Answer:

9' 9"

Step-by-step explanation:

Think of it as a decimal. Since 3 is .25 of 12 (or one foot) than it is 15.25. And since 6 is half of 12 it is 5.5. 15.25-5.5=9.75 or 9' 9" once we put it back into terms of feet and inches.

Simplify 5/8x -2y +3/4x-8y

Answer:

On simplification, $\frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$

Step-by-step explanation:

Here, the given expression is:

$\frac{5}{8}x - 2y + \frac{3}{4}x -8y$

Now, we can perform operations only on LIKE TERMS,

So, in this expression, separate the like terms we get:

$\frac{5}{8}x - 2y + \frac{3}{4}x -8y = \frac{5}{8}x + \frac{3}{4}x - 2y -8y\\= (\frac{5}{8} + \frac{3}{4})x -(2y + 8y) = (\frac{5 + 3(2)}{8}) x - (10y)\\= (\frac{11}{8}) x - 10y\\\implies \frac{5}{8}x - 2y + \frac{3}{4}x -8y = (\frac{11}{8}) x - 10y$
