Answer:
Infinite number of solutions
Step-by-step explanation:
when you solve for V, you notice that the term in "v" goes away, and you end up with a true statement:
2 = 2
This is a true statement no matter what values the variable V has, so it is true for all possible (infinite) values of "v".

Same sides add and keep. Different signs subtract. Keep the sign of the higher number.
The graph shows the soulution
Answer:
B. (3, -2)
Step-by-step explanation:
The solution of the system of the equations given, can be determined using the graph. The coordinate of the point where the two lines of both equations intersect is the solution.
Both lines intersect at x = 3, when y = -2.
Therefore, the solution would be (3, -2).

Answer:
1[tex]\frac{11}{16}[/tex]
Step-by-step explanation:
When multiplying mixed numbers, you would want to turn them into improper fractions first before evaluating.
[tex]\frac{3}{4}[/tex] × 2[tex]\frac{1}{4}[/tex] = [tex]\frac{3}{4}[/tex] × [tex]\frac{9}{4}[/tex]
Now you can just directly multiply the fractions (denominators with denominators and numerators with numerators)
[tex]\frac{3}{4}[/tex] × [tex]\frac{9}{4}[/tex] = [tex]\frac{27}{16}[/tex]
You know that is still an improper fraction, so you need to turn it back to a mixed number.
[tex]\frac{27}{16}[/tex] = 1[tex]\frac{11}{16}[/tex]

I don't really know but I believe it is:
Rounded to the nearest thousandth, the conditional relative frequency that an eleventh grader likes tennis is 69%.
ROunded to the nearest thousandth, the conditional relative frequency that a twelfth grader likes tennis is 51%.
Since 51% is less than 69%, a greater percent of eleventh grader like tennis.
The price of a video game was reduced from 60 to 45 . By what percentage was the price of the video game reduced
Answer:
The price was reduced from $60 to $45 - So the price was reduced by $15. $15 is what percent of the original price of $60? Percentages can be expressed as fractions or decimals. For example, 30% is the same as 0.30 or 30/100.

Answer:
(x, y, z) = (-8 2/7, -10, -7 3/7)
Step-by-step explanation:
A graphing calculator or matrix solver can find the solution easily. It is ...
(x, y, z) = (-8 2/7, -10, -7 3/7)
__
You can find y by subtracting the second equation from the third:
(2x -y +z) -(2x -3y +z) = (-14) -(6)
2y = -20
y = -10
Putting this value into the first equation and either of the others gives ...
x -3z = 14
2x +z = -24
Subtracting twice the first of these from the second gives ...
(2x +z) -2(x -3z) = (-24) -2(14)
7z = -52
z = -52/7 = -7 3/7
x = 14 +3(-7 3/7) = -8 2/7
So, the solution is (x, y, z) = (-8 2/7, -10, -7 3/7).

Find the value of x and y. Show all your work neat and
in order.
Answer:
x = 21°
y = 29°
Step-by-step explanation:
a) Solving for x
Note that:
(3x - 3)° and 60° are Alternate interior angles, and alternate interior angles are equal to each other, hence:
3x - 3 = 60° (Alternate interior angles)
Add 3 to both sides
3x - 3 +3 = 60 + 3
3x = 63°
x = 63°/3
x = 21°
b) Solving for y
Notes that:
(3x - 3)° and (4y + 4)° are Consecutive interior angles and the sum consecutive interior angles is 180°
3x - 3 + 4y + 4 = 180°
3x + 4y - 3 + 4 = 180°
3x + 4y + 1 = 180°
Note that x = 21
Hence
3(21) + 4y + 1 = 180°
63 + 1 + 4y = 180°
64 + 4y = 180°
Subtract 64 from both sides
64 - 64 + 4y = 180° - 64
4y = 116°
y = 116/4
y => 29°
A shoe store costs 1800 dollars a month to operate. The average wholesale cost of each pair of shoes is 25 dollars, and the average price of each pair of shoes is 65 dollars. How many pairs of shoes must the store sell each month to break even?
Answer: 45
Step-by-step explanation:
The store has to sell
45
pairs of shoes.
Explanation:
The store has a base cost of
$
1800
, the cost per pair of shoes is
$
25
. Each pair of shoes is sold for
$
65
, therefore the profit per pair of shoes is
$
65
−
$
25
=
$
40
The formula for calculating the amount that needs to be sold would look like this;
40
x
=
1800
To determine the value of
x
, we take this formula;
x
=
1800
40
x
=
45
Therefore, the store needs to sell
45
pairs of shoes to break even.
