The following are the ages (years) of 5 people in a room:
23, 14, 16, 21, 22
A person enters the room.
The mean age of the 6 people is now 24.
What is the age of the person who entered the room?
years

Answers

Answer - 48

We know that the new mean, divided by 6, must be 24. That means you have to multiply 24 by 6 to get 144. From 144, subtract the total age of the 5 people before (so 144 - 96). This gives the age of the new person, 48.

5) Solve: 2.4p + 6 = 48

Answers

Answer:

p = 17.5

Step-by-step explanation:

This is the answer because:

1) First, we have to isolate x

2) To isolate x, first -6 from +6 and 48

+6 - 6 = 0

48 - 6 = 42

Equation: 2.4p = 42

3) Now we are left with 2.4p = 42

4) Next, divide 2.4 from 2.4 and 42

2.4/2.4 = 0

42/2.4 = 17.5

5) We are left with

p = 17.5

Therefore, the answer is p = 17.5

HELP ME PLEASE

Answers

Answer:

14 & 15

Step-by-step explanation:

The area of the square is given by the equation: [tex]A = s^2[/tex] so therefore the length of the side is: [tex]s = \sqrt{A}[/tex].

So we take [tex]s = \sqrt{200} = 14.14[/tex]

Find the area and perimeter of a rectangle if the length is (x+7) and the width is (x+3).
