Find two numbers if their sum is 6.1 and their difference is 1.6
Radda [10]
For this case, the first thing we must do is define variables:
 x: unknown number (1)
 y: unknown number (2)
 We now write the equations that model the problem:
 their sum is 6.1:
 x + y = 6.1

 their difference is 1.6:
 x - y = 1.6

 Solving the system we have:
 We add both equations:
 x + x = 6.1 + 1.6

2x = 7.7

x = 7.7 / 2

x = 3.85
 Then, we look for the value of y using any of the equations:
 x - y = 1.6

y = x - 1.6

y = 3.85 - 1.6

y = 2.25
 Answer:
 
The numbers are:
 
x = 3.85

y = 2.25

Answer:

  50 ft

Step-by-step explanation:

The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.

In this geometry, that means the length of the escalator is 2 times its height, so is ...

  x = 2(25 ft)

  x = 50 ft . . . . . distance a person travels

Twenty years ago, you began investing $3,000 a year. Because your investments earned an average of 8 percent a year, your invest
Ulleksa [173]

Answer:

$32,000

Step-by-step explanation:

Yearly investment = $3,000

Number of years = 20

Investments earned an average of 8 percent a year.

Total invested amount = $3,000 × 20 = $60,000

Current value of investment = $92,000.

We need to find the total earnings on the investment.

Earnings = Current value of investment - Total invested amount

Earnings = $92,000 - $60,000

Earnings = $32,000

Therefore, the total earnings is $32,000.
