What is the substitution for the equation

Answers

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]

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.

What is the midpoint of a segment with endpoints at(-4,-8) and (8, 10)?

Answers

Answer:

The answer is

( 2 , 1)

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,-8) and (8, 10)

The midpoint is

[tex]M = ( \frac{ - 4 + 8}{2} , \: \frac{ - 8 + 10}{2} ) \\ = ( \frac{4}{2} , \frac{2}{2} )[/tex]

We have the final answer as

( 2 , 1)

ANSWER:-

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]

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

Answers

[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

How were the planets in the solar system formed?(1 point)

They developed from the dust that gravity attracted from distant galaxies.

They formed from material remaining after the sun's formation clumped together by gravity.

They came from the gas that the sun released and gravity pulled far away.

They were forced out of the central disc by the gravity that formed the sun.

Answers

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.

Bill found a book he wanted on sale for $20.80. The original price of the book was $32. Find the discount rate.

Answers

Answer:

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.

A truck can be rented from Company A for $130 a day plus $0.50 per mile. Company B charges $50 a day plus $0.70 per mile to rent the same truck. How many miles
must be driven in a day to make the rental cost for Company A a better deal than Company B's?
For Company A to have a better deal, the truck must be driven more than miles per day

Answers

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

Miles has 25 coins in his pocket. Some are nickels and some are dimes. He has a total of $1.65. How many of each type of coin does he have? Let x represent _____________________________ Let y represent _____________________________ System: _____________________ _____________________ Solution: x = ____________ y = ____________

Answers

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.

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.

What is a linear equation?

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.
