1 kilometre= 0.621 miles
400km= 400*0.621 miles
=248.4 miles
(3x+20)+(8x-16)=180
Combine like terms:
11x+4=180
Then solve
11x=176
X=16
6. The formula for slope is y=mx+b. Your B is 3, and your M is 6. B= Y intercept and M=Slope

Answer:
B.
Step-by-step explanation:
From the number line, we can see that the blue line points to all values to the <em>left</em> of 5. This means all values <em>less than</em> 5.

Therefore, the inequality that represents the graph is all values <em>less than or equal</em> to 5.
In notation, this is:

The answer is B
