number 3.simplify 24cd/c
The answer is 24d because you have to simplify d_c first then you have 24c x d_c and then c cancels itself out so the answer is 24d.
Write an expression for the following a. One more than twice a number b. A number decreased by 6 c. Two-thirds of a number
a= 1+2b, b=1-6, c=2/3d. Hope this helps, I used D as a number in C you don't have to use d.
Solve each component inequality and graph the solution
[tex]x > 2 and \: x - 1 \leqslant 10[/tex]
Solution: The value of x after solving both components is [tex]2<x\leq11[/tex] or [tex](2,11][/tex].
Explanation:
From the first component it is clearly noticed that the value of x is greater than 2.
Simplify the second component.
[tex]x-1\leq 10\\x\leq 11[/tex]
From the above inequality it is clearly noticed that the value of x is less than or equal to 11.
Solving both components we get [tex]2<x\leq11[/tex] and the graphical representation is shown in the figure.
The red portion shows the solutions of [tex]x>2[/tex], blue portion shows the solution of [tex]x-1\leq 10[/tex] and purple portion which combination of red and blue portion shows the solution of both inequalities.
Therefore, value of x after solving both components is [tex]2<x\leq11[/tex] or [tex](2,11][/tex].

The answer using Pythagorean theorem
h^2 = b^2+p^2
21^2 = 17^2+x^2
441 = 289 + x^2
441-289 = x^2
122 = x^2
square root of 122 is x.
therefore, x= 11.04536102.
Answer: 12.32 is the answer.
Step-by-step explanation: Using the pythagorean thereom we can solve this by using the formula A^2+B^2=C^2.
We substitute in the values,
17^2+B^2=21^2.
Now we simplify.
289+B^2=441
We subtract the 289 from both sides,
B^2=152
Now we use square root to find the answer.
12.32 is the answer.

Find the perimeter of the parallelogram whose vertices are at (-2, 0), (0, -2), (2, 0), and (0, 2).
The perimeter of the parallelogram is 8√2.
In order to find this, we need to find the length between any of the points. You'll notice that you can create a right triangle between each set of consecutive points. As a result, you can draw the legs and use the Pythagorean Theorem. In each case, the legs will equal 2. So we find the length of the side as
Leg^2 + Leg^2 = Side^2
2^2 + 2^2 = s^2
4 + 4 = s^2
8 = s^2
√8 = s
2√2 =s
Now to find the perimeter, we multiply this length by 4.
4 * 2√2 = 8√2
The perimeter of the parallelogram with vertices at (-2, 0), (0, -2), (2, 0), and (0, 2) is 8sqrt2 units.
Explanation:In order to find the perimeter of the parallelogram with vertices at (-2, 0), (0, -2), (2, 0), and (0, 2), you firstly need to calculate the distances between the vertices to determine the lengths of the sides. The formula to find the distance between two points (x1, y1) and (x2, y2) on a graph is given by sqrt((x2-x1)² + (y2-y1)²). If we apply this formula to our coordinates, we find that the lengths of the sides of the parallelogram are sqrt((0-(-2))² + (-2-0)²)) = 2sqrt2 and sqrt((2-0)² + (0-(-2))²)) = 2sqrt2. Since a parallelogram has two pairs of equal sides, we know that the four sides will have the same length. Therefore, the perimeter of the parallelogram is 4 * 2sqrt2 = 8sqrt2 units.

Select all the possible solutions for 2x +7 < 3x-5
Solution :
We have to find all the possible solutions for the inequality [tex]2x+7<3x-5[/tex].
The given inequality can be solved as,
Subtracting 7 from both side , we get
[tex]2x+7-7 < 3x-5-7\\\\\Rightarrow 2x<3x-12[/tex]
Now, Subtracting 3x from both side, we get
[tex]2x-3x<3x-12-3x\\\Rightarrow -x <-12\\[/tex]
As we here we can see that both sides have similar sign, so we can cancel them out.
[tex]\Rightarrow x < 12[/tex]
Hence, the possible solution of the inequality [tex]2x+7<3x-5[/tex] is [tex]x< 12[/tex]
how to determine if its a proportional
You have to see if they are all moving up at a constant rate. You can check this by subtracting $17.40 from $21.75. It is $4.35. Then multiply $4.35 by 46. If it is not equal to $200.10, then it is not a proportional relationship. When you multiply it, you actually do get $200.1, which is equal to $200.10. So this is a proportional relationship.
The difference between two numbers is 15. If 8 is added to twice the greater number, the result is 4 less than 3 times the lesser number. Find the two numbers.
x - y = 15
2x + 8 = 3y - 4
Using the first equation, we can get an approximate value for x.
x = 15 + y
Now that we have a value for x, we can replace it in the second equation to find the value of y.
2(15 + y) + 8 = 3y - 4
Distributive property.
30 + 2y + 8 = 3y - 4
Combine like terms.
38 + 2y = 3y - 4
Subtract 2y from both sides.
38 = y - 4
Add 4 to both sides.
y = 42
Now that we have the value of y, we can find the value of x.
x - 42 = 15
Add 42 to both sides.
x = 57

Solve 24 - 3 x = -27
Answer,
X = 17Explanation,
Step 1: Simplify both sides of the equation
24 − 3x = −27
24 + −3x = −27
−3x + 24 = −27
Step 2: Subtract 24 from both sides.
−3x + 24 − 24 = −27 − 24
−3x = −51
Step 3: Divide both sides by -3.
-3x/-3 = -51/-3
X = 17

Use the substitution method to solve the system of equations. Choose the correct ordered pair. 3x-y=3 y=2x+2
We have been given that
3x - y = 3 and
y = 2x + 2
Substitute y = 2x + 2 in the first equation, we get,
3x - (2x + 2) = 3
3x - 2x - 2 = 3
x - 2 = 3
x = 5
y = 2x + 2
= 2(5) + 2
= 12
Hence, the solution is (5, 12).

Answer: A
Step-by-step explanation:
Let us first observe behavior in only quadrant 1 .
On x-axis one small box represent one year.
On y-axis one small box represent one dollar.
If we see the 1 year on x-axis its corresponding value of dollar on y -axis is in mid of 4 dollars and 5 dollars.
Now if we see the 2nd year on x-axis its corresponding value of dollar on y-axis is at 6 dollars .
It concluded that after each year 0.5 dollars per pound increases.
We can see the same behavior throughout the straight line.
Which proportion correctly shows the equivalence of two ratios?
A. 2:3=27:18
B. 14:35=7:2
C. 4:5=32:40
D. 13:39=6:2
C. 4:5=32:40 is your answer
Treat each ratio like fractions. Note the equal sign. This means that, when each fraction is simplified, they would be the same.
4/5 = 4/5
(32/40)/(8/8) = 4/5
4/5 = 4/5
∴ (C) is your answer

The sum of 4 times a number and 7 is equal to 5
The question presents a basic algebraic problem. We translate the words into a mathematical equation, 4x + 7 = 5. After some simple manipulations (subtracting 7 from both sides and dividing the result by 4), we find that the value of x is -0.5.
Explanation:The question presents a typical example of a simple equation in Mathematics. The first step in solving this problem involves interpretation. The statement 'The sum of 4 times a number and 7 is equal to 5' can be translated into this equation: 4x + 7 = 5. To obtain the value of x, we need to isolate it on one side of the equation.
We can proceed by subtracting 7 from both sides
to achieve 4x = -2. Finally, we divide both sides of the equation by 4 to obtain x = -0.5. Thus, the number in question is -0.5.
