Solve the simultaneous equation:
2x+3y=13
X+2y=9
Answer:
2x + 3y = 13
4x - y = -2
In the second equation, subtract 4x from both sides.
-y = -2 - 4x
Divide both sides by -1.
y = 2 + 4x
Put this into the first equation in place of y.
2x + 3(2 + 4x) = 13
Multiply everything in the parenthesis by 3.
2x + 6 + 12x = 13
Combine like terms.
14x + 6 = 13
Subtract 6 from both sides.
14x = 7
Divide 14 on both sides.
x = 7 / 14
x = 0.5
Put this into the second equation in place of x.
4(0.5) - y = -2
2 - y = -2
Subtract 2 from both sides.
-y = -4
Divide both sides by -1.
y = 4
So x = 0.5 and y = 4.

which is grater .856 or .8561
Answer: .8561
Step-by-step explanation: If you make them the same number by adding a 0 to .856 it would look like
.8561
.8560
Answer:
I think it would be .856
Step-by-step explanation:
0.5 is greater than 0.05. There are many ways to deduce this:
The more the # of zeroes after the decimal point the smaller the number is. Suppose there are x number of extra zeroes after the decimal point in number a than number b. Then, b is 10^x times larger than a.
Multiply both numbers by 100. we can see 0.5*100 (=50) > 0.05*100 (=5)
Fractionalize both numbers, we get 0.5=(5/10) but 0.05=(5/100). This makes 0.05<0.5

Solve the system of equations -3x+7y=-18 and 4x-4y=8 by combining the equations.
Explaining Is Required
Answer:
[tex]\huge \colorbox{red}{(x,y)=(-1,-3)}[/tex]
Step-by-step explanation:
multiply first equation by 4 and second by 3 respectively:
[tex] \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}[/tex]
combine the equations:
[tex] \underline{ \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}} \\ \displaystyle16y = - 48[/tex]
divide both sides by -48:
[tex] \displaystyle \: \frac{16y}{16} = \frac{ - 48}{16} \\ y = - 3[/tex]
substitute the value of y to the second equation
[tex] \displaystyle \: 4x - 4. - 3 = 8[/tex]
simplify multiplication:
[tex] \displaystyle \: 4x + 12 = 8[/tex]
cancel 12 from both sides:
[tex] \displaystyle \: 4x = - 4[/tex]
divide both sides by 4
[tex] \displaystyle \: \frac{4x}{4} = \frac{ - 4}{4} \\ x = - 1[/tex]
therefore our solution is
[tex]\displaystyle (x,y)=(-1,-3)[/tex]
Answer:
Solution given:
-3x+7y=-18
3x-7y=18.................[1]
4x-4y=8
4(x-y)=8
x-y=[tex] \frac{8}{2} [/tex]
x-y=2..........….........[2]
multiplying equation 2 by 3 and subracting equation 1 and 2,we get
[tex]3x-7y - 3x + 3y = 18 - 6[/tex]
-4y=12
y=[tex] \frac{12}{ - 4} [/tex]=-3
substituting value of y in equation 2,we get
x-(-3)=2
x=2-3
x=-1

x=-1
y=-3

Take a factor out of the square root:
Answer:
[tex]-y\sqrt{3}[/tex]
Step-by-step explanation:
Under the radical there is a perfect square, one can take the perfect square out, and write it by its square root. The result of taking the principal square root is always positive, but it is given that the perfect square factor is negative, thus, one must multiply the square root by the negative sign to ensure that the result is positive.

Al principio Eduardo y Adrián tenían el mismo número de dulces. Eduardo le dio a Adrián la mitad de los dulces que tenía. Después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces. ¿Cuántos dulces tenía Eduardo al final? *
Answer:
Al final, Eduardo tenía 20 dulces.
Step-by-step explanation:
Dado que al principio Eduardo y Adrián tenían el mismo número de dulces, y Eduardo le dio a Adrián la mitad de los dulces que tenía, y después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces, para determinar cuántos dulces tenía Eduardo al final se debe realizar el siguiente cálculo:
Eduardo 1X = Adrián 1X
Eduardo 0.5X = Adrián 1.5X
Eduardo 1.25X = Adrián 0.75X
0.75 X = 12
X = 12 / 0.75
X = 16
1.25 X = 16 x 1.25 = 20
Así, al final, Eduardo tenía 20 dulces.

What is the volume of a hemisphere with a radius of 60.7 m, rounded to the nearest tenth of a cubic meter?
Answer:
468408.4m
Step-by-step explanation:
The guy above knows
The volume of a hemisphere with a radius of 60.7 m is 468170.95 cubic meter.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, a radius of a hemisphere is 60.7 m.
Half of a sphere, or a hemisphere, is a three-dimensional (3D) shape. The form we obtain when a sphere is split by a plane going through its centre is known as a hemisphere. A hemisphere has one flat circular base and a curving surface. The quantity of unit cubes that can fit inside a hemisphere is known as its volume.
We know that, the volume of a hemisphere is (2/3)πr³.
Here, volume is 2/3 ×3.14×60.7³
= 2/3 ×3.14×223648.543
= 468170.95 cubic meter
Therefore, the volume is 468170.95 cubic meter.

A waffle cone has a volume of 31.254 cubic centimeters and a radius of
2.5 centimeters. What is the approximate height of the cone?
Answer:
4.78 cm
Step-by-step explanation:
The formula for the volume of a cone of radius r and height h is
V = (1/3)πr²h. Here, V = 31.254 cm³ and r = 2.5 cm.
We begin by solving V = (1/3)πr²h for the unknown height, h:
31.254 cm³ 3(31.254 cm³) 93.762 cm³
h = ------------------------ = -------------------------- = -------------------- ≈ 4.78 cm
(1/3)πr² π(2.5 cm)² 19.635 cm²
A mad scientist is trying to turn herself into a superhero in her lab at point B. There is an explosion and
anyone within a radius of 8 miles from the lab turns into a superhero. Unfortunately, anyone between 8 and
10 miles from the blast turns into an evil villain. If the population is evenly distributed over the total area,
are there more evil villains or more superheroes?
Answer:
superheros
Step-by-step explanation:
area of the 8 milrs- 201.06sq miles
area of 10 miles- 314.16sq miles
subtract the 210.06 from 314.16, 104.1
so, 210.06 square miles of heros, 104.1 square miles of villians
