1/2x - 4 = 1/3x + 5​
Mamont248 [21]

Answer:

X = 54

Step-by-step explanation:

Let's solve your equation step-by-step.

1/2x−4=1/3x+5

Step 1: Subtract 1/3x from both sides.

1/2x−4−1/3x=1/3x+5−1/3x

1/6x−4=5

Step 2: Add 4 to both sides.

1/6x−4+4=5+4

1/6x=9

Step 3: Multiply both sides by 6.

6*(1/6x)=(6)*(9)

x=54

On an average day a horse might drink 50l a sheep might drink 4l and a chicken might drink 200ml. How much water would a farm wi
aksik [14]
50 L X 3 = 150 L (water value for horses)
4 L X 15 = 60 L (water value for sheep)
200 mL X 12 = 2,400 mL or 2.4 L (water value for chickens)
Add them all together.
150 + 60 + 2.4 = 212.4 L of water is used daily
