we know that

1 lap around the school track is 5/8 mile

so

by proportion

Find how many miles corresponds to3\frac{1}{2} laps

3\frac{1}{2}\ laps=\frac{3*2+1}{2} =\frac{7}{2}\ laps

\frac{(5/8)}{1} \frac{miles}{lap}= \frac{x}{(7/2)} \frac{miles}{lap}\\ \\x=\frac{5}{8}*\frac{7}{2}\\ \\ x=\frac{35}{16}\ miles\\ \\x=2\frac{3}{16}\ miles

therefore

<u>the answer is</u>

2\frac{3}{16}\ miles

Solve for x . x/2 + 1.1= -2.1
raketka [301]

Answer: x = 1.6

Step-by-step explanation:

Start by Identifying what you need to keep, in this case that would be X. In order to solve for x, you would need to get rid of any co-efficients. (example: +1.1) To get rid of them, you have to do the opposite action of what it's doing to the equation. (subtraction)

1.1- (-2.1) = 3.2 (if you subtract a negative, it turns positive/ you add) leaving you with x/2 = 3.2.

Now that we have our coefficient out the way, we have to get rid of the division so we can <u>only</u> solve for x. We do that by dividing the remainder of the equation by 2

3.2/2 = 1.6

Leaving us with the answer, x = 1.6
