If all the girls danced but only two-thirds of the boys danced how many children danced in all
2 answers:
If theres 43 kids, 25 girls and 18 boys...
If 2/3rds of all the boys danced than that's 12
If all the girls danced thats 25
12+25= 37
37 kids danced, then.
5/6 of the children
I feel as if there is information missing from the question though such as quantities.

Answer:
3(-2-3x) = 9x-4
-6-9x = 9x-4
-6+6-9x = 9x-4+6
-9x = 9x+2
-9x-9x = 9x-9x+2
-18x = 2
-18x÷(-18) = 2÷(-18)
x = -(1/9)
Thank you

The answer is 60. You can find this out by finding the least common multiple of 10 and 12, which is 60 because 10x6=60 and 12x5=60. Hope this helps :)
10% as a decimal would be .10
65 x6 = 390
80 x 3= 240
390+240 = 630
For perimeter you just add the sides up, so 15+12+9 which = 36
