the mean of 4 8 9 x and 2x is 6 calculate the value of x
Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3

Answer:
2 years
Step-by-step explanation:
5%× 600= $30
$30×2=$60
not sure if you will get what I mean but that's how I worked it out.
Answer:
[tex]I = \frac{PRT}{100}[/tex]
P= $600
R= 5%
[tex]I = \frac{600 \times \ 5 \times T}{100} = 30T\\\\[/tex]
A = double the deposit =2 600= $1200
[tex]A = I + P \\1200 = 30T + 600\\30T = 600\\T = 20[/tex]

If 8 boxes of cereal cost $27.60, what is the price of one box?
Answer:
$3.45
Step-by-step explanation:
Let "x" repreesnt the cost of one box. If 8 = 27.60, 1 = "x". Set up a fraction, then solve;
[tex]\frac{8}{27.6}=\frac{1}{x}[/tex]
Step 1: Divide 27.6 by 8
[tex]27.60 \div 8 = 3.45[/tex]
Step 2: Multiply the result by 1
[tex]3.45 \times 1 = 3.45[/tex]
That means 1 cereal box costs 3.45 dollars.
The area of a rectangle is represented by the expression 2x2 + 10x + 12. Daniel is convinced that the dimensions of this rectangle could be (2x + 4) and (x + 3) or (x + 2) and (2x + 6). Do you agree or disagree with Daniel? Use words to justify your opinion.
Answer:
I agree with daniel
Step-by-step explanation:
Given the area of a rectangle expressed as;
A(x) = 2x²+10x+12
On factorizing;
A(x) = 2x²+6x+4x+12
A(x) = 2x(x+3)+4(x+3)
A(x) = (x+3)(2x+4)
since A(x) = l(x)w(x)
Hence the legnth and width of the rectangle are 2x+4 and x+3.
Also A(x) = 2x²+6x+4x+12 can be factorized as;
A(x) = 2x²+4x+6x+12
A(x) = 2x(x+2) + 6(x+2)
A(x) = 2x+6(x+2)
Therefore I agree with Daniel. The factor differs due to the difference in arrangement of 4x and 6x in the expression. Precedence of values affects the final factors

Answer:
y = 5/4 x + 9
y = -5x+4
Step-by-step explanation:
a)The equation of the line in slope intercept form is expressed as y = mx+b
m is the slope
b is the intercept
Given
Slope m = 5/4
y-intercpet = 9
Substitute
y = mx+b
y = 5/4 x + 9
b) Given the coordinates (0,4) and (2, -6)
Slope m = -6-4/2-0
m = -10/2
m = -5
Since the y intercept of the line is (0, 4), hence b = 4
Get the equation
Recall
y = mx+b
y = -5x +4
This gives the required equation

Dividing by 0.30, we find ...
x = 27/0.30 = 90
Then ...
30% of 90 = 27
Are 4(a - 3) and 4a - 7 equivalent expressions?
Answer:
Yes
Step-by-step explanation:
Given expression: 3x+9
Take 3 outside from the expression, we get,
= 3(x+3), which is called the equivalent expression
Answer:
No
Step-by-step
We have to multiply the 4 by both the a and the 3 since there a parenthesis around them. This would of course be distributive property. Since you don't know what a is, it would just be 4a and since we can multiply 4 and 3 that would be 12. So, 4(a - 3) is equivalent to 4a - 12.

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Money is invested in a saving account at 12% simple interest.
And, After one year there is $1680 in the account.
Now,
Let the original invested amount = x
So, We can formulate;
⇒ x + 12% of x = 1680
⇒ x + 12x/100 = 1680
⇒ 112x = 1680 × 100
⇒ 112x = 1,68,000
⇒ x = 1,68,000/112
⇒ x = $1,500
Thus, The original invested amount = $1,500

Answer:
80 in^3
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base, and h is the height of the pyramid. Here, h=8 in.
__
Here, the base is a triangle. The formula for its area is ...
A = 1/2bh
where b is the base segment of the triangle, and h is the height of the triangle perpendicular to the base segment. Here, b=10 in, and h = 6 in.
The triangular base area is ...
A = 1/2(10 in)(6 in) = 30 in^2 . . . . base area "B"
__
Using the above base area and pyramid height, we find the volume of the pyramid is ...
V = 1/3(30 in^2)(8 in) = 80 in^3
The volume of the pyramid is 80 cubic inches.
