The scale factor to dilate from rectangle A to rectangle B is ?

Answer:

56 students

Step-by-step explanation:

The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.

Answer:

23. y = 47

Step-by-step explanation:

40 + 5x =180 (angls on a straight line add up to 180 degrees)

5x=140 (minus 40 from both sides)

x = 28 (divide both sides by 5)

3y - 1 = 140

3y =141 (add 1 to both sides)

y = 47 (divide both sides by 3)

Answer:

y=47

Answer:

distance = y = (45 mph)*x

Step-by-step explanation:

distance = rate times time, so

in this case:

distance = y = (45 mph)*x

Answer: y=-1/2x-4

Step-by-step explanation:

If you use point slope formula you get

y+2=-1/2(x+4)

simplify that in y=mx+b and you get

y=-1/2x-4

Answer:

what

Step-by-step explanation:

Distance = 13 units

Point A: (8, -7)

Point B: (-4, -2)

[tex]\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }[/tex]

[tex]\sqrt{(12)^{2} + (-5)^{2} }[/tex]

[tex]\sqrt{144 + 25 }[/tex]

[tex]\sqrt{169}[/tex]

[tex]13[/tex]

Answer:

[tex]\boxed {d = 13}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two following points:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following onto the formula:

[tex](x_{1}, y_{1}) = (8, -7)[/tex]

[tex](x_{2}, y_{2}) = (-4, -2)[/tex]

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

-Solve for the distance:

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]

[tex]d = \sqrt{144 + 25}[/tex]

[tex]d = \sqrt{169}[/tex]

[tex]\boxed {d = 13}[/tex]

Therefore, the distance is [tex]13[/tex].

Answer:

y=-6x+36

Step-by-step explanation:

у + 6x — 36 = 0

-add 36 to both sides

y+6x=36

-subtract 6x from both sides

y=36-6x or y=-6x+36

-This should be the correct answer

Answer:

Step-by-step explanation:

Given the frequency vibrations for a certain guitar string modeled by the equation

F = 200√T where:

T is amount of tantrums in pounds

If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:

600 = 200√T

Divide both sides by 200

600/200 = 200√T /200

3 = √T

Square both sides

3² = (√T)²

9 = T

T = 9

Hence 9 pounds of tantrum was used to plug the string

b) The amount of clay for 8 bowls will be [tex]5\frac{1}{3}[/tex] pounds.

It is given that the double number line shows the amount of clay Jamal uses to make different numbers of identical bowls.

We have to solve the subparts of the question to get the values.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , division , etc.

As per the question ;

The clay needed per bowl = [tex]\frac{2}{3}[/tex] pounds

a)

The equation for clay (c) to make b number of bowls will be ;

c =  [tex]\frac{2}{3}[/tex] × b

or

c =  [tex]\frac{2}{3}[/tex] b

b)

If there are 8 number of bowls

i.e., b = 8

Then ; amount of clay Jamal needs will be ;

c =  [tex]\frac{2}{3}[/tex] × 8

c = [tex]\frac{16}{3}[/tex] pounds

or

c = [tex]5\frac{1}{3}[/tex] pounds

Thus , the answers will be ;

a) The required equation will be c =  [tex]\frac{2}{3}[/tex] b

b) The amount of clay for 8 bowls will be [tex]5\frac{1}{3}[/tex] pounds.

Answer:

L=-25t+200

Step-by-step explanation:

An equation is formed of two equal expressions. n=2m can be proved by solving the two of the given equation for h and then equating them together as shown below.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the two equations, 2n=m+h, and h=n+m. Now, solve the two of the equations for h as shown below.

Equation 1.

2n = m + h

2n - m = h

h = 2n - m

Equation 2.

h = n + m

Further, equate the value of h from both the equation,

h = h

2n - m = n + m

Bring the like terms on the same side of the equation,

2n - n = m + m

n = 2m

Hence, proved n=2m.

Answer:

-I

Step-by-step explanation:

Answer:

sample answer:   If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4

Step-by-step explanation:

The situation is a representation of the linear function.

Given that,

One dollar is divided into four quarters.

The total number of dollars is a function of the number of quarters.

Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value

As a result, the slope should be 1/4.

y = 1/4x should be the linear function.

Hence, As a result, we can conclude that the situation is a linear function.

Answer:

It would take him 8 hours

Since every 50 miles takes 1 hour

━━━━━━━☆☆━━━━━━━

▹ Answer

8 Hours

▹ Step-by-Step Explanation

First, find the unit rate:

100 miles ÷ 2 hours = 50 mph

Now, we need to find the time it takes to drive 400 miles so we will divide:

400 miles ÷ 50 mph = 8 hours

If you are looking for total hours, you would add:

2 hours + 8 hours = 10 hours

If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.

Answer:

B

Step-by-step explanation:

Answer: the answer is d/f+3

sorry i couldnt find my work for this problem but i hope it helps !

An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

fb + 3b = d

Take b as a common term from both the terms on the left side of the equation,

b(f + 3) = d

Divide both the sides of the equation by (f+3),

b(f + 3)/(f+3) = d/(f+3)

Simplify,

b = d/(f+3)

Hence, when in the given equation the value fo b is d/(f+3).

Answer:

the two numbers are 31 and 32.

Step-by-step explanation:

x+(x+1)=63

2x+1=63

2x=62

x=31

The answers are 31 and 32

The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get

x + x+1 = 63

Simpifying, you get

2x+1 = 63

Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.

2x=62

Lastly, you need to divide both sides by 2, making making the equation

x=31

The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.
