U should subtract the first number and the second one together and see what you get
In 1 hour (60 minutes), you earn = $6
so, 1 min, it is = 6/60 = 1/10
Now, in 2 min, it would be = 1/10 * 2 = 1/5 = 0.20
So, you earn $0.20 in 2 minutes
Hope this helps!
Well first you would have to do the distributive property... d+4d+ 24=-1. Then you would have to combine like terms. -----> 5d+24=-1------> 24- (-1) =25... now divide 5 from 5 and 25. So d=5... I'm pretty sure this is right...
10x^6y^3 + 20x^3y^2 / 5x^3y =
5x^3y (2x^3y^2 + 4y) / 5x^3y=
<span>2x^3y^2 + 4y
</span>
First you find what the expressions 10x^6y^3 and 20x^3y^2 have in common, and that is 5x^3y, which is the same as the denominator, so you can easily divide them and get 1.

Answer: 8 hours
Step-by-step explanation:
Let x be the time taken by each person to paint the fence.
Given: Tom and Becky can paint Jim's fence together in 12 hours.
Since all people paint at the same rate, then we have the following equation ;-
Thus, the time taken by each person to paint the fence alone = 24 hours
Now, the time taken by all three paint together:-
Hence, it would take 8 hours if all three paint together.
