Answer:
17.7
Step-by-step explanation:
This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.
100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540
190 +19x + 13 = 540
203 + 19x = 540
19x = 337
x = 17.7
Answer: C
Step-by-step explanation:
We know that a relation is any set of ordered pairs, but a function is when there is only one y value for x value.
So, basically, if a graph is a function, it is a relation as well.
Let’s check if this is a function.
We can use the vertical line test- if we draw a vertical line through any point on the graph and it only intersects one point, it is a function
In our case, it passes the vertical line test.
Therefore, it is both a function and a relation, which corresponds to letter C.

Not necessarily. For example, you can have a rectangle whose dimensions are 12 and 6. Length is 12 and 6 is the width.
The area (length × width) of the rectangle will be 72.
The perimeter of the rectangle (2l + 2w) will be 36.
So, in this case, the area was double the perimeter and the perimeter was not greater than the area of the shape.
Step-by-step explanation:
The number of students in each bus is s.
There are 6 buses.
The number to fill them is 6s and we have 5 more students in a van.
Total number is 221.

Answer:
115 of them are not minivans
Step-by-step explanation:
Because every 7 vehicles has 2 minivans and other vehicles, so 5/7 are not minivans 166x5/2=115
Hope this works! :)
