Answer:
18
Step-by-step explanation:
Just divide both sides by - 64

To solve for x, we have to remember to isolate the variable.

For 1/2, we can make that 0.5, since their values are equivalent. Our equation:

Let's distribute the 0.5 first.


Now, let's simplify the right side of the equation. We have to distribute the negative to 3x and 1.

Then, we simplify the entire expression.


Our equation now:

Let's add 3x to the right and 3x to the left to simplify the -3x on the right side of the equation.


Let's do the same thing we did in Step 3 to 1.5. Subtract 1.5 on both sides of the equation.


Finally, we divide both sides by 6 to isolate x.


1 hour = 60 minutes
27/60 = 0.45 miles per minute
Set up a ratio 3 3/4 = 15/4 and 1 1/2 = 3/2 so
((15/4miles) / (3/2hours)) = xmiles/4hours solve for x
so x = 4hours*((15/4miles)/(3/2hours)) = x miles
the hours cancel and you are left with x miles = 10miles
