Answer:
8) C
9) I
Step-by-step explanation:
8)
Let's test some answer choices:
A) [tex]28/60+1/3=7/15+1/3=7/15+5/15=12/15\neq 29/63[/tex], so A is not the answer
B) [tex]4/27+25/36=16/108+75/108=91/108\neq 29/63[/tex], so B is not the answer
C) [tex]5/21+2/9=15/63+14/63=29/63[/tex], so C is the answer!
9)
Let's test some answer choices:
F) [tex]6^2-8/2=36-4=32[/tex], so F is not the answer(read the problem carefully, it asks which expression is NOT equal to [tex]32[/tex])
G) [tex]30/2+5^2-8=15+25-8=32[/tex], so G is not the answer
H) [tex]30+4^2/(2+6)=30+16/8=30+2=32[/tex], so H is not the answer
That leaves I, so I must be the answer([tex]8^2/4-2=64/4-2=16-2=14[/tex])
Therefore, c is the answer to 8) and I is the answer to 9) and we're done!
