Two towns that are 31.5 km apart are 3 cm apart on a map. what is the scale of the map?
VLD [36.1K]

<u>Answer:</u>

1 cm : 10.5 km

<u>Step-by-step explanation:</u>

We are given that two towns are 31.5 km in real and are 3 cm apart on a map and we are to find the scale of the map.

For this, we can use the ratio method.

\frac { 3 cm } { 1 c m } = \frac { 3 1 . 5 k m } { x }

x = \frac { 3 1 . 5 \times 1 } { 3 }

x = 1 0 . 5

Therefore, the scale of the map would be 1 cm : 10.5 km.

Answer:The system of equations to describe the situation are

c + y = 8

6c + 3y = 36

Step-by-step explanation:

Let c represent the number of shirts.

Let y represent the number of caps.

Eight friends started a business. They will wear either a baseball cap or a shirt imprinted with their logo while working. This means that

c + y = 8 - - - - - - - - - - -1

They want to spend exactly $36 on the shirts and caps. Shirts cost $6 each and caps cost $3 each. This means that

6c + 3y = 36 - - - - - - - - - - 2

Please help with the following question
sasho [114]
  We have:
  The generic equation of the line is:  y-yo = m (x-xo)
  The slope is:
  m = (y2-y1) / (x2-x1)
  m = (- 2-0) / (3-0)
  m = -2 / 3
  We choose an ordered pair
  (xo, yo) = (0, 0)
  Substituting values:
  y-0 = (- 2/3) (x-0)
  Rewriting:
  y = (- 2/3) x
  Answer:
  The equation of the line is:
  y = (- 2/3) x
