madreJ [45]3 years ago
7 0

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

C(r) = 2.3r + 6.5

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when r = 0, which is C(0)

C(0) = 2.3*0 + 6.5 = 6.5

The cost of the mug is of $6.50.

Write an equation representing the fact that the product of two consecutive odd integers is 255. use x to represent the smaller
USPshnik [31]

The first odd number = 15

The second is then = 17

<h3>The Consecutive numbers are:</h3>

Consecutive numbers are those that appear consecutively after one another in the range of smallest to largest. An illustration would be the sequence of numbers 1, 2, 3, 4, 5, and so on.

<h3>Where can I find consecutive numbers?</h3>

Let x be the first of the following numbers to represent it algebraically. Following that, the numbers x + 1, x + 2, and x + 3 would be arranged in order. You must make sure that your first selection is an even number if the question requires consecutive even numbers.

<h3>According to the given information:</h3>

We can employ the expression "2n," where n is any integer, to ensure that the result is even. By using the expression "2n + 1," we can ensure an odd number.

"2n + 3" will be the following odd number:

(2n + 1)(2n + 3) is the component of the odd integers, and it equals 255:

(2n + 1)(2n + 3) = 255

4n2 + 8n + 3 = 255

4n2 + 8n - 252 = 0

n2 + 2n - 63 = 0

(n + 9)(n -7) = 0

n = -9 and n = 7

We can disregard n = -9 because we are informed that the figures must be positive.

If n = 7,

The first odd number = 2(7) + 1 = 15

The second is then 17
