There are three numbers. The first number is twice the second number. The third number is twice the first number. The sum of the
mel-nik [20]

Answer:

x = 32 y = 16 z = 64

Step-by-step explanation:

x is the 1st number

y is the 2nd number

z is the 3rd number

The first number is twice the second number so

x = 2 y

The third number is twice the first number.

z = 2 x

Their sum is 112

x + y + z = 112

Plus in what we know:

x + y + z = 112

2 y + y + 2x = 112

3y + 2x = 112 Let's solve for y and subtract 2x from each side

3y = 112 - 2x  Divide both sides by 3

y = \frac{112 - 2x}{3}

Now plug our answer back in to solve for x.

x = 2y

x = 2 ( \frac{112 - 2x}{3} )

x = (224 - 4x) / 3    Multiply each side by 3.

3x = 224 - 4x         Add 4x to each side

3x + 4x = 224

7x = 224              Divide each side by 7

7x / 7 = 224 / 7

x = 32

Now we can solve for z.

z = 2x

z = 2 ( 32 )

z = 64

Now we can solve for the numerical value of y.

x + y + z = 112

32 + y + 64 = 112

96 + y = 112       Subtract 96 from each side.

y = 112 - 96

y = 16

The cost of renting a car is 55 a week plus.35 mile traveled during that week an equation to represent the cost would be y=55+0.
uysha [10]

Answer:

65 miles

Step-by-step explanation:

y=55+0.35x

77.75 = 55+0.35x

77.75 - 55 = 0.35x

22.75 = 0.35x

22.75 ÷ 0.35 = 0.35x ÷ 0.35

65 = x

x = 65

For this case we have the following function:
 A (t) = A0e ^ {(kt)}&#10;
 Where,
 A0: initial population
 K: rate of change
 t: time in years
 Substituting values we have:
 A (t) = 22000 * e ^ {(- 0.021 * t)}&#10;
 For the year 2015 we have:
 A (t) = 22000 * e ^ {(- 0.021 * 5)}&#10;&#10;A (t) = 19807
 Answer:
 
the predicted population in 2015 is:
 
19,807
