Asap! a biologist is to set up an aquarium in his laboratory. he intends to buy 11 piranhas and 5 sharks. he has a budget of £200. if p represents one piranhas and s one shark, write down an equation for the price of one piranhas in terms of the price of sharks.

p = (200 -5s)/11

Step-by-step explanation:

I think you meant p is the price of piranhas, and a is the price of one shark.

You have:

11p + 5s = 200

11p = 200 - 5s

p = (200-5s)/11

Does that help? ;)

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

you can't solve x because it is 2 linear equation and you only have one equation
