8n+4-6n/2
8n+4-3n
5n+4
Answer:
n+2
Step-by-step explanation:
to simplify this expression 8n+4-6n/2
we have,
{8n-6n + 4}/2
{2n + 4}/2
to further simplify this expression {2n + 4}/2 , we are going to factorize 2 from the numerator ,
we have
=2(n +2)/2
the next step to simplify the 2(n +2)/2 further is to use the factorised 2 at the numerator to divide the 2 at the denominator so that we can have a simplified expression.
we have
=2(n +2)/2
=n+2
therefore the simplified form of the expression 8n+4-6n/2 is n+2
What is the answer to 1.5=0.6(w+0.4)
Answer:
W= 2.1
Step-by-step explanation:
The solution to the equation 1.5 = 0.6( w + 0.4 ) is w = 2.1.
What is the solution to the given equation?Given the equation in the question:
1.5 = 0.6( w + 0.4 )
To solve the equation 1.5 = 0.6(w + 0.4) for "w," first apply distributive property:
1.5 = 0.6( w + 0.4 )
Distribute 0.6 on the right side of the equation:
1.5 = 0.6(w) + 0.6(0.4)
Simplifying, we get:
1.5 = 0.6w + 0.24
Subtract 0.24 from both sides of the equation:
1.5 - 0.24 = 0.6w + 0.24 - 0.24
1.5 - 0.24 = 0.6w
1.26 = 0.6w
0.6w = 1.26
To solve for "w", divide both sides by 0.6:
0.6w / 0.6 = 1.26 / 0.6
w = 1.26 / 0.6
w = 2.1
Therefore, the value of w is 2.1.

Find the equation of a line that passes through the point
(0,7) with a slope that is the opposite of the slope of the
line with equation y = -x -5.
Answer:
y=x+7
Step-by-step explanation:
y-7=1(x-0)
y-7=x-0
y=x+7
Answer:
y=x+7
Step-by-step explanation:
You need a slope that is opposite the slope of equation y=-x-5. To do this you need to find the opposite reciprocal. For -1, the opposite reciprocal would be 1. So, your slope is going to be 1.
You need the line to pass through (0,7), which is a point on the y axis. b in y=mx+b is the y-intercept. So, you would make 7 your b.
By plugging in these numbers you end up with y = x + 7

6. A triangular sail has a base length of 2.5 meters. The area of the sail
is 3.75 square meters. How tall is the sail?
Answer:
3 meters
Step-by-step explanation:
Area of a Triangle
= 1/2 x b x h
Given
Base Length b = 2.5 meters
Area = 3.75 square meters
Height h = ?
Therefore
3.75 = 1/2 x 2.5 x h
3.75 = 2.5/2 x h
3.75 = 1.25 x h
Divide both sides by 1.25
3.75/1.25 = 1.25/1.25 x h
3 = h
h = 3 meters
The sail is 3 meters tall
solve the equation 4x — 3y = y —12 for x if y is 6. Make sure to first solve the equation for x in terms of y. X= ________
Answer:
x = 3
Step-by-step explanation:
4x - 3y = y - 12
If y = 6
4x - 3 x 6 = 6 - 12
4x -18 = -6
Add 18 to both sides
4x - 18 + 18 = -6 + 18
4x = 12
Divide both sides by 4
x = 12/4
x = 3

And ∠APE is a right angle ⇒ ∠APE = 90°
So, BE⊥AD
And so, ∠BPE = 90° ⇒(1)
But it is given: ∠BPE = (33k-9)° ⇒(2)

Can someone explain this?
Answer:
First, you know that a triangle has 180° total. So, you take 180-38-25 and that equals 117. So the corner inside the triangle is 117. So a straight line is also equal to 180. You take 180-117 and that is 63. 4x+3 = 63. You subtract 3 from both sides and get 4x = 60. To get x by itself you divide by 4 and x = 15.

Answer:
4
Step-by-step explanation:
5.728 rounds up to 6 because it is greater than 5.50 and 2.317 rounds down to 2 since it is less than 2.5. 6 - 2 = 4.
Final answer:
To estimate the difference between 5.758 and 2.317, you round 5.758 up to 6 and 2.317 down to 2, and then subtract to get an estimated difference of 4.
Explanation:
The student is asking how to estimate the difference between two numbers by rounding them to the nearest whole number before subtracting.
To estimate the difference between 5.758 and 2.317, we first round each number to the nearest whole number:
5.758 rounds up to 6 because the first digit after the decimal (7) is greater than 5.
2.317 rounds down to 2 because the first digit after the decimal (3) is less than 5.
After rounding the numbers, we perform the subtraction:
6 - 2 = 4
Therefore, the estimated difference is 4.

