Which ordered pair is the solution to the system
equations?
5 -5x – 3y = 12
1 = 0
y = X – 12
Which ordered pair is the solution to the system of equations?
Answers
Answer:
2 ordered pairs are solutions:
(1, -11) and (3, -9)
Step-by-step explanation:
The pairs (1, -11) and (3,-9) are the solution to the system of equations.
What are the roots of an equation?Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
If any coordinate or point is satisfy an equation then it will be solution of that equation.
Taking y = x - 12
If we keep all points one by one then we get to know that,
Point (1,11) and (3,-9) are satisfying;
(1, -11) ⇒ -11 = 1 - 12 = -11
(3,-9) ⇒ -9 = 3 - 12 = -9
Hence "The pairs (1, -11) and (3,-9) are the solution to the system of equations".

Kenji's town voted on a new speed limit. Of the votes received, 39 were in favor of the new speed limit and 13 were opposed. What percentage of the votes were in favor of the new speed limit?
Ik, I'm asking a lot of these but I HATE mathhhhh
Answers
Answer:
75%
Step-by-step explanation:
You need to find the total number of votes first. Just add 13 and 39 which would equal 52.
Then divide the number of people in favour by the total number of voters and multiply by a 100 to find the percentage.
39 + 13 = 52
39/52 = 0.75
0.75 x 100 = 75.0

The ratio of tagged fish to untagged fish was 2 to 9. Ninety fish were tagged. How many fish were untagged
Answers
Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405

Someone please help me state all the possible names for the figure
Please help this is geometry I would really appreciate it!!
Answers
Answer:
B.
Step-by-step explanation:
To answer, lets look at the definitions of each name.
First, a quadrilateral. A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices, so it basically just has 4 sides, which this figure has, so this figure is a quadrilateral.
Next, a parallelogram. A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. So as long as a figure has 4 sides and at least 2 opposite sides that will never collide, it is a parallelogram. Because our figure has 4 sides and each pair of opposite sides is parallel, this figure is a parallelogram.
Last, a rectangle. A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. So, as long as there are 4 sides and 4 right angles, and 2 of the opposite sides are longer than the other set of opposite sides, it is a rectangle, and this figure fills all the requirements.
So, since the figure is a quadrilateral, a parallelogram, and a rectangle, the answer is B.

Which of the following equations could you solve by first adding six and then dividing by negative three?
6 - 3 x = -9
+ 6 = -9
-3 x - 6 = -9
3 x - 6 = -9
Answers
Answer:
-3x - 6 = -9 (The third answer)
Step-by-step explanation:
When solving for x, you have to undo each operation. When solving -3x - 6 = -9, you have to undo the -6 first. To do this, add 6 to both sides. Then, you must undo the -3x. To do this, divide by -3 from both sides.
9 A rectangle of perimeter 42 cm is
pcm long and q cm broad. If the
difference between the length and
breadth is 9 cm. find
pand q
the area of the rectangle
Answers
Answer:
The correct answer is = p = 15 and q = 6.
Step-by-step explanation:
Given:
Perimeter of rectangle = 42 cm
p - q = 9 cm
length = p
width = q
we know:
Perimeter of rectangle= 2(l+w)
solution:
42 = 2(P+q)
21= p+q
Difference of p and q = 9 cm.
Then, P+q=21 .... 1
P-q=9 ....2
Adding both 1 and 2
2P = 30
P= 15cm and
q = 15-9
= 6cm

Answers
The Median is $34.99.
It is required to find the median.
What is a median?The median is the middle value in a set of data. First, organize and order the data from smallest to largest. The median is the value separating the higher half from the lower half of a data sample.
Given:
The data below :
$19.99, $8.99, $35.99, $49.99, $49.99, $39.99, $99.99, $79.99, $35.99, $19.99, $49.99, $29.99, $49.99, $59.99, $35.99, $49.99, $19.99, $8.99, $29.99, $35.99
The middle numbers are $19.99 and $49.99, add them both and divide by 2 we have,
Median
=$19.99 +$49.99/2
= $34.99.
Therefore, the Median is $34.99.
