Paul picked and bagged a total of 30 pounds of apples on Saturday and Sunday. He filled each bag with 5 pounds of apples. On Saturday, Paul filled 2 bags with apples. How many bags did Paul fill with apples on Sunday? Complete and solve the equation to show how many bags Paul filled with apples on Sunday.

Answers

Answer:

Paul filled 4 bags on Sunday.

Step-by-step explanation:

Since each bag that was filled weighed 5 pounds then we can use the following equation to solve for the amount of bags, where (x) is the number of bags filled on Saturday and (y) is the number of bags filled on Sunday.

5x + 5y = 30

Now since we are told that on Saturday Paul filled 2 bags then we would only be left with the variable y (number of bags filled on Sunday). We can solve for y

5(2) + 5y = 30

10 + 5y = 30 ... subtract 10 on both sides

5y = 20 ... divide by 5 on both sides

y = 4

Finally, we can see that Paul filled 4 bags on Sunday.

$\log_2(5x - 2) - \log_2 x - \log_2(x - 1) = 2$
$\log_2 ( (5x - 2)/(x(x-1)) ) = 2$
$\log_2 ( (5x - 2)/(x(x-1)) ) = \log_2 4$
$(5x - 2)/(x(x-1)) = 4$
$5x - 2 = 4x(x - 1)$
$5x - 2 = 4x^2 - 4x$
$0 = 4x^2 - 9x + 2$
$0 = (4x - 1)(x - 2)$
$\implies x = 2 \text{ or } x = (1)/(4)$

By putting one quarter into the equation we can see that it cannot work in any way involving real numbers as $\log_2 ( (1)/(4) - 1)$ would be log of a negative number, so x = 2.

   a⁴(3a² - 2a + 1)

We just have to multiply each term inside the parentheses by a⁴ .

   a⁴(3a² ) = 3a⁶

   a⁴( - 2a ) = -2a⁵

   a⁴( 1) = a⁴

Now, just addum up : 3a⁶ - 2a⁵ + a⁴
