Marcel wants to buy a bike for 499$. he has already saved 256$. His grandma gives him 50$. He can save 12$ per month. How long does he have to wait before he can afford the bike?​

Answer:

you divide 4 by those numbers then you keep going higher

Step-by-step explanation:

Step-by-step explanation:

-3x+7y = -18 ...1

4x-4y = 8 ...2

...1 × 4

-12x + 28y = -72 ...3

...2 × 3

12x - 12y = 24 ...4

...3 + ...4

28y - 12y = -72 + 24

16y = -48

y = -3

Replace y = -3 in ...2

4x - 4(-3) = 8

4x + 12 = 8

4x = 8 - 12

4x = -4

x = -1

Answer:

[tex]\huge\boxed{\boxed{(x,y)=(-1,-3)}}[/tex]

Step-by-step explanation:

multiply first equation by 4 and second by 3 respectively:

[tex] \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}[/tex]

combine the equations:

[tex] \underline{ \begin{cases} \displaystyle - 12x + 28y = - 72 \\ \: \: \displaystyle \: 12x - 12y = 24 \end{cases}} \\ \displaystyle16y = - 48[/tex]

divide both sides by -48:

[tex] \displaystyle \: \frac{16y}{16} = \frac{ - 48}{16} \\ y = - 3[/tex]

substitute the value of y to the second equation

[tex] \displaystyle \: 4x - 4. - 3 = 8[/tex]

simplify multiplication:

[tex] \displaystyle \: 4x + 12 = 8[/tex]

cancel 12 from both sides:

[tex] \displaystyle \: 4x = - 4[/tex]

divide both sides by 4

[tex] \displaystyle \: \frac{4x}{4} = \frac{ - 4}{4} \\ x = - 1[/tex]

therefore our solution is

[tex]\displaystyle (x,y)=(-1,-3)[/tex]

Have a nice day.

Answer:

7y+24x = -12

Step-by-step explanation:

Equation of line PQ in point slope form is expressed as;

y -y0 = m(x-x0)

m is the slope of {Q

(x0, y0) is the point on the line

Given the line 7x-24y+10=0

Get the slope

-24y = -7x -10

y = -7/-24 x - 10/-24

y = 7/24 x + 5/12

Slope = 7/24

Slope of the line PQ perpendicular to it = -24/7

Substitute m = -24/7 and (-2, 4) into the formula;

y - 4 = -24/7(x+2)

7(y-4) = -24(x+2)

7y - 28 = -24x-48

7y + 24x = -40 + 28

7y+24x = -12

This gives the equation of the line PQ

Answer:

Step-by-step explanation:

(x-3)(x-4)/(x-4)

The (x-4)'s divide out.

Given:

Consider the below figure attached with this question.

To find:

The correct statements about the given box and whisker plot.

Solution:

In a box plot, the left end of the box is first quartile and the right end of the box is third quartile. The line inside the box represents the median.

Left end point represents the minimum value and the right end point represents the maximum value.

From the given box plot, it is clear that

Minimum value = 35

First quartile = 42

Median = 49

Third quartile = 54

Maximum value = 57

The median of the data is 49. The least number of calls is 35. So, options B and C are correct.

The third quartile is represented by 54. So, option D is incorrect.

The mean cannot be determined by the box and whisker plot. So, option E is correct and option A is incorrect.

Therefore, the correct options are B, C and E.

Answer:

Step-by-step explanation:

look at each picture to see what they are stating is the same in each of the triangles... the marks thur the lines means they are the same length, or the double or triple arcs in the angles means those are the same.  so if there are two sides that are the same... you can say SSS , if there are two angles that are the same you can say  ASA  .  the one where there is one side and one angle the same  you can say SAS .... hmmm  kinda get it?

Answer:

Radius is 3

Height is 4

Step-by-step explanation:

First you'll have to find the radius

6/2=3

Then, use the formula Base (PI*radius squared)* height

To find the base, you'll have to use the radius, 3, times it by itself, 3, and get 9.

3*3=9

Then, multiply 9 by 3.14, first three digits of pi, and get 28.26

9*3.14=28.26

28.26=base

Now, you'll have to find the height

Since you know what the volume is 36 pi 3

36*3.14=113.04 <--volume without pi

Then, divide 113.04 (volume) by 28.26 (base) and get 4 (height)

113.04/28.26=4

That's why the radius is 3 and the height is 4

Answer: (0.-7)

Step-by-step explanation:

Take the equation

y=x-7

The last number 7 is the Y-intercept

(0.-7)

Answer:

(0,-7)

Step-by-step explanation:

Hey There!

So we can easily find which one is a solution but taking an order pair and plugging in the x value

then we solve for y and if we get the value of y that is with the matching x value then it is a solution

for example for the first pair we plug in -1 to x

-1-7=-8

-8 does not equal -6 therefore the first one is not a solution

for the second one we plug in 0 to x

0-7=-7

-7=-7 therefore it is a solution

but lets just check the rest to be safe

for the third one we plug in 8 to x

8-7=1

-1 does not equal 1 thus it is not a solution

for the last one we plug in -1

-1-7=-8

-8 does not equal 6 therefore it is not a solution

so we can conclude that the second one is a solution

Answer:

The square is 731

Step-by-step explanation:

Let me try...13 , 1 + 35 + 7, 1 + 3 + 57 + 9 + 11 , 1 + 3 + 5 + 79 + 11 + 13 + 15 ...(1)

grab the main number in each sequence: 13,35,57,79,911,1113....

There is another arithmetic sequence: 1, 3, 5, 7, 9, 11 ....

a₁ = 1    aₙ = 2n - 1

365367 : 2n - 1 = 365       2n = 366      n = 183  ... 365367 is in the place 183 of the series sequence

Now let's check the number follow the underlined number in (1)

0 number follow 13, 1 number follow 35, 2 number follow 57, 3 follow 79 ....

0, 1, 2, 3, 4........ until n=183 should have 182 numbers followed 365367

Now this last sequence start with 369 (a₁) with a difference of 2 from term to term

a₁₈₂ = 2n + 367 = 2 x 182 + 367 = 731

Answer:

175

Step-by-step explanation:

hey! so it's basically an "estimate" meaning that you can round all the measurements up to the nearest whole number. and since finding the prism's volume is l*h*w divided by 2, i did 7*5*10 and got 350. half of 350 is 175 which is the volume of the prism :)

Answer:

175

Step-by-step explanation:

the formula of triangular prism is

v = 1÷2( b×h×l)

base (b) =5.1cm

height( h) = 6.9

length ( l) = 9.9

v =1÷2 ( 5.1 × 6.9× 9.9 )

v = 174.19 cm^3

so th closest will be 175cm^3

Answer:

721 hours

Step-by-step explanation:

Skills needed: Multiplication, Logical Reasoning

1) First, we need to gather information:

--> November has 30 days

--> There are 24 hours in each day

2) This means that there are:

[tex]24 * 30[/tex]  = 720 days in November without counting daylight savings.

3) With daylight savings:

--> We add one extra hour, since we go one hour back. So that day, 1:59 would go back to 1:00, with an extra hour.  So we add one to the total. [tex]720 + 1 = 721[/tex] is your answer

Hope this helps and have a nice day! :) :}
