2(12+x) = 2x=24 simplify and show work
Answer:
No possible answer (unless the equal sign was supposed to be a plus sign, then see answer below)
Step-by-step explanation:
we can simplify the expression like such:
24 + 2x = 2x = 24
As you will notice 2x + 24 cannot equal 2x, or 24.
If the equals sign was a typo and was meant to be a plus sign then the answer is all real numbers.
2(12 + x) can be broken down to (2*12) + (2*x) which equals 2x + 24.
Then this equals the other side of the equation meaning that it doesn't matter what x equals the equation is always equal.
16.4,1.64,1.6,16.099 greatest to least
Answer:
1.6, 1.64, 16.099, 16.4
Step-by-step explanation:
Add a 0.
1.60, 1.64, 16.099, 16.40
The ones are of lesser value because they only have one whole number, and the 16.099 is less than 16.40 because it has that 0 in front of the nines.
Sorry, I'm not the best at explaining.

45 Points!! ASAP 1 QUESTIONS NEED HELP WITH PROBABILITY, NO SPAMS OR LINKS!!! THE FORMULA FOR THE AREA OF A CIRCLE IS ∏ R^2
Answer:
3.2%
Step-by-step explanation:
You want to find the area of the hole and the area of the board. The area of the board is 21x42 which is 882 inches squared. The circular hole has a radius of 3 inches so [tex]\pi[/tex]3² which is 9[tex]\pi[/tex].
Now put in calculator [tex]\frac{9\pi }{882}[/tex] which is pi over 98 which simplifies to 0.032.

what two numbers multiply 25 and add 26
Let's set our two numbers as x and y:
When two numbers multiply 25 --> xy = 25
Add to 26 --> x + y =26
The equations:
xy = 25 <-- equation 1x + y = 26 <-- equation 2Now Solve:
Solve for y in the equation 2:
y = 26 - x <-- equation 3
Plug equation 3's value of y into equation 1
x(26 - x) = 25
-x^2 + 26x - 25= 0
x^2 - 26x + 25 = 0
(x - 1) (x -25) = 0
Thus say x = 1, then y = 25, it can be either way that x = 25 and y = 1, but our two numbers are 1 and 25
Hope that helps!

-0.4(x+3)=4 answer this problem
Answer:
x = - 13
Step-by-step explanation:
- 0.4(x + 3) = 4 ( divide both sides by - 0.4 )
x + 3 = - 10 ( subtract 3 from both sides )
x = - 13

Answer: The area of the shaded region is 30 cm^2
Step-by-step explanation:
First, we recall the area for a rectangle and a triangle.
-Area for rectangle: A = L x W
-Area for triangle: A = 1/2 x b*h
Next, I find the area of the total region.
-12 cm x 4 cm = 48 cm^2
Then, I find the area for the non-shaded region (or the white triangle)
- A= 1/2 x 9*4
- A= 1/2 x 36
- A = 18 cm^2
Finally, I subtract the total area of the whole region from the non-shaded region ( or again white triangle)
- 48 minus 18 = 30 cm ^2
5(m+2)-m=2m+3
Please I need help
Answer:
m=-7/2
Step-by-step explanation:
(5 • (m + 2) - m) - (2m + 3) = 0
2m + 7 = 0
3.1 Solve : 2m+7 = 0
Subtract 7 from both sides of the equation :
2m = -7
Divide both sides of the equation by 2:
m = -7/2 = -3.500
Answer
5(m+2)-m=2m+3
5m+10-m=2m+3
5m-2m-m=-10+3
3m-m=-10+3
2m=-7
m= -7/2
m= -3.5

I need help with this question
Answer:
h = 16°
Step-by-step explanation:
The total angle of a straight line = 180°.
So we can say that 151° + x = 180°
180° - 151° = x
x = 29°
total angles of a triangle = 180°
∴ 118 + 29 + 2h + 1 = 180
⇒ 148° + 2h = 180°
⇒ 2h = 180° - 148°
⇒2h = 32°
⇒h = 32° ÷ 2
⇒ h = 16°

The following table provides a probability distribution for the random variable y. Y f(y) 1 0. 20 5 0. 30 6 0. 40 9 0. 10 (a) compute e(y). If required, round your answer to one decimal place.
The expected value of y, rounded to one decimal place, is 5.0.
Here, we have to compute the expected value E(y), we multiply each value of y by its corresponding probability and sum them up.
E(y) = (1 * 0.20) + (5 * 0.30) + (6 * 0.40) + (9 * 0.10)
Calculating the above expression:
E(y) = 0.20 + 1.50 + 2.40 + 0.90
E(y) = 5
Therefore, the expected value of y, rounded to one decimal place, is 5.0.
The expected value of a discrete random variable can be calculated as the weighted average of all its possible values, with the weights being the probabilities of each value.
In order to calculate the expected value, we will need to multiply each value by its corresponding probability and then add up these products:
E(y) = 1 (0.20) + 5(0.30) + 6 (0.40) + 9(0.10)
E(y) = 0.20 + 1.50 + 2.40 + 0.90
E(y) = 5
Therefore, the expected value of y is 5.
