Answer:
26.25 km
Step-by-step explanation:
Step up a portion. Here, 4 cm is to 7 cm as 15km is to x km
4/7 = 15/x
Now solve for x by cross multiplying
4x = 105
x = 105/4 (divide by 4 on both sides)
x = 26.25 km (simplify)
Look at the picture.
Therefore we have the equation:
10y - 29 = 7y + 19 <em>add 29 to both sides</em>
10y = 7y + 48 <em>subtract 7y from both sides</em>
3y = 48 <em>divide both sides by 3</em>
y = 16
3x + 7 = 5x - 21 <em>subtract 7 from both sides</em>
3x = 5x = -28 <em>subtract 5x from both sides</em>
-2x = -28 <em>divide both sides by (-2)</em>
x = 14
