Aiko works in the fish department of a pet store. She is asked to drain, clean, and refill two reef tanks. The first tank holds 175 gallons of water, and the second tank holds 200 gallons of water. The hoses that she
uses drain the tanks at a rate of 25 gallons of water per hour.
1. Write an equation for each tank that represents the total amount of water in gallons in the tank, y, in
terms of the number of hours, x, that the tanks are draining.
2. How much water is in each tank after 3 hours?
3. Write your equations in the first row of the table. Then, complete the table of values for the linear system.

mr. graef told us it is 13 pints

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
