Answer:
C. I & III
Step-by-step explanation:
I simplifies to ...
2(6x +15 -5x) +4 = 40
12x +30 -10x +4 = 40
2x +34 = 40
__
II simplifies to ...
40 = 2(15 -x) +4
40 = 30 -2x +4
40 = -2x +34 . . . . . . not equivalent to I (sign of x-term is different)
__
III simplifies to ...
12x +30 -10x +4 = 40
2x +34 = 40 . . . . . . equivalent to I
___
I & III are equivalent
Answer: GCF = 6 aquariums
Step-by-step explanation:
Due to the lack of information I assume these are fractions so for 5/35 we times it by 21 and 21 by 35 so they have the same denominator so now we got 105/735 and for 21 we get x/735 so now You put 105/735 and divide by 35 so we get back down to 21 for
3/21 for part 1
Now for part 2 again 15 times 20 and 20 times 15 to equal out the denominators so now we have 240/300 and x/300 so now plug 240 into x and divide down by 15 and now we get
16/20 for part 2
LMK if I am wrong I highly doubt it
