The sum of two numbers is 32. Five times the smaller number minus twice the larger number is 195.What are the numbers ?
Harlamova29_29 [7]

Answer:

  • 37 and -5

Step-by-step explanation:

Le the numbers be x and y

<u>Then we have equations:</u>

  • x + y = 32
  • 5x - 2y = 195

<u>As per the first equation:</u>

  • y = 32- x

<u>Substitute in the second equation</u>

  • 5x - 2(32 - x) = 195
  • 5x + 2x - 64 = 195
  • 7x = 195 + 64
  • 7x = 259
  • x = 259/7
  • x = 37

<u>Then finding the value of y</u>

  • y = 23 - 37 = -5

Find the scale factor of the dilation. Then tell whether the dilation is a reduction or an enlargement
Marta_Voda [28]

Answer:

The answer is "\frac{3}{7}"

Step-by-step explanation:

Please find the complete question:

The dilation scale factor will be the same:

=\frac{\text{Picture to Center Gap}}{\text{Related pre-image distance to the middle}}

Throughout the picture, the distance is CP'=6, while the equivalent distance is CP=14. The factor of scale is then=\frac{CP'}{CP} =\frac{6}{14} =\frac{3}{7}

The decrease because if a factor of scale is below 1 and a factor of scale is higher than 1. Dilation is a reduction since \frac{3}{7}, therefore the scale factor is \frac{3}{7}.
