Answer:
B. x > 4
Step-by-step explanation:
12 < 8 + x
12-8 < 8-8 +x
12-8 < x
4 <x
x > 4
See the picture attached to better understand the problem
we know that
A quadrilateral is called Cyclic quadrilateral <span>if its all vertices lie on the circle.
</span><span>The opposite angles of a Cyclic - quadrilateral are supplementary
</span>so
∠A+∠C=180°
and
∠
B
+∠D=180°
therefore
the answer is<span>
C) The sum measure of ∠B and ∠D equals 180°</span>
Answer: 53 points
Step-by-step explanation:
Let the number of points gotten by Kate be represented by x.
Since we are given the information that Kevin got 52 points which was 54 points less than 2 times that of kates points. This can be formed into an equation as:
(2 × x) - 54 = 52
2x - 54 = 52
2x = 52 + 54
2x = 106
x = 106/2
x = 53
Kate got 53 points
Answer:
x=0 , y=0
Step-by-step explanation:
2x +6y= 8 .....eqn 1
4x +12y= 16....eqn2
we multiply eqn 1 by 2.. because we want at least one variable to have the same coefficient so we can simply.
2x +6y =8... ×2
will give you 4x +12y = 16....eqn 3
so now we subtract eqn 2 from eqn 3
4x + 12y= 16
- 4x + 12y = 16
_____________
0 + 0 = 0
therefore x = 0 and y= 0
