Solve for x. 2 1/2x − 3/4 (2x+5) = 38 ASAP
svetoff [14.1K]

Answer:

  x = 41 3/4

Step-by-step explanation:

(2 1/2)x -(3/4)(2x +5) = 38

(2 1/2)x -(1 1/2)x -15/4 = 38 . . . . use the distributive property

x = 38 +3 3/4 . . . . . . add 15/4

x = 41 3/4

_____

Another way to solve this is to "clear fractions" by multiplying the whole equation by 4:

  10x -3(2x +5) = 152

  4x -15 = 152 . . . . eliminate parentheses

  4x = 167 . . . . . . . add 15

  x = 41 3/4 . . . . . . divide by 4

The population of rabbits on an island is growing exponentially. In the year 1990, the population of rabbits was 1200, and by 19
kobusy [5.1K]

Answer:

2023 rabbits

Step-by-step explanation:

The exponential model consists of the following expression:

y = A \cdot r^{t}

Where:

A - Initial population.

r - Increase rate.

t - Time

y - Current population.

The initial population and increase rate are, respectively:

1200 = A \cdot r^{0}

A = 1200

1700 = 1200 \cdot r^{4}

r^{4} = \frac{1700}{1200}

r^{4} = \frac{17}{12}

r = \sqrt[4]{\frac{17}{12} }

r \approx 1.091

The exponential model that predicts the population of rabbits is:

y = 1200\cdot 1.091^{t}

Lastly, the expected population for the year 1996 is:

y = 1200\cdot 1.091^{6}

y\approx 2023.624\,rabbits
