Yes so first the ratio is 3 (30/10)
so then you take the original ratio (9/10) and multiply the 9 by 3 (27)
30+27=57 so yes it is
The slope is half, since when the equation is divided by two so that the y value is one, the x coefficient is half, so the slope is half.
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation 3/r-(5/r+3)=0
5 Simplify — r 3 5 — - (— + 3) = 0 r r , for short the answer = -2/3 = -0.667
You can use 920 divided by 20. This would give you 46. You get 920 by Round 921 to the nearest tens. You also get 20 by rounded it to the nearest tens
