The value of x and y using the elimination approach on the equations will be 3.45 and 2.81 respectively.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

Given the set of equations,

3x + 2y=16

2x +5y=21

Multiply by 2 to the first equation and by 3 to the second equation.

Fist becomes ⇒

6x + 4y = 32

Second become ⇒

6x + 15y = 63

By subtracting second - first

11y = 31

y = 2.818181...

By substitution,

6x + 4(2.81) = 32

x = 3.454545..

Hence "The value of x and y using the elimination approach on the equations will be 3.45 and 2.81 respectively".

Answer:

Step-by-step explanation:

the mean height, remember is the average

62+62+59+61+59+70+59+62=494/8=61.75

median is the middle value, so we will write the numbers in order

59,59,59,61,62,62,62,70

we have an even number so we add the middle numbers and divide by 2,

the median=61+62=123/2=61.50  

mode is the number that occurs most often : 62 and 59

Answer:

DEF can have possible side lengths of 28, 16, 20.8

Step-by-step explanation:

Triangle Similarity

If the three sides of two triangles have the same proportion, the triangles are similar (SSS theorem).

Triangle ABC has side lengths of 14, 8, and 10.4.

Any other triangle whose side lengths are the same lengths of ABC multiplied by a constant scale factor is similar to ABC.

For example, select scale factor 2. Thus, the triangle of side lengths 2*14=28, 2*8=16, and 2*10.4=20.8 is similar:

DEF can have possible side lengths of 28, 16, 20.8

Any other scale factor will do.

Step-by-step explanation:

We will start by writing the following ratio

miles:gas

1200:60

This means that we have

x:1

divide 1200 by 60 to get x

I get

x=20

Answer:

20 miles per gallon.

Step-by-step explanation:

You have to divide 1,200 by 60. Then you will be left with 20 miles/gallon

Step-by-step explanation:

There are missing details, which is why its solution is as follows:

When an angle bisector points so, its two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions. In such a single point, calling its incentives, follow three-angle engineers are required of its three triangle angles.

Answer:

y=3

Step-by-step explanation:

First, let's find the slope (m) of the line, which we do with the equation (y2-y1)/(x2-x1)

the given points are (9,3) and (7,3)

we can label the points:

x1=9

y1=3

x2=7

y2=3

now substitute into the equation

m=(3-3)/(7-9)

m=0/-2

m=0

the slope is 0.

Now, use slope-point form, which is y-y1=m(x-x1)

substitute using the given numbers

y-3=0(x-9)

multiply

y-3=0

add 3 to both sides

y=3

the equation is y=3

Answer:

B. f(x) = x² + 10x + 17

Step-by-step explanation:

Given:

f(x) = (x + 5)² - 8

Required:

Write in standard form

SOLUTION:

f(x) = (x + 5)² - 8

Expand (x + 5)²

f(x) = (x + 5)(x + 5) - 8

f(x) = x(x + 5) +5(x + 5) - 8

f(x) = x² + 5x + 5x + 25 - 8

Add like terms

f(x) = x² + 10x + 17

Step-by-step explanation:

To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line. If the inequality is strict ( < or > ), graph a dashed line.

Answer:

98 degrees

Step-by-step explanation:

Since angle LON is a straight angle, that means its measure is 180 degrees. So, the two angles that make up angle LON add up to 180. You can create the following equation:

(3x + 89) + (8x + 58) = 180

Then, add like terms.

3x + 8x = 11x

89 + 58 = 147

11x + 147 = 180

Subtract 147 from both sides.

11x = 180 - 147

Add like terms.

11x = 33

Now, divide by 11 on both sides.

x = 3

Since we now have the value of x, we can plug it into the equation to find angle MON:

MON = 3x + 89

Substitute 3 for x

MON = 3(3) + 89

MON = 9 + 89

MON = 98

an algebraic expression that has a term with a coefficient of 9 is

Step-by-step explanation:

a) How much-water will be in the water storage facility in 25 minutes?

Since the city water workers begin filling it at a rate of 500 gallons per minute, in 25 minutes they'll have filled:

= 500 × 25

= 12500 gallons

It immediately begins sending some of its water into the city's water pipes at a rate of 150 gallons per minutes. In 25 minutes, they'll have sent:

= 150 × 25

= 3750 gallons

Amount that'll be left in the tank will be:

= 12500 - 3750

= 8750 gallons

b. Write an equation to find the number of gallons,y,in the storage facility after x minutes. This will be:

y = (500 × x ) - (150 × x)

y = 500x - 150x

y = 350x

Answer:

1/6

Step-by-step

When 1/3 divided by 2 gives 1/6.

fraction, In arithmetic, a number expressed as a quotient, in which a numerator is divided by a denominator.

In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator. In a proper fraction, the numerator is less than the denominator.

If we divide 1/3 by 2, which is not possible

Fraction also multiplication only.

To make the division into multiplication we have to reciprocal the number on the right side of the division

So,

1/3÷2

=1/3*1/2

= 1/6

Hence,  1/3 divided by 2 in fraction form gives 1/6.

Step-by-step explanation:

The given equation is :

[tex]h=\dfrac{l}{l-2k}[/tex] ....(1)

We need to find the value of k.

Cross multiplying equation (1)

[tex]h(l-2k)=l\\\\hl-2hk=l\\\\hl-l=2hk\\\\k=\dfrac{l(h-1)}{2h}[/tex]

So, the value of k is equal to [tex]\dfrac{l(h-1)}{2h}[/tex].
