Okay, so to find like denominators you need to find a number that both denominators go into. For 15, they both go into 45. 9 goes in 5 times and 15 goes in 3 times. So multiply their numerators by 5 and 3. It would be 25/45 for 5/9 and it would be 12/45 for 4/15. Do the same for 16 and 17, for 16 they both go into 42 and for 17 they both go into 42.

FG=8x+4. If GH=4x+8 and FH=15x-9, then what does FH=?
Mashcka [7]
So 8x+4+4x+8=15x-9

Combine like terms.

12x+12=15x-9

Add 9 to both sides.

12x+21=15x

Subtract 12 from both sides.

21=3x

Divide both sides by 3.

x=7

Now plug in 7 for x in 8x+4.

8(7)+4

56+4

A water tank is being filled by pumps at a constant rate. The volume of water in the tank V, in gallons, is given by the equatio
mamaluj [8]

Answer:

65 gallons per minute

Step-by-step explanation:

The total volume of the tank at any given time is given by the equation:

V(t) = 65t + 280

In order to find the rate of change of volume, we can simply differentiate this equation with respect to time. This will give us the rate of change of the volume or the rate at which water is being pumped into the tank.

Differentiating the above equation we get:

V'(t) = 65

So we can see that the rate at which water is being pumped into the tank is 65 gallons per minute
