Im pretty sure its 2 but not exactly
Answer:
Step-by-step explanation:
-x - 5y = -29 + 4y - y + 5
Add x to both sides
-x - 5y + x = -29 + 4y - y + 5 + x
-5y = 4y - y -29 +5 + x {Add the like terms}
-5y = 3y - 24 + x {subtract 3y form both sides}
-5y - 8y = 3y - 24 + x - 3y
-13y = x - 24
Divide both sides by (-13)
y = (x-24)/-13
y = -(x-24)/13

The equations 4 x minus 5 y = 5, 3 x + 10 y = 20, 4 x minus 5 y = negative 5, and 3 x + 10 y = negative 20 are shown on the graph below. On a coordinate plane, there are 4 lines. Green line goes through (0, 1) and (2.5, 3). Orange line goes through (0, negative 1) and (2.5, 1). Blue line goes through (0, 2) and (3.5, 1). Pink line goes through (0, negative 2) and (3.5, negative 3). Which system of equations has a solution of approximately (–2.7, –1.2)? 4 x minus 5 y = negative 5 and 3 x + 10 y = negative 20 4 x minus 5 y = 5 and 3 x + 10 y = 20 4 x minus 5 y = 5 and 3 x + 10 y = negative 20 4 x minus 5 y = negative 5 and 3 x + 10 y = 20
Answer:
4 x minus 5 y = negative 5 and 3 x + 10 y = negative 20
Step-by-step explanation:
The equations
4 x - 5 y = 5 (red)
3 x + 10 y = 20 (blue)
4 x - 5 y = -5 (green)
3 x + 10 y = -20 (purple)
are shown in the picture attached. As we can see there, the point (–2.7, –1.2) is on the intersection of the purple and green lines. Therefore is the solution of the system:
4 x - 5 y = -5
3 x + 10 y = -20

Compare the repeating decimals shown with their equivalent fractions. Describe the pattern. 0.111...(repeating)= 1/9, −0.555...(repeating)= −5/9, −1.222...(repeating)= −1 2/9, 5.888...(repeating)= 5 8/9
PLEASE SONEONE HELP ME!!!!!!!!!
Answer:
The pattern in decimal expressions is that the decimal numbers are repeated immediately after the decimal point.
The pattern in the equivalent fraction is that 9 is on all fractions
Step-by-step explanation:
All the cases (0.111..., −0.555..., −1.222... and 5.888...) are solving by the following procedure (only one example is shown):
x = 0.111111...
10x = 1.11111...
10x - x = 1.11111... - 0.111111...
9x = 1
x = 1/9
which is equivalent to express the decimal part as the tenth divided by 9. Then:
−0.555...= −5/9,
−1.222...(repeating)= −1 2/9,
5.888...(repeating)= 5 8/9
Can someone help me I was doing good and then I got stuck on this question what I can’t figure out is how you get the voltage when you only have the watt and resistance .
A 60.0 Watt lightbulb has an operating resistance of 220 Ω.
Calculate the operating voltage of this lightbulb.
Answer:
114.89 V
Step-by-step explanation:
Watts are a measure of power, and there is an equation that relates power, voltage, and resistance. It goes like this:
P=(V^2)/R
Now to find the voltage you want to solve for V
PR = V^2
V = [tex]\sqrt{PR}[/tex]
Now substitute your numbers into the equation and you get your answer
V = [tex]\sqrt{(60)(220)}[/tex]
V = [tex]\sqrt{13200}[/tex]
V = 114.89 V
The object below is made of solid plastic. It is a cylinder with an indentation at the top
in the shape of a cone.
What is the volume to the nearest tenth of a cubic inch, of the plastic object?
Answer: 97.6 in3
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:
Volume of a cylinder: π (diameter /2) ^2 (height)
Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3
Volume of a cone = 1/3 π (diameter /2) ^2 (height)
V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3
Finally:
Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3
Feel free to ask for more if needed or if you did not understand something.
Find the measure of QPR.. I need full explanation please
Answer:
b) 42°
Step-by-step explanation:
When two triangles share the same base (in this case, side QR), one angle is half of the other one. In this case:
1/2*∠QPR = ∠QSR
From the picture,
∠QSR = 21°
Replacing into the equation and solving for ∠QPR:
∠QPR = 2*21° = 42°

IT IS A CLOCK PROBLEM
What is the angle between the hands at 4:41?
Answer:127.5∘
Step-by-step explanation:
The angle measure between any two consecutive numbers on a clock is 36012=30∘.
Call the "12" point on the clock the zero-degree point.
At 4:45, the minute hand is at the "9" - that is, at the 30×9=270∘ mark. The hour hand is three-fourths of the way from the "4" to the "5; that is,
30×434=142.5∘ mark.
Therefore, the angle between the hands is
270−142.5=127.5∘, the desired measure.

What is the name of the point that you use to define a parabola?
A. Vertex
B. Center
C. Focus
D. Directrix
sig
Answer:
C
Step-by-step explanation:
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
Focus is the name of the point that you use to define a parabola
What is Parabola?A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped
A parabola is a symmetrical U-shaped curve that can be defined as the set of all points that are equidistant to a fixed point (called the focus) and a fixed line (called the directrix).
The vertex is the point where the parabola changes direction and is located halfway between the focus and the directrix.
The center is a term used to refer to the midpoint of the line segment connecting the two foci of an ellipse or hyperbola, and is not relevant to a parabola.
Hence, Focus is the name of the point that you use to define a parabola

Question Help
The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playing field
is 312 yards, what are its dimensions?
The width is yards
Answer:
Width of field = 50 yards
Length of Yards = 106 yards
Step-by-step explanation:
Let the width of field be x yards
given that "The length of a new rectangular playing field is 6 yards longer than double the width"
Length of Yards= 2*width of field + 6 = 2x+6 yards
perimeter of the rectangular playing field = 312 yards
We know that perimeter of rectangle is given by 2(length + width ).
Since field is rectangular then
2(length + width ) = 312
2(x+2x+6) = 312
=> 3x+6 = 312/2 = 156
=> 3x = 156 - 6 = 150
=> x = 150/3 = 50
Thus,
Width of field is x = 50 yards
Length of Yards= 2x+6 yards = 2*50+6 yards = 106 yards
