Answer: n = 0
Step-by-step explanation:
Given expression
(-3/4) (8n + 12) = 3 (n - 3)
Expand parentheses and apply the distributive property
-6n - 9 = 3n - 9
Add 9 on both sides
-6n - 9 + 9 = 3n - 9 + 9
-6n = 3n
Subtract 3n on both sides
-6n - 3n = 3n - 3n
-9n = 0
Divide -9 on both sides
-9n / -9 = 0 / -9
[tex]\boxed{n=0}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
0
Step-by-step explanation:
-3/4(8n+12)=3(n-3)
-24/4n-36/4=3n-9
-6n-9=3n-9
-6n-3n-9=-9
-9n-9=-9
-9n=-9+9
-9n=0
n=0/-9
n=0

y^2+14y-5x+64=0
[tex] \hookrightarrow \: {y}^{2} + 14y - 5x + 64 = 0[/tex]
[tex] \hookrightarrow \: 5x = {y }^{2} + 14y + 64[/tex]
[tex] \hookrightarrow \: 5x = {y}^{2} + 14y + 49 + 15[/tex]
[tex] \hookrightarrow \: 5x = (y + 7) {}^{2} + 15[/tex]
[tex] \hookrightarrow \: x = \dfrac{(y + 7) {}^{2} + 15 }{5} [/tex]
[tex] \hookrightarrow \: x = \dfrac{1}{5} (y + 7) {}^{2} + 3[/tex]
therefore, the correct option is B
Answer:
x = (1/5)(y + 7)² + 3
Step-by-step explanation:
Given that,
→ y² + 14y - 5x + 64 = 0
Let's find the required solution,
→ y² + 14y - 5x + 64 = 0
→ 5x = y² + 14y + 64
→ 5x = y² +14y +49 + 15
→ 5x = (y + 7)² + 15
→ x = [(y + 7)² + 15]/5
→ [x = (1/5)(y + 7)² + 3]
Hence, it is the correct answer.

You have a box of tiles, each of which measures 6 by 10 inches. What is the least number of tiles you could use to form a square region? (Use this square to show how they would be arranged.) The prime factorizations of five numbers are given. Use them to find each of A and В
The least common multiple can be used to find the smallest square formed by equal sized shapes
The least number of tiles to be used is 15 tiles
The arrangement of the tiles, with the 6 inch side as base is 3 rows by 6 columns of tiles
The reason the above responses are correct is as follows:
The unit area of each square tile = 6 inches by 10 inches
Therefore, the area of the square obtained is a factor of 6 × 10 = 60 in.²
The side of the square have 6 and 10 as factors
The lowest common multiple of 6 and 10 is 30
Therefore, the smallest square has a side length of 30 inches and an area of 30 in. × 30 in. = 900 in.²
The least number of tiles = Area/(The area of each tile)
Therefore, the least number of tiles = 900 in.²/(60 in.²/tile) = 15 tiles
The least number of tiles = 15 tiles
The arrangement of the 15 tiles are as follows;
With the 6 inch width side as the base, five tiles are arranged along the base, three more rows are constructed using the same process to form the 30 inch by 30 inch square to give 3 rows by 6 columns of tiles

An angle measures 85.2° less than the measure of its complementary angle. What is the measure of each angle?
Answer:Complementary angles are two angles whose sum is 90 degrees.
Let x represent one of the angles.
The other angle which is 84.2 degrees less would be x - 84.2.
Using this, we can write an equation.
x + (x-84.2) = 90.
Combine like terms: 2x - 84.2 = 90
Add 84.2 to both sides of the equation.
2x = 174.2
Divide by 2: x = 87.1
and x - 84.2 would equal 2.9. to check: does 87.1 + 2.9 = 90? yes.

The ratio of cats to dogs at a pet store is 4:5 which means
Step-by-step explanation:
The ratio of cats to dogs at a pet store is 4:5. It means that if there are 4 cats in the store then there are 5 dogs, if there are 8 cats(4×2) there then there will be 10 dogs(5×2).
The number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The complete question is:
The ratio of cats to dogs is 4;5 if there are 20 dogs. How many cats are there?
It is given that:
The ratio of cats to dogs at a pet store is 4:5
Let 4x be the cats and 5x be the dogs
5x = 20
The above equation is a linear equation in one variable.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
x = 20/5
x = 4
Number of cats = 4x
Plug x = 4 in the above expression:
= 4(4)
= 16
Thus, the number of cats is 16 if the ratio of cats to dogs is 4:5 if there are 20 dogs.

The perimeter of an equilateral triangle is 3 (+ 5). The perimeter of a rectangle is 2 (2x - 3) + 2(2). If the perimeters of the two figures are equal, then what is the value of r?
Answer:
3.25
Step-by-step explanation:
Perimeter of triangle = 3(5) = 15 cm
Perimeter of rectangle = 2(2x - 3 + 4)
Perimeter = 2(2x + 1)
Perimeter = 4x + 2
4x + 2 = 15
4x = 15 - 2
4x = 13
x = 13/4
x = 3.25
DF= 78, DE = 5x -9, EF = 2x + 10, find DE.
Solve for x first.
5x - 9 + 2x + 10 = 78
7x + 1 = 78
7x = 78 - 1
7x = 77/7
x = 11
Then substitute the value of x to find DE.
DE = 5x - 9
5(11) - 9
55 - 9
DE = 46
Therefore, the value of DE is 46
DF= 78, DE = 5x -9, EF = 2x + 10, find DE.
Solution:First, solve for the value of x.
DE + EF = DF(5x - 9) + (2x + 10) = 787x + 1 = 787x = 78 - 17x = 77/7x = 11Then, plug and substitute the value of x to find the DE.
DE5x - 95(11) - 955 - 946Answer:The value of DE is 46Find the length of PQ if PQ = QR
Answer and Step-by-step explanation:
To find the length of PQ, we need to set the length of PQ equal to the length of QR (since in the question it tells us that PQ is equal to QR).
PQ = QR
x + 1 = 12
Solve for x.
Subtract 1 from both sides of the equation.
x + 1 - 1 = 12 - 1
x = 11
Now plug this number into the expression length for PQ.
11 + 1 = 12
The length of PQ is 12.
(you can also see that QR has a length of 12, so we can just say that PQ 12).
