WHat is the property for 5x+10=24-2x
Final answer:
The correct solution to the equation 5x+10=24-2x is x=2, which is verified by substitution and results in an identity, confirming the solution is accurate.
Explanation:
The equation 5x+10=24-2x is a simple linear equation that can be solved by collecting like terms and isolating the variable x. Begin by adding 2x to both sides to get 7x + 10 = 24, then subtract 10 from both sides to obtain 7x = 14. Dividing both sides by 7 yields x = 2, which is the sole solution to the equation. Checking the solution, 24 - 2(2) does indeed equal 5(2) + 10, giving an identity of 20 = 20. This illustrates the solution is correct and verifies our process.

Susan and Abe shared comic books of 3 to 5. If Abe had 14 more comic books than Susan, how many comic books did they have in all?
Answer:
The number of comic books did they have in all = 56
Step-by-step explanation:
The ratio of comics with Susan : Abe = 3 : 5
Let us assume the common factor on this ratio = m
So, the number of comics Susan has = 3 m
The number of comics Abe has = 5 m
Also, given: Abe had 14 more comic books than Susan
So, the number of comics Abe had = 14 + 3 m
⇒ 5 m = 3 m + 14
or, 2 m = 14, or m = 7
So, the number of books Susan has = 3 m = 3 x 7 = 21 books
The number of books Abe has = 5 m = 5 x 7 = 35
So, the book they have in all = 21 + 35 = 56

Answer:
#2 486
#3 25
#4 25
#5 1,000,000
Step-by-step explanation:
Sequences like this always have some rule that determines the next number, a pattern that needs to be followed. Sometimes the pattern is easy to find, sometimes really hard.
#2 One of the first things to check is the ratio of adjacent numbers. Here we have 2 then 6 then 18 then 54 etc.
The most prominent feature of these numbers is that the next number is always three times bigger than the previous. It's safe to assume that the missing number will be 162 • 3 = 486.
#3 Of course numbers can be arranged in the decreasing order as well. However, that does not change their ratio. In this example, carefully examining, we can see that each number in the sequence is exactly twice smaller than the previous:
800 -> 400 -> 200 -> 100 etc.
Following this pattern, we can say that the next number will be 50 / 2 = 25.
#4 Of course, ratio is not the only way to help us find the pattern. One of the very often used methods is also the difference between adjacent numbers. Let's subtract each adjacent pair:
4 - 1 = 3
9 - 4 =5
16 - 9 = 7
Longer the sequence is, greater are the chances to see the pattern, but from this we could conclude that the difference between adjacent numbers is always an odd number (3, 5, 7). We could say that the next odd number is 9, so the missing number is 16 + 9 = 25
There is another pattern that could be found. This sequence could also represent the sequence of squared numbers:
1^2, 2°2, 3°2, 4^2
In this case, the next number would be 5^2 which is also 25.
#5 Again, we can find a pattern established on the ratio of numbers, but this time with repetitive symbol L. After every L, the number is a thousand times bigger than the previous number:
0.001 -> 1 -> 1000
So, following this pattern, the missing number would be 1000 • 1000 which equals to 1000000 (a million).
A flock of geese landed landed in a dog park. All the dogs ran to investigate. Alex counted
22 animals 64 legs. How many many geese and how many dogs did he count?
Answer:
12 geese
10 dogs
Step-by-step explanation:
We are given;
Total number of animals (dogs and geese) is 22 Total number of legs of animals is 64We are required to determine the number of geese and dogs that Alex counted;
We need to know that;
a dog has 4 legs while, a geese has 2 legs Therefore;Assuming he counted x number of geese and y number of dogs;
Then;
x + y = 22, and
2x + 4y = 64
Thus, solving the equation simultaneously;
we can multiply the first equation by 2, to get
2x + 2y = 44
2x + 4y = 64
Eliminating x (by subtracting the second eqn from the first eqn), we get;
-2y = -20
y = 10
Solving for x;
x = 22 - y
= 22 - 10
x = 12
Therefore; he counted 12 geese and 10 dogs

