Answer:

first number is 4

second number is 0

Step-by-step explanation:

y = 1st number

x = 2nd number

system of equations:

5y + 4x = 20

4y + 2x = 16

I multiplied the second equation by -2 to eliminate the 'x-values'

-2(4y + 2x = 16)  =                 -8y - 4x = -32

now add to 1st equation:     5y + 4x = 20

                                              -3y = -12

y = 4

solve for 'x':

5(4) + 4x = 20

20 + 4x = 20

4x = 0

x = 0

Answer:

A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km. More precisely, one light-year is equal to 9,500,000,000,000 kilometers.

step 4. the translation can be written (x + 7, y - 2)

step 5. the pre image was located in quadrant II.

Answer:

x=9

JKL = 108 degrees

KLJ = 27 degrees

LJK = 45 degrees

Step-by-step explanation:

Add all the values of the triangle angles together to get 20. Then divide 180 by  20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).

JKL = 12x = 12(9) = 108

KLJ = 3x = 3(9) = 27

LJK = 5x = 5(9) = 45

Answer:

27

Step-by-step explanation:

200 ÷ 7 = 27

Answer:

6 1/3 Is a mixed fraction

Given:

3450 yen is divided in the ratios 2:6:7.

To find:

The difference between the largest share and the smallest share.

Solution:

3450 yen is divided in the ratios 2:6:7. Let the shares are 2x, 6x and 7x.

[tex]2x+6x+7x=3450[/tex]

[tex]15x=3450[/tex]

[tex]x=\dfrac{3450}{15}[/tex]

[tex]x=230[/tex]

Now,

First share is

[tex]2(230)=460[/tex]

Second share is

[tex]6(230)=1380[/tex]

Third share is

[tex]7(230)=1610[/tex]

Here the largest share is 1610 and the smallest share is 460. So, the difference between the largest share and the smallest share is

[tex]1610-460=1150[/tex]

Therefore, the difference between the largest share and the smallest share is 1150 yen.

Step-by-step explanation:

factor the coefficients into primes

18 = 3 * 3 * 2

42 = 3* 2 * 7

- 12 = - 2 * 2 * 3

The primes that are underlined are 2 * 3 which is 6

The primes not in the brackets are what is inside the brackets.

The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30

Where 27w represents the cost of w walks.

Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

Answer:

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Step-by-step explanation:

Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:

[tex]20 = a\cdot b^{0}[/tex] (1)

[tex]720 = a\cdot b^{2}[/tex] (2)

By dividing (2) by (1), we obtain the value for [tex]b[/tex]:

[tex]\frac{720}{20} = b^{2}[/tex]

[tex]b = \sqrt{\frac{720}{20} }[/tex]

[tex]b = 6[/tex]

And the value for [tex]a[/tex] is found by (1):

[tex]a = 20[/tex]

The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Step-by-step explanation:

Gwen had 27 bites altogether. She had 15 on her legs and 12 on her arm

An equation shows the relationship between two or more numbers and variables.

Let x represent the mosquito bites on leg and y represent the bites on arms.  She counted 5 mosquito bites on her legs for every 4 bites on her arms, hence:

x/y = 5/4

4x = 5y

4x - 5y = 0     (1)

Also,  Gwen had 3 more mosquito bites on her legs than on her arms, hence:

x = y + 3    (2)

From both equations:

x = 15, y = 12

x + y = 15 + 12 = 27

Gwen had 27 bites altogether

Given:

One midsegment of an equilateral triangle.

To find:

The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.

Solution:

All sides of an equilateral triangle are same.

Let a be the each side of the equilateral triangle.

Length of the midsegment is equal to the half of the non included side or third side.

[tex]Midsegment=\dfrac{a}{2}[/tex]

The sum of two side is

[tex]a+a=2a[/tex]

Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is

[tex]\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}[/tex]

[tex]\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}[/tex]

[tex]\text{Required ratio}=\dfrac{a}{4a}[/tex]

[tex]\text{Required ratio}=\dfrac{1}{4}[/tex]

[tex]\text{Required ratio}=1:4[/tex]

Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.
