Answer-  A,D,E

Step-by-step explanation:

A two column table with 5 rows. The first column, x, has the entries, negative 2, 0, 2, 4. The second column, y, has the entries, 6, 3.5, 1, negative 1.5.

Which equations represent the data in the table? Check all that apply.

y – 6 = y minus 6 equals StartFraction negative 5 Over 4 EndFraction left-parenthesis x plus 2 right-parenthesis.(x + 2)

y – 2 = –y minus 2 equals negative StartFraction 5 Over 4 EndFraction left-parenthesis x minus 1 right-parenthesis.(x – 1)

y + 2 = y plus 2 equals StartFraction negative 5 Over 4 EndFraction left-parenthesis x minus 6 right-parenthesis.(x – 6)

y – 1 = –y minus 1 equals negative StartFraction 5 Over 4 EndFraction left-parenthesis x minus 2 right-parenthesis.(x – 2)

y – 3.5 = –1.25x

Answer:B. 42, 43

Step-by-step explanation:

STEP 1  Listing out the data set

Country    Time with dad

Belgium    30

Canada    44

China      54

Finland    50

Germany  36

Nigeria     42

Sweden    46

United States 42

STEP 2--- finding the mode and median

Mode----The mode of this  data set is the number that occurs most frequently in this research date.

Time with dad in ascending order is given as 30, 36, 42, 42, 44,46,50,54

The number that occurred the most is 42 = mode

Median The median is the middle value in a data set

Since these data set is an even number, we take the average of the two middle numbers

Arranging in ascending order, we have

30, 36, 42, 42, 44, 46, 50, 54---------------42 and 44 are the middle numbers

42+ 44/2 =43

Therefore mode and median are 42 and 43 respectively

Answer: 17 nickels, and 8 dimes.

Step-by-step explanation:

So Miles has 25 coins in his pocket, Suppose that x is the number of nickels, and y is the number of dimes, then we have that:

x + y = 25

And we also know that the total value is $1.65

Then we have that:

x*0.05 + y*0.10 = 1.65

Then we have a system of equations:

x + y = 25

x*0.05 + y*0.10 = 1.65

The first step is isolating one of the variables in one of the equations, i will isolate x in the first one.

x = 25 - y

Now we can replace that in the second equation:

(25 - y)*0.05 + y*0.10 = 1.65

Now we solve this for y.

25*0.05 - y*0.05 + y*0.10 = 1.65

1.25 + y*(0.10 - 0.05) = 1.65

y*0.05 = 1.65 - 1.25 = 0.40

y = 0.40/0.05 = 8

So Miles has 8 dimes.

And:

x + y = 25

x + 8 = 25

x = 25 - 8 = 17

And Miles has 17 nickels.

We want to multiply each term inside the parentheses by the number on the outside.

-3(-7)=21

-3(3z)=-9z

Therefore, our expression is 21-9z.

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]9 - 10x = 2x + 1 - 8x[/tex]

[tex]9-10x=-6x+1[/tex]

Subtract 9 from both sides:

[tex]9-10x-9=-6x+1-9[/tex]

[tex]-10x=-6x-8[/tex]

Add 6x to both sides:

[tex]-10x+6x=-6x-8+6x[/tex]

[tex]-4x=-8[/tex]

Divide both sides by -4:

[tex]\frac{-4x}{-4}=\frac{-8}{-4}[/tex]

[tex]x=2[/tex]

Answer:

x = 2

Step-by-step explanation:

9-10x = 2x+1-8x

1. move all like terms to one side

-10x-2x+8x = -9+1

2. simplify

-4x = -8

3. divide the -4 from both sides of the equation

x= -8/-4

4. x=2

Answer:

The charges of both companies will be same if truck is driven 200 miles per day

Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B

Step-by-step explanation:

Let the truck is driven X miles per day

Charges of company A will be = 90+0.4X

Charges of company B will be =30+0.7X

Let us find out value of X when charges of both companies are same

which means that   90+0.4 X= 30+0.7X

                            90-30      = 0.7X-0.4X

                            60    = 0.3X

                             60/0.3 = X

                             X= 200

200 miles

Answer:

The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

Step-by-step explanation:

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.

Answer:

The remaining materials from the sun's formation clumped together due to gravity.

Answer:

100 kilometers

Step-by-step explanation:

In order to answer this question, we are going to have to do some multiplication, division, and conversion! To get started, we have to multiply 20 cm by 500,000 to expand the distance to full-scale:

20 * 500,000 = 10,000,000

This is how many centimeters (cm) are between the towns. Now, we have to convert this into kilometers (km). There are 100,000 centimeters in a kilometer, so to convert we have to divide 10,000,000 cm by 100,000:

10,000,000 / 100,000 = 100

Our answer is 100 kilometers.

Hope this helps! :)

35% discount

Step-by-step explanation:

We can first find what percent of 32 20.80 is.

This can be shown by using a percent proportion.

[tex]\frac{20.80}{32} = \frac{x}{100}[/tex]

We can cross multiply to find the value of [tex]x[/tex].

[tex]20.80\cdot100=2080\\\\2080\div 32 = 65[/tex]

So 20.80 is 65% of 32.

However, this is the percent of the original price. To find the discount, we have to subtract 65 from 100.

[tex]100 - 65 = 35[/tex]

So the book was on a 35% discount.

Answer:

The 12.6 oz bottle

Step-by-step explanation:

0.19/oz for the 12.6 oz

0.21/oz for the 25.3 oz

The size is the better buy based on the unit price is 12.6 oz bottle if a certain shampoo is available in two sizes.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A certain shampoo is available in two sizes. A 12.6-ounce bottle costs $2.37. A 25.3-ounce bottle costs $5.24.

Let the unit price be x:

= 0.19/oz for the 12.6 oz

x = 0.21/oz for the 25.3 oz

Thus, the size is the better buy based on the unit price is 12.6 oz bottle if a certain shampoo is available in two sizes.

Answer:

[tex]y=3x[/tex] (Equation 1)

[tex]y=x-2[/tex] (Equation 2)

We can substitute Equation 1 into Equation 2 like so:

[tex]y=x-2[/tex]

[tex]3x=x-2[/tex]

Subtract x from both sides:

[tex]2x=-2[/tex]

Divide both sides by 2:

[tex]x=-1[/tex].

Substitute [tex]x=-1[/tex] into Equation 1 to find y:

[tex]y=3x[/tex]

[tex]y=3(-1)[/tex]

[tex]y=-3[/tex]

Answer:

2/3 ÷ 4=1/6

Step-by-step explanation:

2/3÷4=2/3×1/4

=1/3×2

=1/6

Step-by-step explanation:

We know that:-

Angle sum property if Triangles tells us that sum of angles of a triangle is equal to 180°.

So, First, we will find the third inner angle.

[tex]180 = y + 93[/tex]

[tex]y = 87[/tex]

Now, let us find x.

[tex]62 + 87 + x = 180[/tex]

[tex]149+ x = 180[/tex]

[tex]x = 31[/tex]

So, 31° is the answer. (c)
