It cost Benjamin $1.35 to send 9 text messages. How much would it cost to send 118 text messages?

1443.7

Step-by-step explanation:

1.35x9=12.15

12.15x118=1433.7

It would cost $17.70 to send 118 text messages

Step-by-step explanation:

\$1.35 ÷ \color{steelblue}{9}\text{ texts}=

$1.35÷9 texts=

\,\,\text{\color{indianred}{\$0.15} per text}

$0.15 per text

\color{indianred}{\$0.15}\text{ per text} × \color{seagreen}{118}\text{ texts}=

$0.15 per text×118 texts=

\,\,\text{\color{purple}{\$17.70} }

$17.70

\frac{\text{dollars}}{\text{texts}}=

texts

dollars

=

\,\,\frac{\text{dollars}}{\text{texts}}

texts

dollars

\frac{1.35}{9}=

9

1.35

=

\,\,\frac{\color{purple}{x}}{\color{seagreen}{118}}

118

x

We don't know how many dollars for 118 texts- call it xx

1.35\cdot\color{seagreen}{118}=

1.35⋅118=

\,\,9\cdot\color{purple}{x}

9⋅x

159.3=

159.3=

\,\,9\color{purple}{x}

9x

\frac{159.3}{9}=

9

159.3

=

\,\,\frac{9\color{purple}{x}}{9}

9

9x

Undo multiplication by dividing both sides by 9

17.7=

17.7=

\,\,\color{purple}{x}

It would cost $17.70 to send 118 text messages

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

  y  coordinate 

fy=ay+delta y*4/> fy=4+2*(8/> fy=5

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)
