Answer:

  • 3x-5>6x-14
  • Number of Ribbons is less than 3

Step-by-step explanation:

Let the number of  blue ribbons Betty has=x.

  • Three times the number of blue ribbons decreased by 5=3x-5
  • Six times the number of blue ribbons decreased by 14=6x-14

Since three times the number of blue ribbons decreased by 5 is greater than six times the number of blue ribbons decreased by 14.

Therefore an inequality that can be used to determine the number of blue hair ribbons:

3x-5>6x-14

Next, we solve the inequality to determine the number of blue ribbons Betty has, x.

Given:

3x-5>6x-14

Collect like terms

-5+14>6x-3x

9>3x

Divide both sides by 3

3>x

x<3

Therefore, Betty has less than 3 ribbons.

Answer:

3x-5> 6x- 14

Step-by-step explanation:

Let the blue ribbons be denoted by the letter x.

Then according to the given condition

3 times the blue ribbons = 3x

Decreased by 5 = 3x-5

is greater than

6 times the blue ribbons = 6x

decreased by 14 = 6x-14

Putting in one line

3x-5> 6x- 14

Solving the inequality

3x-5> 6x- 14

Taking both sides positive as in modulus

14-5 > 6x-3x

9> 3x

9/3 > x

3> x

Again solving for inequality

3x-5> 6x- 14

Taking one side negative that is mod

3x-5> -6x + 14

3x+ 6x > 14+5

9x> 19

x > 19/9

x > 2.11

so x lies between 2 and 3

3 > x > 2.11

Now putting the values for x= 19

3x-5> 6x- 14

57-5> 114-14

52 > 100 False

Now putting the values for x= 3

3x-5> 6x- 14

9-5> 18-14

4>4  False

Now putting the values for x= 2

3x-5> 6x- 14

6-5> 12-14

1> -2   True

There are 2 blue ribbons

HELP?? A lunch combo has the following options: Entree: Hamburger, Hotdog, Chicken sandwich Side: Apples, Salad Drink: Milk, Wat
murzikaleks [220]

Using the Fundamental Counting Theorem, the sample size of these outcomes is of 12.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

Considering the number of options for Entree, Side and Drink, the parameters are:

n1 = 3, n2 = 2, n3 = 2.

Hence the sample size of outcomes is:

N = 3 x 2 x 2 = 12.

Because it says it’s looking for the ESTIMATED sum. Round your answer to the nearest tenth, and that would be an estimated answer.
