Wonder Waves Aquarium just opened a new Tropics Wing, with a large main tank and a small observation tank. There are 75 fish in the large tank, 25 of which are angelfish. There are 25 fish in the small tank, 5 of which are angelfish. Do the tanks have the same ratio of angelfish to total fish?

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

set the two equations for y equal to each other. solve for x. this will be the x-coordinate for the point of intersection. use this x-coordinate and plug it into either of the original equations for the lines and solve for y.
