simply 15/24
15/3/24/3=5/8
refine
5/8*14/3
8 and 14 share a factor of 2
8/2=4
14/2=7
refine
5/4*7/3
5*7/4*3
35/12
convert to mixed number
35/12=2.11
2 11/12
the answer is 2 11/12
Answer:
d=1
Step-by-step explanation:
Factor d^2 - 2d - 8 into (d-4)(d+2)
Move -2/d+2 onto the other side, changing it into 2/d+2.

Let the empty side equal zero.
Add 3/d-4 and 2/d+2

Then add that to -3d.

Multiply 0 by d+2 and d-4 to get 2d-2 by itself.
2d=2
d=1
I can't edit the equation, but it's d-4 althroughout the question. Sorry for being so slow.
