I have to do all these questions for my university course and I've done much harder ones than this but every time I come back to it I cannot get any other answer than the ones I've gotten thus far...There is my working out and the question. Please help me maths boffins as none of the provided help useful

The bit I don't understand in your working out is why you've put h+0.7+h+h=14.1? It states in the question that h is not equal to r, so 2h is not gonna equal h+r.

Right so let's do this from the beginning The elephant is 0.7 tonnes more than the hippopotamus E+0.7=H H=R (let us assume for now they're equal, we know they're similar though) E+H+R+C=15 E+H+R=14.1
where H=R E+2H=14.1
where E+0.7=H E+2(E+0.7)=14.1 3E+1.4=14.1 3E=12.7 E=4.2(rounded to the nearest decimal place)
where E=4.2 4.2+0.7=H H=4.9
now where H=R we would think that R=4.9 right? let's sub it back in to make sure ti does actually work E=4.2 H=4.9 R=4.9
4.2+4.9+4.9+0.9(for the cages)=14.9
remember H didn't exactly equal R? it was "roughly the same" so not exactly the same
You fool the hippopotamus isn't 0.7 tonnes heavier than the elephant you failed at the first step bro lol
you did it wrong buddy

so just increase the weight of the rhino by 1 ton
E=4.2 H=4.9 R=5.0 C=0.9
there that should work
I did it wrong? You are the one who failed on the first line. Elephant weighs 0.7 greater than hippo. E-0.7=H not E+0.7=H
Still waiting on a correct answer 😂😂 pretty sure the website is broken or something
Hmm, just a longshot, but in reality a rhino actually weighs more than a hippo. So if you switch around the two weights, is it correct? As you approximated R(squiggly equals)H, so then either variable could take either value, and in reality R>H, therefore R should take the larger final value?
