Answer:

$24,800

Step-by-step explanation:

If a car is worth 8% less after one year, then it is worth 92% of the original value.

original value = x

after 1 year: 0.92x

after 2 years: 0.92(0.92x)

after 3 years: 0.92(0.92(0.92x))

0.92³x = $19,311.46

x = $19,311.46/0.92³

x = $24,800

Uncle Jason is twice as old as his nephew Ralph, and 10 years ago he was three times as old as Ralph. Find their present ages.
cluponka [151]

Answer:

40 and 20

Step-by-step explanation:

  • Uncle Jason's age = x
  • Nephew Ralph age = y
<h3>Solution</h3>

<u>Age now:</u>

  • x= 2y

<u>Age 10 years ago: </u>

  • x- 10 = 3(y-10)

<u>Substituting x in the second equation:</u>

  • 2y - 10 = 3y - 30
  • 3y - 2y = 30 -10
  • y = 20

<u>Then, finding x:</u>

  • x= 2y
  • x= 2*20
  • x= 40

<u>Answer:</u> Uncle Jason is 40 and nephew Ralph is 20 years old

What is the angle of B
Charra [1.4K]
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126

so, Angle B is 126 degrees

I hope that helps!
