Bob borrows $5.50 from his friends three times a week. Write an equation to repress the change in Bob's money this week

Answer:

Step-by-step explanation:

16)

 [tex]\frac{4}{10} , \frac{32}{72}\\\\\frac{4}{10} = \frac{32}{72}[/tex]

Cross multiply,

4 * 72   = 32 * 10

  288   ≠   320

So, these are not in proportion.

17)

[tex]\frac{40}{25} = \frac{32}{20}[/tex]

Cross multiply,

40 * 20 = 32 * 25

800  = 800

So, these are in proportion.

18)

[tex]\frac{15}{45}=\frac{9}{c}[/tex]

Cross multiply,

15 * c = 9*45

      c = [tex]\frac{9*45}{15}[/tex]

      c = 9*3

     c = 27

19)

[tex]\frac{16}{120} = \frac{v}{15}[/tex]

Cross multiply

16 * 15 = v * 120

[tex]\frac{16*15}{120} =[/tex] v

v = 2

Answer:

4) The square root of 25 is rational

5) pi is irrational

Step-by-step explanation:

To know if the answer is rational or irrational, check to see if they can be turned into a fraction.

Answer:

4) [tex]\sqrt{25}[/tex]

5) [tex]\pi[/tex]

Step-by-step explanation:

4) [tex]\pi[/tex] is irrational.

[tex]\sqrt{2}[/tex] and [tex]\sqrt{3}[/tex] are also irrational.

[tex]\sqrt{25}[/tex] = 5. 5 is a whole number and thus is rational.

5) 16.5% = [tex]\frac{16.5}{100}[/tex]

0.0675 is a terminating decimal so it is rational.

8[tex]\frac{3}{4}[/tex] = 8.75 is also a terminating decimal so it is rational.

Answer:

Step-by-step explanation:

<1 is the supplement of 5x + 5.  You have to assume that the almost horizontal lines are parallel. In addition, two angles on the same side of a transversal across two parallel lines and are interior angles are supplementary.

5x + 6 + 7x - 18 = 180                   Add  like terms

12x - 12 = 180                                Add 12 to both sides

12x = 180 + 12

12x = 192                                      Divide by 12

x = 192 /12

x = 6

====================

5x + 6 = 5*12 + 6

5x + 6 = 60 + 6

5x + 6 = 66

<1 + 66 = 180

<1 = 180 - 66

<1 = 114

Answer: B) y = -x^4

Work: I just plugged in the numbers into all the equations listed, and B worked correctly for them all, thus that's the correct answer.

I hope this helps, and Happy Holidays. :)

Step-by-step explanation:

Why would you submit FICTIONAL dates for a autobiography about

your REAL life.

Answer:

156cm

470+30+8=508cm

Step-by-step explanation:

Answer:

At 15 movies, both will cost $175

Step-by-step explanation:

Set it up algebraicly. Let x be the number of movies

100 + 5x = 25 + 10x

75 + 5x = 10x

75 = 5x

x = 15

Lets substitute x into one equation

100 + 5(15)

100+75

175

Answer:

I think is B

because its the one that sounds good

Answer:

=3x^2+8x+8

Step-by-step explanation:

Answer:

For E, each angle is 60° because its an equilateral triangle.

F is 45° for x, 135° for y, lastly z is 22.5°

Answer:

y= -9x+ 5/4

Step-by-step explanation:

y=mx+b

m is slope and b is y intercept

Answer:

x+8z-9y-ty

2x+5z-9y + x-8z+9y+ty

=3x+ty-3z

Answer: The quantity a plus b doubled

               Twice the quantity of a and b

Step-by-step explanation: You're multiplying the sum of a and b by two. Multiplying by two and doubling is the same. Twice is a synonym for two times. there is no addition happening that involves 2 and there is no subtraction with a and b so the second and fourth choice are eliminated.

Hi! The solution is 2(2q+5)

2. Multiply

3. Combine like terms

4. Find common factor

Hope this helps! Have a good day!! :)

Answer:

No, because the amount of money on her gift card should decrease each week.

Step-by-step explanation:

Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be  decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.

Answer:

Slope = ∆y/∆x

slope = ( -5_1 ) / ( 3_-3 )

slope = -6 / 6

slope = -1

Step-by-step explanation:

I have attached an image of the graph of this inequality from Desmos, a virtual graphing website to help answer your question.

However, to explain this graph, each and every x value less than or equal to 5 would be an appropriate solution to the inequality, thus all values less than or equal to 5 are shaded in.

Slope formula - [tex]\frac{y2-}{x2-} \frac{y1}{x1}[/tex]

First coordinate pair - (-1, -4)

Second coordinate pair - (3, 1)

Coordinate format - (x, y)

y2=1, y1=-4

x2=3, x1=-1

[tex]\frac{1-}{3-} \frac{(-4)}{(-1)} =\frac{5}{4}[/tex]

Hope this is what your looking for :)

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.
