Answer:

255 pesos

Step-by-step explanation:

17 x 15 = 225 pesos

Answer:

15

Step-by-step explanation:

If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,

4x-6+x=69

5x-6=69

5x=75

x=15

So, Maggie is 15.

Answer: Maggie is 15 years old

Step-by-step explanation:

69 = (4m - 6) + m     --- get an equation

69 - m = 4m - 6        --- lets subtract  m from both sides first

75 - m = 4m              --- add 6 on both sides

75 = 5m                    --- add m on both sides

15 = m                       --- divide by 5 on both sides

m = 15, so Maggie is 15 years old

Let's check:

69 = (4(15)-6) +15

69 = (60 - 6) + 15

69 = 54 + 15

69 = 69

Thus: a7=-1

Step-by-step explanation:

Arithmetic Sequences

The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

We know: a12=29, a16=53, thus

[tex]a_1+(12-1)r=29[/tex]

[tex]a_1+(16-1)r=53[/tex]

Simplifying:

[tex]a_1+11r=29[/tex]

[tex]a_1+15r=53[/tex]

Subtracting both equations:

[tex]4r=53-29=24[/tex]

Solving:

[tex]r=24/4[/tex]

r=6

The 7th term can be found as 5 terms before the 12nd:

[tex]a_7=a_{12}-5r[/tex]

[tex]a_7=29-5*6=29-30=-1[/tex]

Thus: a7=-1

Answer:

1. 125 cm and 275 cm

Step-by-step explanation:

1. 400 cm in total

  Subtract 150 for the longer stick and you are left with 250 cm.

  Divide 250 cm by 2 because you have two sticks, and you get 125.

  That's how long the shorter stick will be.

  For the longer stick, take the other 125 cm left and add the 150 cm that you subtracted earlier because that's how much longer it is than the shorter stick.

  So... 125 cm for the shorter stick, and 275 cm for the longer one

Answer:

2950

Step-by-step explanation:

i just subtracted 3,000 with 50

There are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.

What is random shuffle of songs?

Shuffle play is a type of music playback in which all tracks are selected at once and songs are played in a random order. Media player software, digital audio players, and CD players all frequently have it.

Given: You have 3,000 songs downloaded to your mobile phone.

Of these songs, 50 songs are by your favorite artist.

So, the number of songs would you have to listen in a row before you heard a song by your favorite artist are,

3000 - 50 = 2950.

Therefore, there are 2950 songs would you have to listen in a row before you heard a song by your favorite artist.

Answer:

B) y = 35°                

Step-by-step explanation:

Any quadriteral is you can add a line that links opposite corners of the quadrilateral and split it into two triangles. Added a single line the links opposite vertices of the quadrilateral and that splits it into two triangles. The angle rule that angles in a triangle add up to 180 degrees so the angle must add up to 180 degrees because of that angle rule and then in the other triangle the angles in that one must add up to 180 degrees. But the quadrilateral is made up of both triangles so you need all the angle in both those triangles to make up the angles of the quadrilateral so two lots of 180 degrees make up for 360 degrees. (180° plus 180° = 360°)

B) 118° plus 67° pus y plus 4y = 360°          ( add all the angles that are inside of the quadrlateral)

185° plus 5y = 360°                   ( 118 degrees plus 67 degrees is 185°, 5y from to y plus 4y. its like you have 1y plus 4y)

5y = 360° - 185°           ( subtract 180 degrees from both sides)

5y = 175°

divide by both side by 5, the value of y is 35°

Given parameters:

Dimension of the room  = 6 inches by 11 inches;

Unknown:

Area of the actual room = ?

Solution:

The area of the room = length x breadth

Now, we need to convert inches to feet;

                Scale;

                       1 inch = 1 foot

                        6 inches  = 6 foot

                       1 inch = 1 foot

                       11 inch = 11 foot

The area of the room = 6 x 11 = 66 square feet

5.25

Step-by-step explanation:

hint: anytime you see a - before (  and its not like (for example) -2 then you put a 1 like this -1(

2-1(4x+8)= -12

2-4x+7= -12

(combine like terms [2 and 7 in this case] )

9-4x= -12

X+y=-5

-x -x

y=-x-5 is the ending equation.

How to graph:

The y-intercept, or point where the graph starts, is -5

From there go down 1, right 1.

M=-x

B=-5

Answer:  m = -1   b = -5

Step-by-step explanation:

Rewrite the equation in "slope-intercept form"   y = mx +b .

m is the slope  

b is the y-intercept, where the graph of the line crosses the y-axis

To rewrite the equation, to get "y" alone on the left side, subtract x from both sides:

x + y = -5

-x + x + y = -x - 5  (left side -x +x =0 so "cancel")

y = -x -5

You get  the slope "m" from the coefficient of x, (invisible 1, sometimes)

since there is a negative sign, the coefficient is -1   That is m, the slope.

A negative slope goes down from left to right.

For  -1, down one over 1 square.

Your graph should look like the screenshot below.

Step-by-step explanation:

Step-by-step explanation:

Hey there!

The point shows the coordinates of (-2,1) and (4,6).

Now, When two points are given on a st.line, we use double point formula.

So, use formula;

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)[/tex]

Put all values of x and y coordinates.

[tex](y - 1) = \frac{6 - 1}{4 + 2} (x + 2)[/tex]

Simplify it.

[tex](y - 1) = \frac{5}{6} (x + 2)[/tex]

[tex]y = \frac{5}{6} x + 2 \times \frac{5}{6} + 1[/tex]

[tex]y = \frac{5}{6} x + \frac{ 8}{3} [/tex]

Therefore, the equation of a line is y= 5/6x+8/3.
