No, because BC and BD are not the same lengths. If AB = BC, then AB and BD are not the same lengths -> ABDE is not a rhombus.
How do u write 650 as a fraction......650/1
** if u have a whole number, and u want to make it a fraction, just put it over 1
Answer:
the values of x, y and z are x= 2, y =-1 and z=1
Step-by-step explanation:
We need to solve the following system of equations.
We will use elimination method to solve these equations and find the values of x, y and z.
2x + 2y + 5z = 7 eq(1)
6x + 8y + 5z = 9 eq(2)
2x + 3y + 5z = 6 eq(3)
Subtracting eq(1) and eq(3)
2x + 2y + 5z = 7
2x + 3y + 5z = 6
- - - -
_____________
0 -y + 0 = 1
-y = 1
=> y = -1
Subtracting eq(2) and eq(3)
6x + 8y + 5z = 9
2x + 3y + 5z = 6
- - - -
______________
4x + 5y +0z = 3
4x + 5y = 3 eq(4)
Putting value of y = -1 in equation 4
4x + 5y = 3
4x + 5(-1) = 3
4x -5 = 3
4x = 3+5
4x = 8
x= 8/4
x = 2
Putting value of x=2 and y=-1 in eq(1)
2x + 2y + 5z = 7
2(2) + 2(-1) + 5z = 7
4 -2 + 5z = 7
2 + 5z = 7
5z = 7 -2
5z = 5
z = 5/5
z = 1
So, the values of x, y and z are x= 2, y =-1 and z=1
A. If there are only green and yellow M & M’s in the bag, what is the smallest number of
M & M’s possible? 7 M & M’s total
b. If there are 84 M & M’s in the bag all together, how many are green? 24 green ones
c. If red M & M’s were added to the bag in part b to get a total of 100, what is the ratio of green to yellow to red? 6: 15: 4
Line is different from line segment or a ray. The given lines MR and XY are best described by: Option A: The lines intersect at a 90° angle.
To get to know about intersection of MR and XY, we need to know what a line is.
<h3>What is line, line segment and a ray?</h3>
- A line usually refers to infinite lenghted straight line in the Euclidean space.
- A line segment is a segment (of finite length) of a line.
- A ray is has fixed on endpoint, but it extends infinitely from the other endpoint, so no other endpoint at all.
<h3>When does two lines intersect?</h3>
If they are not parallel (having 0 degree angle between each other) and not coincident (not lying over each other), then those two lines always intersect.
Since the considered lines MR and XY are said to be perpendicular (having 90° angle between them, thus, they will intersect each other).
Therefore, the given lines MR and XY are best described by: Option A: The lines intersect at a 90° angle.
