First, subtract 7 on both sides so you can get the variable on one side:
40 = 2x + 7
-7 -7
33 = 2x
Now, divide both sides by 2 to isolate x:
33 = 2x
33/2 = x
Hope this helps!

There are 2 general steps to solving a linear equation of one variable:
1. add or subtract both segments with the same number so that it is expected that in one segment there are only variable modifiers or constant numbers 2. Change the equation into a simple form so that the coefficient of the variable is 1This can be done by dividing or multiplying by equal numbers
An equation will remain equivalent if both segments are multiplied or divided by the same number

Choose a number that satisfies both:
59
When divided by 3 it has a remainder of 2
When divided by 5 it has a remainder of 4.
There are 59 eggs in the basket.
Hope This Helps You!
Good Luck :)
The correct answer is:
59
Explanation:
The numbers between 50 and 60 that are divisible by 3 are
51, 54, 57, 60
The numbers between 50 and 60 that are divisible by 5 are
50, 55, 60
We know that when he counts by 3s, he has 2 left over; this means the number he counts to is 2 fewer than the number of eggs. This means, counting by 3s, we could have
51+2, 54+2, 57+2, or 60+2 = 53, 56, 59, 62
62 is not an option, since we know we have between 50 and 60 eggs; this gives us 53, 56 or 59.
We also know that when he counts by 5s, he has 4 left over; this means the number he counts to is 4 fewer than the number of eggs. This means, counting by 5s, we could have
50+4, 55+4, 60+4, or 54, 59, 64
64 is not an option, since we know we have between 50 and 60 eggs; this gives us 54 or 59.
The only number in both lists is 59, so this must be the answer.

Let's start off by writing an equation representing the sum of the interior angles of the given triangle.
y+79+37=180
Now, let's solve the equation for the variable 'y'.
y+79+37=180
Combine like terms:
y+116=180
Subtract 116 from both sides of the equation:
y+116-116=180-116
y=64
The measure of angle y is 64 degrees.

undistribute x

qx+1x=r
x(q+1)=r
divide both sides by (q+1)
[tex]x=\frac{r}{q+1}[/tex]
The value of x in the equation qx + x = r can be found by combining like terms and then isolating x. The solution is x = r / (q+1).
Explanation:The equation given is qx + x = r. This equation belongs to the domain of algebra and can be simplified using the principles of solving linear equations. Let's work step-by-step to evaluate the solution to this equation:
First, we can combine like terms on the left side, meaning we can add qx and x together since they are similar terms. By factoring out x, we get x(q + 1) = r. Then, in order to solve for x, we have to divide r by the sum of q + 1. The resulting equation is x = r / (q + 1).That is the solution to the equation.

A company sold 160 units in the last quarter of the year. Which of the following graphs represents the company's sales performance?
Answers
The question does not provide specific graphs to choose from for the company's sales performance. Nonetheless, a correct graph would show a point at 160 units for the last quarter of the year.
Explanation:Unfortunately, the question as presented does not include any graphs to choose from. Ideally, the correct graph would have the last quarter of the year on the x-axis and the number of units sold on the y-axis. It would display a single point at 160 units for the last quarter. However, without specific graphs to choose from, a more detailed answer cannot be provided.

The graph which represents the company's sales performance is graph B.
Which of the following graphs represents the company's sales performance?
The last quarter of the year begins October 1st and ends December 31st.
Total units sold by the company in the last quarter of the year = 160 units
Graph 1:
October = 40 units
November = 60 units
December = 40 units
Total = 140 units
Graph 2:
October = 40 units
November = 65 units
December = 55 units
Total = 160 units
Graph 3:
October = 40 units
November = 50 units
December = 50 units
Total = 140 units
Graph 4:
October = 40 units
November = 60 units
December = 50 units
Total = 150 units
Therefore, last quarter of the year in graph B represents the company's sales.

If x represents the width of a rectangle and if its length is twice its width how long is the rectangle
Answers
If x represents the width of a rectangle and if its length is twice its width then rectangle is 2x long.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given that x represents the width of a rectangle.
Length is twice its width
Length=2width
Length=2x
Length is nothing but how long the rectangle.
As the width of rectangle is x and length is 2x.
The area of rectangle is length times of width
Area of rectangle=Length×Width
=2x×x
=2x²
Hence, x represents the width of a rectangle and if its length is twice its width then rectangle is 2x long.