At the football game, 4 hamburgers and 6 soft drinks cost $34, and 4 hamburgers and 3 soft drinks cost $25. Which two equations can be used to determine the price of a hamburger and the price of a soft drink? Let x represent the cost of a hamburger and y represent the cost of a soft drink.
Answer:
[tex]4x+6y=34\\\\4x+3y=25[/tex]
Step-by-step explanation:
Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.
The cost of 4 hamburguers can be represented with this expression:
[tex]4x[/tex]
And the cost of 6 soft drinks can be represented with this expression:
[tex]6y[/tex]
Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:
[tex]4x+6y=34[/tex] [Equation 1]
The following expression represents the the cost of 3 soft drinks:
[tex]3y[/tex]
According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:
[tex]4x+3y=25[/tex] [Equation 2]
Therefore, the Equation 1 and the Equation 2 can be used to determine the price of a hamburger and the price of a soft drink
Suppose p represents the amount of air pressure in a tire and t, the time it takes for the tire to go flat, equals −8. What is the value of p, if the quotient of
p
t
is −4?
p = 32
Solution:
Given p represents the amount of air pressure in a tire.
t represents the time it takes for the tire to go flat and t = –8.
To find the value of p, if [tex]\frac{p}{t}=-4[/tex].
⇒ [tex]\frac{p}{t}=-4[/tex]
Substitute t = –8 in the above equation.
⇒ [tex]\frac{p}{-8}=-4[/tex]
Do cross multiply, we get
⇒ p = (–8) × (– 4)
⇒ p = 32
Hence, the value of p is 32 if the quotient [tex]\frac{p}{t}[/tex] is –4.
The image below represents a 12 x 16 room with an 8 x 10 piece of linoleum centered in the room . The yellow and blue rectangles extend the length of their respective sides. Where these two rectangles overlap, there is a green rectangle.
What is the area of the portion of the room shown in gray? _____ sq. ft.
The area of the gray portion in the room, after subtracting the area of the central linoleum from the total area of the room, is 112 sq. ft.
Explanation:To calculate the area of the gray portion in the room, first subtract the area of the linoleum from the total area of the room. The area of the room is given as 12 x 16 sq. ft. and the linoleum is 8 x 10 sq. ft.. To find the total area of the room, multiply the length by the width (12 x 16 = 192 sq. ft.). Then do the same for the linoleum (8 x 10 = 80 sq. ft.). Subtracting the area of the linoleum from the total area of the room gives us the gray area (192 - 80 = 112 sq. ft.). Hence, the area of the gray portion is 112 sq. ft.

If you are trying to find the equation of a line:
The equation of a line is y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]
Since you have m = -2, plug it into the equation
y = mx + b
y = -2x + b To find b, plug in the point they gave you (3, -7)
-7 = -2(3) + b
-7 = -6 + b Add 6 on both sides
-1 = b Now that you have b, plug it into the equation
y = -2x - 1

Explanation:Using Multiplication to Solve Division Problems
Miranda was asked to solve the problem 1300 divided by 26. To use multiplication to solve this division problem, she can apply the reciprocal approach. Essentially, she can multiply 1300 by the reciprocal (the inverse) of 26. The reciprocal of a number 'a' is 1/a, so the reciprocal of 26 is 1/26. However, finding the reciprocal of 26 directly can be challenging, so we can use intuitive steps that simplify the problem.
For example, we could productively think about what number, when multiplied by 26, gives us 1300. This is a form of inverse operations. One way to approach this is to break down 26 into factors like 2 and 13, which might lead to simpler multiples to work with. She may start by estimating and refining her estimations by multiplying different numbers by 26 and seeing how close she gets to 1300. It’s a trial and error process, but eventually, she will find the correct answer of 50, as 26 multiplied by 50 equals 1300.
