Read the following situation:
There are 13 animals in the barn. Some are chickens and some are pigs. There are 40 legs in all. How many of each animal are there?
When setting up the system, what could the variables represent? Select all that apply.
Total number of chicken legs
Total number of pigs
How long until the number of pigs and chickens are equal.
How many animals in the barn
Total number of pig legs
Total number of chickens
Where the lines cross
Answer:
Hi, let's turn the word problem into a set of equations:
Let's say that x = # of chickens, and y = # of pigs
If there are 13 animals altogether, that means that
x + y = 13
If there are 40 legs together, we know that chickens have 2 legs, while pigs have 4, so the total number of legs would be:
2x + 4y = 40
We now have two different equations, with the same two variables, so we can rearrange and substitute one equation into the other to solve. We can rearrange the first equation as:
x + y = 13
x = 13 - y
Let's plug this expression for "x" into the second equation:
2(13-y) + 4y = 40
Now we have an equation with only one variable, so we can use algebra to solve for y:
26 - 2y + 4y = 40
2y = 14
y = 7, there must be 7 pigs.
From the first equation that we rearranged,
x = 13 - y
Now that we know the numerical value of "y", we can plug that in:
x = 13 - 7
x = 6, there must be 6 chickens
Drag each equation to show if it could be a correct first step to solving the equation 3(6+x)=24
Use the distributive property.
3(6 + x) = 24
18 + 3x = 24
3x = 6
x = 2
Answer:
x=2
Step-by-step explanation:
3(6+x)=24
Divide both sides by 3.
6+x=24/3
Divide 24 by 3 to get 8.
6+x=8
Subtract 6 from both sides.
x=8−6
Subtract 6 from 8 to get 2.
x=2
Slope intercept form of 4x+4y=-32
Answer:
y = - x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 4y = - 32 ( subtract 4x from both sides )
4y = - 4x - 32 ( divide all terms by 4 )
y = - x - 8 ← in slope- intercept form
Answer:
x+y=-8
Step-by-step explanation:
-32=4x+4y
-4y=4x+32
y=(4x+32)/-4
y=-x-8
x+y=-8
Now comparing to slope intercept form
y=mx+c,we get
slope =1
y intercept =1
y=-8

Answer:
h(x) = - (x + 5)³
Step-by-step explanation:
From the graph attached,
Function 'h' is the transformed form of function 'g',
If function 'g' is shifted by k units to the left, the new function 'h' will be,
h(x) = g(x + k)
As shown in the graph,
Function 'g' has been shifted by 6 units to the left,
h(x) = g(x + 6)
h(x) = - [(x + 6) - 1]³
h(x) = - (x + 5)³

The volume (V) of a cylinder can be found using the formula V = (pi)r^2h, where r is the radius and h is the height. A cylinder has a diameter of
2 inches. It is filled with water to a the height of 4 inches. The water is then transferred to a new cylinder with a diameter of 4 inches.
What is the height of the water in the new cylinder?
Answer:
1 inch
Step-by-step explanation:
volume of first cylinder = volume of second cylinder because it never changes it stays the same
volume of first cylinder = (pi) (1)^2 (4) = 4pi
height of second cylinder: 4pi = (pi) (2)^2 h
pi would cancel so you are left with 4=4h
where height of second cylinder would be 1 in

given JM=27, ml=16, jl=46, nk=15, KLM= 48, JkM=78, MJL=22, find each missing value.
Answer:
KL = 27
JK = 16
MK = 30
NL = 23
m∠JKL = 132°
m∠KLJ = 22°
m∠KMJ = 54°
m∠KJL = 26°
Step-by-step explanation:
The given parameters of the quadrilateral JKLM are;
JM = 27, ML = 16, JL = 46, NK = 15, KLM = 48, JKM = 78, MJL = 22
Taking the sides as parallel, we have that quadrilateral JKLM is a parallelogram
Therefore;
KL = JM = 27
JK = ML = 16
m∠KLJ = m∠MJL = 22°
MN = NK = 15
MK = MN + NK = 15 + 15 = 30
NL = JL/2 = 46/2 = 23
m∠KJM = m∠KLM = 48°
m∠KJL = m∠KLM - m∠MJL = 48° - 22° = 26°
m∠KML = m∠JKM = 78°
m∠MKL = 180° - m∠KML - m∠KLM = 180° - 78° - 48° = 54°
m∠MKL = 54°
m∠JKL = m∠JKM + m∠MKL = 78° + 54° = 132°
m∠KMJ = m∠MKL = 54°
Applying the properties of a parallelogram, the missing values are:
KL = 27; JK = 16; MK = 30; NL = 23
m∠JKL = 132°; m∠KLJ = 22°; m∠KMJ = 54°; m∠KJL = 26°
What are the Properties of a Parallelogram?Diagonals bisects each other into equal parts.Parallelograms have two pairs of opposite sides that are parallel and congruent to each other.Angles opposite each other in a parallelogram are equal.Consecutive angles in a parallelogram are supplementary.Applying the properties of a parallelogram, we will find the given measures as follows:
KL = JM (congruent sides)
KL = 27
JK = ML (congruent sides)
JK = 16
MK = 2(NK)
Substitute
MK = 2(15)
MK = 30
NL = 1/2(JL)
NL = 1/2(46)
NL = 23
m∠JKL = 180 - m∠KLM (supplementary angles)
m∠JKL = 180 - 48
m∠JKL = 132°
m∠KLJ = m∠MJL (congruent angles)
m∠KLJ = 22°
m∠KMJ = m∠MKL (congruent angles)
m∠MKL = 180° - 78° - 48° = 54°
m∠KMJ = m∠MKL = 54°
m∠KMJ = 54°
m∠KJL = 48° - 22°
m∠KJL = 26°

The answer is Zero.

Adding a negitive 5 to a positive 5 cancels out
Answer:

Step-by-step explanation:
It's a negative five, meaning that if you are adding it, the number will still go back.
You made $5, but you're in debt of $5. So even though it is supposed to go up, it goes down back to 0 due to the debt, which is the negative.

What is the principal which would amount to $6900 in 3 years at 5% simple interest per annum?
Answer:
$6000
Step-by-step explanation:
accumulated amount = A = PI
A = $6900
Let P = x
6900 - I = x
I = (x)(0.05)(3yrs) = 0.15x
6900 - 0.15x = x
Add
6900 = 1.15x
Divide, solve for x
x = 6000

A bike trail is drawn on a coordinate system. Each end of the trail is an x-intercept. The height of the trail is modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers. How many meters is the horizontal distance of the trail?
Answer:
4metres
Step-by-step explanation:
Given the height of the trail modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers
The horizontal distance occurs at the x intercept i.e at h(x) = 0
Substitute
0 = -0.1x^2 - 0.3x +2.8 ,
Multiply through by -10
0 = x^2 + 3x - 28
x^2 + 3x - 28 = 0
Factorize
x^2 + 7x - 4x - 28 = 0
x(x+7) - 4 (x+7) = 0
(x-4)(x+7) = 0
x-4 = 0 and x+7 = 0
x = 4 and -7
Since the danced cannot be negative, hence the horizontal distance of the trail is 4m
