Answer:

  • 18. x = 24.5
  • 19. x = 4
  • 21. x = 10

Step-by-step explanation:

Corresponding sides have same ratio

Q18

  • 7/6 = x / (27- 6)
  • 6x = 7*21
  • x = 147/6
  • x = 24.5

Q19

  • (x + 5)/15 = (5x + 1)/35
  • (x + 5)/3 = (5x + 1)/7
  • 7(x + 5) = 3(5x + 1)
  • 7x + 35 = 15x + 3
  • 15x - 7x = 35 - 3
  • 8x = 32
  • x = 4

Q21

  • (x + 6)/24 = (2x - 2)/27
  • (x + 6)/8 = (2x - 2)/9
  • 8(2x - 2) = 9(x + 6)
  • 16x - 16 = 9x + 54
  • 16x - 9x = 54 + 16
  • 7x = 70
  • x = 10

Answer:

Step-by-step explanation:

A median is a line that joins the angle vertex to the the point that is located at 1/2 the distance across the the line.

Where the medians meet is the centroid.

The centroid divides the median into a ratio of 2 to 1.

HM/ML = 2/1

ML = 20

HM / 20 = 2/1         Multiply both sides by 20

HM = 2 * 20

HM = 40

Pens are on sale for 3 pens for $6 Karen bought 3 pens Leo bought 1 pen how much more did Karen spend than Leo
Rasek [7]
If the correlation is correct, then 1 pen would be equal to $2. In this case, karen spent $2 for each pen for a total of 3 pens for $6. If Leo bought 1 pen, he would spend $2. So, $6-$2=$4. Karen spent 4 more dollars than Leo. If this helped, please mark me brainliest, thank you and if you need more help, feel free to message me!
