Janet is three years older than her sister Julie.Janets brother is 8 years younger Than Her sister Julie .the sum of all of thei
slavikrds [6]

x + x + 3 + x - 8

3x - 5 = 55

3x = 60, x = 20

Since we put Julie as x, we put Janet at x + 3, and the brother is x - 8 (8 years younger)

Julie is 20

Janet (x + 3) = (20 + 3) = 23

Brother(x - 8) = (20 - 8) = 12

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.

steposvetlana [31]

Answer:

b = 3.1

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6
