Answer:

x = 5/4

y = 7/4

Step-by-step explanation:

The smaller triangle and the larger one are similar, so the sides are proportional.

(x+5)/5 = 10/8

x/5 + 1 = 1/4 + 1 . . . . . divide it out

x/5 = 1/4 . . . . . . . . . . .subtract 1

x = 5/4 . . . . . . . . . . . . multiply by 5

___

For y, you can do exactly the same computations, replacing every instance of 5 with a 7. Then you get ...

y = 7/4

When placed end to end, three red rods are 2 cm longer than than 2 blue rods. Three blue rods are 2 cm longer than four red rods
Oxana [17]

Answer:

Red = 10 cm, blue = 14 cm

Step-by-step explanation:

<em>Let the length of each red rod be </em><em>r </em><em>and each blue rod be </em><em>b</em>

<u>Then we have:</u>

  • 3r - 2b = 2
  • 3b - 4r = 2

<u>Multiply the first equation by 3 and the second one by 2:</u>

  • 9r - 6b = 6
  • 6b - 8r = 4

<u>Add the equations to eliminate one of variables:</u>

  • 9r - 8r = 6 + 4
  • r = 10 cm

<u>Find the value of b:</u>

  • 3*10 -2b = 2
  • 30 - 2 = 2b
  • 2b = 28
  • b = 14 cm
