Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.
Yes, the price is proportional you can figure this out easily by taking each price and dividing by the amount for example $2.10 / 6 = 0.35 , $2.80 / 8 = 0.35 , $5.60 / 16 = 0.35
Answer:
3+2=5
5u =12
1u=2.4
2u=4.8
3u=7.2
7.2 hour = 7 hours 12 min
4.8 hour = 4 hours 48 min
assuming first person work longer than the other
so first person worked 7 hours 12 min and second person worked 4 hours 48 min
