Answer:
A. 5x+6
Step-by-step explanation:
-(9x-18)+8x
-3x+6+8x (multiply across the -1/3)
5x+6 (combine 8x and -3x)
Answer:
<em>The actual distance between the two towns is 105 km</em>
Step-by-step explanation:
<em>Lets use a proportion for this scenario</em>
<em>1/30 = 3.5/?</em>
<em>We see that the numerator is multiplied by 3.5, from 1 to 3.5</em>
<em>So we do the same to the denominator</em>
30 x 3.5 is 105 km
So your answer is 105 km
