Answer:
Cathy was right ( kinda)
Step-by-step explanation:
let the dimension of the small one be 2a : 2b : 2c
then the dimension of the big one be 3a : 3b : 3c
volume of small: 2a*2b*2c = 8 abc
volume of big: 3a*3b*3c = 27 abc
volume ratio: big/ small = 27/8 = 3.375
-> big one hold 237.5% more than small
-> Cathy was right ( kinda)
Answer:
-48
Step-by-step explanation:
you put the -6 in the place of a, and put 7 in the place of x. you get -6-6x7. 6x7 is 42. -6-42 is -48.
+ 474 equals
483.
First, multiply 3 two (3x3) times to get 9. Your problem should look like: 9 + 474.
Second, add 9 + 474 to get 483, which is the correct answer.
