You'll need to use parentheses here to convey this problem accurately to possible helpers.  Unsure of whether you mean (9/2)k -3 or  9 / (2k-3).

I will assume that you mean:

    9           4
------- = ---------
2k-3        k+1

Cross mult:  9k+9=8k-12, so k= -21.

If that's not what you expected, then try again to present the problem without ambiguities.

A tank currently holds 5 gallons of water. It is being filled at the rate of 1/4 gallon per minute. How long will it take for th
Verdich [7]
So we know the tank already has 5 gallons and we need 9. This means we need 4 more gallons in order to fill up the tank.

If 1/4 gallon is being filled per minute we need to find out how many 1/4 gallons makes up 4 gallons in total.

4 of the 1/4 gallons makes up 1 whole gallon. So since we need 4 whole gallons we would need 16 of the 1/4 gallons.

This means that it will take 16 minutes for the tank to hold 9 gallons of water.

Whats 87 less than the quotient of an unknown number and 43 is -75?
erastovalidia [21]
<span>87 less than the quotient of an unknown number and 43 is -75
Converting that to mathematical equation:
87 - (x / 43) = -75

Evaluating the equation, we can the value of x.
87 - (x/43) = -75
-x/43 = -75 - 87
-x/43 = -162
-x = -6966
x = 6966</span>
