Just the 3rd and 4th plz help me
svlad2 [7]

Answer:


Step-by-step explanation:

Now the key here is manipulating the scale:

For 3 every 2cm = 15mi

Divide by 2 so every 1cm = 7.5mi

So if we had 16.27cm then that would equal 16.27 x 7.5 = 122.025mi on the actual scale

Same for 4: if 1/2cm = 20mi

Then multiply times 2 and every 1cm = 40mi

So 11.73cm x 40 = 469.2mi on the actual scale

Hopefully this is right and it helps!

Estimate the solution to the system of equations.
Leona [35]

Answer:

\sf C)  \  x = -1\dfrac{2}{5}  , \  y =  \ 1\dfrac{3}{5}

Given equations:

  • a) -3x + 3y = 9
  • b) 2x - 7y = -14

<u>Make x the subject in equation 1</u>:

  • -3x + 3y = 9
  • -3x = 9 - 3y
  • x = y - 3

<u>Substitute this into equation 2</u>:

2(y - 3) - 7y = -14

2y - 7y = -14 + 6

-5y = -8

  y = -8/-5

  y = 1.6

Then x = y - 3

           = 1.6 - 3

           = -1.4

Solution: (x, y) ⇒ (-1.4, 1.6)
