Twenty eight miles per hour
Step-by-step explanation:
a.) 9
When you divide with a fraction you do the reciprocal of the fraction (basically flipping numerator and denominator) then multiplying (since the opposite of division is multiplication.
So if you flip

It would be:

9/1 is the same as 9 so:
1 times 9 = 9
b.) 15
Same thing like we did above, just do the reciprocal the multiply.

Becomes

5/1 is the same as 5.
3 times 5 = 15
By observing the graph we can note down the following things about the boundary line:
- It has a positive slope.
- It cuts the X-axis at

- It cuts the Y-axis at $(0,-x)$, where $|x|$ is some value less than 2 but greater than 1.
Let's look at the shaded region. The origin lies inside it.
Thus, the point $(0,0)$ satisfies the equation of the region.
Upon putting it in the options, we find that only two options: 2 and 4 satisfy the inequality $0<5$
Now find the Y-intercept of the boundary line:
Option 4) $0-2y=5$
$y=\frac{-5}{2}<-2$
Since it is smaller than -2, it is the wrong option.
Hence, correct option is $\boxed{x-3y<5}$

The answer should be 5 because if there were 100 it would be 20
