The answer for this question is x=2,-7
Rt-3f=12 subtract rt from both sides
-3f=12-rt divide both sides by -3
f=(rt-12)/3
Answer:
We use ratio and proportion
If EC$ 2.50 = US$ 1.00
Then EC$ 20.00 = US$ 20 × 1 / 2.50

Answer:
40! Seconds
Step-by-step explanation:
Calculation for After how many seconds will the two fish tanks have the same amount of water
First step
Based on the information given let the equation be :
150-1/2x=120+1/4x
Second step
Now let solve for x which means that x will be the number of second by multiplying both side by 4
4(150-1/2x)=4(120+1/4x)
=600-2x=480+x
Third step
Let Add 2x on both side
600=480+3x
Third step
Let Subtract 480 on both side
600-480=480-480+3x
120=3x
Last step is to divide both side by 3
120/3=3x/3
40=x
Hence:
x=40 seconds
Therefore After 40 seconds the two fish tanks will have the same amount of water.
