Simplify each complex fraction.
2/x + y / 3
The simplification of the given complex fraction 2/(x +y/3) is
6/(3x + y).
Accoring to the given question.
We have a complex fraction.
2/(x +y/3)
As we know that, complex fraction is a rational expression that has a fraction in its numerator, denominator or both.
For example: (2/3)/(4/6)
So, the above complex fraction can be simplified by
(2/3) × (6/4)
= (2/3) × (3/2)
= 1
Thereofore, the siplification of the complex fraction 2/(x +y/3) is given by
[tex]\frac{2}{x + \frac{y}{3} }[/tex]
= [tex]\frac{2}{\frac{3x+y}{3} }[/tex]
= 2(3)/(3x + y)
= 6/(3x + y)
Hence, the simplification of the given complex fraction 2/(x +y/3) is

Suppose you write and solve an equation to determine the amount of money m you have in your bank account after several weeks. You find that m=-36 . What does this solution mean?
Answer:
From the Soldier's point of view, the American Civil War was not a continuous battle. Instead, it was long monotonous marches and long residency in camps punctuated by the terror and chaos of combat. When winter set in and the campaigning season came to a close, most Soldiers counted on a long, cold stay in a winter camp. The four log cabins at the center of the Army Heritage Trail represent the types of buildings which Soldiers in both the Union and the Confederate Armies spent the long dreary months of winter. The cabins are modeled after images from the USAHEC collection, including the Army of the Potomac's winter camp at Brandy Station and the Confederate camp at Centerville
Leah walks 13 miles in 6 hours .lee walks 5 miles in 3 hours .Hercules walks 36 miles in 8 hours which Person had the fastest pace
Answer: Hercules has the fastest pace
Step-by-step explanation:
L=Leah. l=lee. H=Hercules
**Since the speeds are in fractions, make the denominators the same.
L=13/6
l=5/3
l=(5*2)/(3*2)
l=10/6
H=36/8
H=(36*6/8)/(8*6/8)
H=(216/8)/(48/8)
H=27/6
27/6 > 13/6 > 10/6
H>L>l
Hercules has the fastest pace
Express each fraction as a decimal to the nearest hundredth.
43/46
43/49= 0.93
To express each fraction into its decimal we need to bring 100 at the denominator.
Fraction = numerator\denominator
For example :
1> 4\5
= 4*20\ 5* 20
= 80\ 100
= 0.80
2> 1\4
= 1 *20\ 4 *20
= 20\ 100
= 0.20
3> 49/50
= 49*2/50*2
= 98/100
=0.98
There are some numbers where it is not possible to make the denominator 100
So by the process of division method, we can convert the fraction into decimal form

Find the area of the polygon.
The area of the polygon is what?
Answer:
Area = 792 m
Step-by-step explanation:
You can cut the polygon into 2 rectangles.
Subtracting 18 from 60 can give you the length of rectangle A, so 42 will be the new length for rectangle A.
Multiply 6 and 42 to get 252 for the area of rectangle A.
Multiply 18 and 30 to get 540 for the area of rectangle B.
(You multiply to find the area.)
Lastly you add both areas, 252 + 540, and the final result is:
Area = 792 m
Two lines intersect at point P. If the measures of a pair of vertical angles are (2x-7)° and, (x+3)° determine x and the measures of the other two angles?
Answer:
x = 10
One angle is 13 and the other angle is 13
Step-by-step explanation:
Vertical angles have the same measurement, so set the angles equal to each other and solve for x.
2x - 7 = x + 3 Subtract x from both sides of the equation
x - 7 = 3 Add 7 to both sides of the equation
x = 10 Now use this to solve for both angles
2(10) - 7 =
20 - 7 =

I need to find out the quadrilateral of 78° k,L,N,M
Answer: ∠L = 102°
∠N = 78°
Step-by-step explanation:
Quadrilaterals can be classified into Parallelograms, Squares, Rectangles, and Rhombuses. Square, Rectangle, and Rhombus are also Parallelograms.
A quadrilateral is called a parallelogram, if both pairs of its opposite sides are parallel. AB ∥ DC and AD ∥ BC. So, ABCD is a parallelogram. A parallelogram having all sides equal, is called a rhombus.
Given data,
In □KLMN, side LM ∥ side KN, side KL ≅ side NM If ∠K = 78°
then find the measure of ∠L, and ∠N
side LM∥ side KN
Interior angles on the same side of the transversal are supplementary.
∠K + ∠L = 180°
78° + ∠L = 180°
∠L = 180° - 78°
∠L = 102°
Construction:
Draw LP ∥ MN
So, LM ∥ KN and LP ∥ MN
PLMN is a parallelogram
MN ≅ LP
Now MN = LP and MN = KL
LP = KL
∠LKP = ∠LPK = 78°
LP ∥ MN so,
∠MNP = ∠LPK = 78° (corresponding angles are equal)
∠L = 102°
∠N = 78°
Therefore,
∠L = 102°
∠N = 78°.

How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given the condition making a graph as shown below,
Now in ΔAOC and ΔBOC, the angle x is the same.
Distance AO = BO and CO is common side.
So both triangles will be congruent.
Since all corresponding side of two congruent triangles is the same.
So,
AC = BC hence C will be the midpoint of A and B.

The length of an inscribed angle is half the length of the central angle. The circumscribed angle's measure is 180 degrees less the central angle's measure.

Simplify by combining like terms. 5 v-3(2-v)
The simplification by combining like terms of 5v-3(2 -v) is 8v - 6.
According to the given question.
We have an expression5v - 3(2 - v).
As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same. when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.
Since, we have to combine the like terms of the given expression
5v - 3(2 - v).
Here 5v, and 3v both are the like terms.
So, we add coeffcients of v to simplify the given expression.
Therefore, the simplification of 5v -3 (2 -v ) is given by
5v - 3(2 - v)
= 5v - 6 + 3v
= 8v - 6
Hence, the simplification by combining like terms of 5v - 3(2 - v) is 8v - 6.

19. The substitution method was used, as writing x as a function of y in the given equation was quite straight forward, as was replacing into the second equation to find y.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
For item 17, the system is:
3x + 2y = 17.4x - 2y = 4.Adding the equations, we can eliminate y and solve for x, hence:
7x = 21
x = 3.
Then the solution for y is given as follows:
3x + 2y = 17
3(3) + 2y = 17
2y = 8
y = 4.
For item 18, the variables are given as follows:
Variable x: number of level I engineers.Variable y: number of level II engineers.The company has 8 engineers, hence:
x + y = 8 -> x = 8 - y.
The company can afford to pay a total of $472,000 to the engineers, hence, considering the salaries(in thousands of dollars) of each:
56x + 68y = 472.
We want to solve for y, hence, since x = 8 - y:
56x + 68y = 472.
56(8 - y) + 68y = 472.
12y = 24.
y = 2.

What is meant by cross multiplication?In cross-multiplication, the numerator of the first fraction is multiplied by the denominator of the second fraction, and the numerator of the second fraction is multiplied by the denominator of the first fraction.
Denominators are removed during cross multiplication. It's employed to make comparisons fraction sizes, solve proportional and percentage problems.A absent value or variable is common in proportion problems. After removing the denominators with cross multiplication, algebra skills are employed to solve again for missing variable. Percentage problems are solved in the same way that proportion problems are.Now, the given equation is as follows;
y/y+1 = 2/3
Cross-multiplying the values;
3y = 2(y + 1)
3 y = 2y + 2
Bring the variable on the single side and constants on the other.
3y - 2y = 2
y = 2
Therefore, the solution of the given equation y/y+1 = 2/3 is computed as (y = 2).
