34.215 kilometers you move the decimal to the left three places because Kilo means 1000 and there are 3 zeros in 1000. you move left because Kilometer is bigger than meter.
y = 45
multiply both sides by 5 to eliminate the fraction
90 = 2y ( divide both sides by 2 )
45 = y
1. Start at 2, then go up one over two for the next point.
2. Start at -1, then go up two over one for the next point.
<em>GCF = 45</em>
- Step-by-step explanation:
<em>90 = 9×10 = 3²×2×5</em>
<em>135 = 45×3 = 9×5×3 = 3²×5×3 = 3³×5</em>
<em>GCF = 3²×5 = 9×5 = 45</em>
