Anna has a total of 40 goldfish in her aquarium, some are orange and some are black. The number of orange goldfish is 5 more than
twice the number of black goldfish. Which system of equations below can be used to describe the number of black and orange
goldfish in Anna's aquarium?

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
