Answer:
100 + 50m = 250
50m = 250 - 100
50m/50 = 150/50
m = 3

The mean age of 5 people in a room is 31 years.
A person enters the room.
The mean age is now 30.
What is the age of the person who entered the room?
Answer:
25 year
Step-by-step explanation:
Mean = sum/no. *of observations
Initially, number of people = 5 & let the sum of their ages be S.
=> 31 = S/5
=> 155 = S
When one more entered, number = 6. Let his age be 'a'.
Sum of ages = S + a = 155 + a
=> 30 = (155 + a)/6
=> 180 = 155 + a
=> 25 = a
Do u want branlist answer this please
Answer:b
Step-by-step explanation:
a line always has 180 degrees so u just subtract 180-85=95 or what ever the angle is
What is the slope of this line?
2/3 1/3 -1/3 -2/3
Answer:
2/3
Step-by-step explanation:
Two points on this line are (0, -3) and (6, 1).
Going from the first to the second, we see a change in x of 6 units and a change in y of 4 units. The slope of the line is thus m = rise / run = 4/6 = 2/3
The value of y varies inversely with x, and y=-2 when x=4

Which property is being demonstrated?
quotient of powers property
power of a product property
product of powers property
power of a quotient property
Answer:
A.
Step-by-step explanation:
We see a fraction. A fraction means a division, and the result of a division is called a quotient. We know we have a quotient.
We have two choices with "quotient."
A. quotient of powers property
D. quotient of powers property
We need to choose A or D.
A. quotient of powers means a division of powers. That is what we see with the fraction. A power in the numerator, and a power in the denominator. We have a division of powers, so it is a quotient of powers.
D. power of a quotient. This is take a fraction which is a quotient, and raise the entire fraction to an exponent. This is not what we have.
Answer: A.

Given the system of equations, what is the value of the system determinant?
2x + y = 8
x - y = 10
0-1
0-2
0-3
Given:
The system of equation is
[tex]2x+y=8[/tex]
[tex]x-y=10[/tex]
To find:
The value of the system determinant.
Solution:
If two equations of a system of equations are [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex], then the system determinant is
[tex]D=\left|\begin{matrix}a_1&b_1\\a_2&b_2\end{matrix}\right|[/tex]
[tex]D=a_1b_2-b_1a_2[/tex]
The given two equations are [tex]2x+y=8[/tex] and [tex]x-y=10[/tex].
Here, [tex]a_1=2,b_1=1,c_1=8, a_2=1,b_2=-1,c_2=10[/tex].
[tex]D=\left|\begin{matrix}2&1\\1&-1\end{matrix}\right|[/tex]
[tex]D=(2)(-1)-(1)(1)[/tex]
[tex]D=-2-1[/tex]
[tex]D=-3[/tex]
The value of the system determinant is -3. Therefore, the correct option is C.
Answer:
-3

2x+y=21;y=-2x+21
please hurry I need this straight away
Step-by-step explanation:
2x + y = 21
Solving
2x + y = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
2x + y + -1y = 21 + -1y
Combine like terms: y + -1y = 0
2x + 0 = 21 + -1y
2x = 21 + -1y
Divide each side by '2'.
x = 10.5 + -0.5y
Simplifying
x = 10.5 + -0.5y
Find the simple Interest
I=?
P=$1300
R= 5%
T=6 years
$390
$1690
O $39000
Answer:
Step-by-step explanation:
P =$ 1300
R = 5% = 0.05
T = 6 years
I = P * R *T
= 1300 * 0.05 * 6
= $ 390
