Which equation can be used to find the number of fish in the pond on June 1?

olga_2 [115]

Answer: The required equation is $f-52=63$ and the number of fishes in the pond on June 1 = 115

Step-by-step explanation:

Given: The number of fishes in pond on July 1 = 63

Also, it is said that the number of fishes in pond on July 1 is 52 fewer(lesser) than the number of fishes in pond on June 1.

Let f be the number of fishes in pounds on June 1.

then the required equation will be

$f-52=63$

Now, add 52 on both the sides of the equation, we get

$f=63+52\\\Rightarrow\ f=115$

Answer:

h(g(x)) = (1/5)x² +4/5
