<h2>
The race is 1.2 miles long</h2>
Step-by-step explanation:
The first leg is 3/10 mi, the second leg is 1/2 mi, and the third leg is 2/5 mi.

Now we need to find length of race

The race is 1.2 miles long
Answer:
6+12b
Step-by-step explanation:
i took a test with this question and got it right
The answer would be 16
11 + (8-3)^2 - 20 = 16
The first thing I would probably do is distribute (multiply) the -5/2 into the parenthesis:
= (-5/2)x + (-20/2)
Notice how I am not putting the x into the fraction. This is to make it easier to see the slope-intercept form.
Lets simplify the (-20/2) and then add 7 to both sides:
y - 7 = (-5/2)x - 10
y = (-5/2)x - 3
Your answer would then be:
y = (-5/2)x - 3
y = mx + b
Since it is now in the requested format.
