Answer:
45°
Step-by-step explanation:
Because every angle in a square is 90° and the diagonal is bisecting the angle so we have 45°
So to find average, we add up the values, and divide it by how many values there are in total.
27 + 12 + 31 + 19 + 23 + 11 + 17 = 140.
There are 7 numbers. Which means we divide 140 by 7.
140 / 7 = 20 is the average.
Also, if you notice, most of the numbers "kind of" circulate around 20.
The shape in the figure has 6 sides
The choice that describes the group the shape belongs to is (a) parallel sides, acute angles
<h3>How to determine the group of the shape?</h3>
From the figure, we have the following highlights
- The shape has 6 sides
- The direct opposite sides are equal
- The direct opposite sides are parallel
- The measure of angles between adjacent sides are less than 90 degrees i.e. acute angles
The above highlight mean that:
The shape belongs to parallel sides, acute angles group of shapes

Answer:
Hi! The correct answer is (1448/3, 686)
Step-by-step explanation:
<u><em>~Solve for the first variable in one of the equations, then substitute the result into the other equation~</em></u>
Answer:
1) When x is 1, y is 4, and vice versa
2) When x is -6, y is 42, and when x is 7, y is 114
3) When x is -2, y is 2, and when x is 8, y is 42
Step-by-step explanation:
1)
which can be rearranged as 
.
Substituting this lone y into the first equation, you get:
Move everything to one side:
Factor:
2)
which can be rearranged as 
.
Let's use elimination this time and subtract the first equation from the second:
Factor:
3)
Let's set the two equations equal to each other through substitution:
Move everything to one side:
Factor:
Hope this helps!