Mr. Thompson got some money for his birthday He spent 1/5 of it on dog treats. Then, he divided the remainder among his 3 favorite charities.
If he donated $60 to each charity, how much money did he receive for his birthday?
Answer:
$225 of birthday money
Step-by-step explanation:
he spent 20 percent (1/5) of the money on dog treats, and the remaining 80 percent (4/5) went to 3 different charities. If $60 dollars were given to each charity, that means a total of $180 dollars was given to charity. if 4/5 of the money is equal to $180, we can divide 180 by 4 to get $45 dollars. this means that 1/5 of the birthday money would be equal to $45 dollars. so to find 5/5, or 100% of the money, simply multiply $45 by the denominator, 5, to get the answer. the total birthday money received was $225 dollars, and $45 dollars of that was used for dog treats.
The amount of money Mr. Thompson received for his birthday, work backwards from how much he donated to charities after spending 1/5 on dog treats, resulting in $300.
To find out how much money Mr. Thompson received for his birthday, we will work backwards from the information given.
Let's assume he received x amount of money for his birthday.
He spent 1/5 of it on dog treats, so he spent (1/5)x on dog treats.
The remainder after buying the dog treats is (4/5)x.
Since he divided this among 3 charities, each charity received $60, so [tex](\frac{4}{5} )x = 3*60.[/tex]
Solving this equation, we find x = $300.
Hence, Mr. Thompson received $300 for his birthday.
The width of a rectangle is 4x - 4.25 feet and the length is 7x + 7 feet. Write and
expression to find the perimeter of the rectangle.
Perimeter is 2l+2w in the case of a rectangle, so you would write:
2(4x - 4.25) + 2(7x +7)
Answer: The expression can be written as Perimeter = 22x + 5.5
Step-by-step explanation: The perimeter of a rectangle is given as 2(L + W), where L is the length and W is the width. In the question, the length L has been given as 7x + 7 while the width W has been given as 4x - 4.25.
Inserting the values of the length and the width, the perimeter can now be properly written as,
Perimeter = 2(L + W)
Perimeter = 2( {7x + 7} + {4x - 4.25} )
By collecting like terms we now have
Perimeter = 2(11x + 2.75)
Perimeter = 22x + 5.5

The 1 copy makes the cost equivalent in two options and the cost of 1 copy is $41.
Step-by-step explanation:
The given information are that,
Elsa could use a printer in which it cost a $38 setup fee and $3 for each copy.
Elsa could go to a supply store in which it cost $36 up-front fee and $5 for each copy.
To find the same amount for certain number of copies in both the cases :
Let us assume that the number of copies be 'x'.
In the first case, the total cost will be = setup fee + cost for x copies.
⇒ Total cost = 38 + 3x
In the second case, the total cost will be = up-front fee + cost for x copies.
⇒ Total cost = 36 + 5x
To find the x value :
Equating the total cost of both the cases, we get
⇒ 38 + 3x = 36 + 5x
⇒ 38-36 = 5x-3x
⇒ 2 = 2x
⇒ x = 1 copy
Therefore, taking 1 copy make the two options equivalent in terms of cost.
The cost of 1 copy = 38+ 3(1) = 41 dollars.
Therefore, it would cost $41 for 1 copy.

The length of a rectangular state park is 2 miles longer than twice the width. The area of the park is 84 square miles. What is the width of the park?
Answer:
Step-by-step explanation:
hello : look this solution
Final answer:
To find the width of a rectangular state park with an area of 84 square miles where the length is 2 miles longer than twice the width, we set up a quadratic equation and solve for the width. The width of the park is 6 miles.
Explanation:
The question involves solving a quadratic equation to find the width of a rectangular state park where the length is 2 miles longer than twice its width, and the area is 84 square miles. To solve this problem, let's let w represent the width of the park.
According to the problem, the length l can be expressed as:
l = 2w + 2
The area A of a rectangle is given by the formula:
A = l × w
Substituting the given area and the expression for the length, we have:
84 = (w)(2w + 2)
Which simplifies to:
84 = 2w² + 2w
And further simplifies to:
0 = 2w² + 2w - 84
Dividing the entire equation by 2 to simplify:
0 = w² + w - 42
Now, we solve this quadratic equation for w, the width of the park. Using the quadratic formula or factoring (if possible), we find the positive value of w, which could be the width of the park since a width can't be negative:
w = 6
So, the width of the park is 6 miles.
