[tex] \\ [/tex]
[tex] \huge \purple{ \frac{3x - 1}{5} - \frac{x}{7} = 3}[/tex]
Answer:
x = 7
Step-by-step explanation:
[tex]\frac{3x-1}{5}[/tex] - [tex]\frac{x}{7}[/tex] = 3
Multiply through by 35 ( the LCM of 5 and 7 ) to clear the fractions
7(3x - 1) - 5x = 105 ← distribute parenthesis and simplify left side
21x - 7 - 5x = 105
16x - 7 = 105 ( add 7 to both sides )
16x = 112 ( divide both sides by 16 )
x = 7
To verify the answer substitute x = 7 into the left side of the equation and if equal to the right side then it is the solution
[tex]\frac{3(7)-1}{5}[/tex] - [tex]\frac{7}{7}[/tex]
= [tex]\frac{21-1}{5}[/tex] - 1
= [tex]\frac{20}{5}[/tex] - 1
= 4 - 1
= 3 = right side
Then x = 7 is the solution to the equation

Answer:
159
Step-by-step explanation:
10^2+(3+5)^2-5
First do the parentheses: 3+5 is 8
Now the equation is
10^2+8^2-5
Exponents:
10^2 is 100
8^2 is 64
100+64-5
Simplify and you would get 159
Thus the answer is 159
Hope this helps!
First thing we want to know is what it is asking us.
So, it is asking us to evaluate this expression. Which means to find the answer to it.
Second thing is the order of Operations.
P- (Parentheses)
E-Exponents
M Multiplication
D Division
A Add
S Sub
Now that we know what that means, we may now solve it.
you see a parenthesis, right? Do what is inside first
1.3+5=8
Now there is a exponent by the parentheses. We do that next
(Exponent means we times that number by the number. Like 4 to the power of 3 is really just 4x4x4)
2.8 to the power of 2 is 8x8 which is 64.
So, we got 64 down let's see our equation now.
10^2+64-5
Now, the next step in PEMDAS Is to do the exponents. 10 to the power of 2 is really just 10x10.
(A trick is that if you see the little number beside the 10, it means how many zeros there are like 10to the power of 2 is 100)
So, our new equation is
100+64-5.
Now all we have to do it add and sub right to left
100+64=164
Our new equation is 164-5 which is 159.
I hope this helps! If it's wrong blame me..
Clare wants to buy a used wide-screen TV that sells for $2,000 cash. She will make a down payment of $1,000 and then six monthly payments of $200. What is the full installment price and the annual interest rate ?
The full installment price is $ 2200, and the annual interest rate is 10%.
Since Clare wants to buy a used wide-screen TV that sells for $ 2,000 cash, and she will make a down payment of $ 1,000 and then six monthly payments of $ 200, to determine what is the full installment price and the annual interest rate is due perform the following calculation:
1000 + 200 x 6 = 1000 + 1200 = 2200 1000 = 100 1200 = 120 20/12 x 6 = 10
Therefore, the full installment price is $ 2200, and the annual interest rate is 10%.

you need to prepare 50 portions of broccoli flowers. A prepared portion weighs 0.090kg. Trimmings account for 25% of the total weight. How much broccoli do you need to order ?
The amount of broccoli needed to be ordered to prepare 50 portion of broccoli flower is 3.375 kg.
You need to prepare 50 portions of broccoli flowers.
A prepared portion weighs 0.090 kg.
Trimming accounts for 25% of the total weight.
Therefore, to find how much broccoli is needed to order can be calculated as follows:
Trimming account for 25% of 0.090 = 0.0225 kg The remaining weight(broccoli) required = 0.090 - 0.0225 = 0.0675 kgTherefore,
the broccoli needed to be ordered = 0.0675 × 50 = 3.375 kg

A car is 200 inches long the truck is 50% longer than the car how long is the truck
Answer:
300
Step-by-step explanation:
This question is pretty simple.
First, we just have to find 50% of 200.
So 50% is also 1/2.
1/2 of 200 is just 100. The question says that the truck is 50% LONGER than the car.
So 50% longer is 100 and 100+200(the length of the car) is 300.
The answer.

Triangle ABC is rotated clockwise about the origin through 90°. The resulting triangle is then
rotated clockwise about the origin through 270° Identify the vertices of the triangle after
these transformations
When a shape is rotated, it must be rotated through a point.
The vertices of the triangle would remain unchanged after both transformations
Assume the coordinates of triangle ABC is (x,y).
The first rotation is 90 degrees clockwise rotation.
The rule of this transformation is:
[tex](x,y) \to (y,-x)[/tex]
Next, the triangle is rotated 270 degrees clockwise.
The rule of this transformation is:
[tex](x,y) \to (-y,x)[/tex]
So, we have:
[tex](y,-x) \to (x,y)[/tex]
Hence, the vertices of the triangle would remain unchanged after both transformations

Julia wants to make a vegetable garden in her backyard for 6 different vegetables. She makes 6 sections in the
garden. The dimensions of the garden are 3 sections long by 2 sections wide. Each section is in the shape of a
square. The area of the vegetable garden is 73.5 square feet. What is the length of the vegetable garden?
Answer:
36.75 square feet
Step-by-step explanation:
First, we can divide 73.5 into 6 to calculate area for each section. We get the answer of 12.25. Next, it says that the garden is 3x2 sections, so we multiply 12.25 by 3 to get a total of 36.75
The Julia wants to make a vegetable garden in her backyard length of the vegetable garden is 10.5 feet.
The garden is divided into 6 sections.
The dimensions of the garden are 3 sections long by 2 sections wide.
Each section is in the shape of a square.
The area of the vegetable garden is 73.5 square feet.
Let's denote the side length of each square section as "s". Since there are 6 sections, the area of the vegetable garden can be calculated as:
Total Area = Number of Sections × Area of One Section
73.5 = 6 × s²
Now, solve for the side length "s":
s² = 73.5 / 6
s² = 12.25
Taking the square root of both sides:
s = √12.25
s = 3.5 feet
Since each section is a square and has a side length of 3.5 feet, the dimensions of the garden are 3 sections long by 2 sections wide, which translates to:
Length = 3.5 feet/section ×3 sections = 10.5 feet
