8
Answer:
6
Step-by-step explanation:
(8/3) / (-4/9)
when dividing fractions you use the acronym k.c.f (keep change flip)
keep the first fraction
change the operation (divide to multiply)
flip the other fraction
(8/-3) x (9/4)
after re-writing your expression, you want to solve
do this by multiplying both numerators by each other and same with the denominators
(-8x9) / (3x-4)
then you get a new fraction,
-72/-12
simplify,
-72/-12 = 6 (multiplying/dividing 2 negatives will always give you a positive)

Find the x
Answer:
X=9
Step-by-step explanation:
We want to first understand that a triangle will always be 180°. Next, we want to look at both where 25° and 12x-3 are. If we look closely we can see that they are the vertical angles of the interior angles of the triangle. To solve this algebraically we have to basically add all the angles (including 12x-3) to solve for x.
Adding all the angles together would look like this: 25+50+12x-3. Next, add up all like terms to get 12x+72=180. You want to get x by itself by subtracting by 72 on both sides to get 12x=108. Isolate x by dividing by 12 on each side which results in x=9

Solve the system of equations without graphing. Explain or show your reasoning.
{2y=x−4
{4x+3y=5
Answer:
(2, -1)
Step-by-step explanation:
We can subtract x from both sides from the first equation, then multiply the first equation by 4, so it's easier to solve later:
-4x+8y = -16
4x+3y = 5
Then, we can add the 2 equations, so the x cancels out:
11y = -11
y=-1
Now, we can plug y as -1 to any of the equations above:
4x+3*(-1)=5
4x=8
x=2
Therefore, the solution to these 2 equations are (2, -1)
The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The system of equations is given below.
x = 2y + 4 ...1
4x + 3y = 5 ...2
From equations 1 and 2, then we have
4(2y + 4) + 3y = 5
8y + 16 + 3y = 5
11y = - 11
y = -1
Then the value of 'x' is given as,
x = 2 (-1) + 4
x = - 2 + 4
x = 2
The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.

What are the values of x and y if this equation is true?
22(x + yi) + (28 + 4i) 72 – 62i
Answer:
x = 2
y = -3
Step-by-step explanation:
The given equation is,
22(x + yi) + (28 + 4i) = 72 - 62i
By solving this equation further,
22x + 22yi + 28 + 4i = 72 - 62i
(22x + 28) + (22y + 4)i = 72 - 62i
Now both the sides of the equation is in the form of complex number,
By comparing real and imaginary parts given on both the sides,
22x + 28 = 72
22x = 72 - 28
22x = 44
x = 2
22y + 4 = -62
22y = -62 - 4
22y = -66
y = -3
Therefore, x = 2 and y = -3 are the values for which the given equation is true.
What is the value of x, rounded to one decimal place?
Answer:
x ≈ 5.9
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 2.7² = 6.5²
x² + 7.29 = 42.25 ( subtract 7.29 from both sides )
x² = 34.96 ( take the square root of both sides )
x = [tex]\sqrt{34.96}[/tex] ≈ 5.9 ( to 1 dec. place )

What do you mean by decimal fraction ?
A decimal fraction is a number in which the denominator is a multiple of 10 i.e., 10, 100, 1000. etc.
As per the question ;
The decimal number given is 0.00436.
To represent the number in the form of power of 10 , we need to move the decimal 3 places towards right.
and
We know if we move decimal 3 places towards right we need to multiply the resulted number by 10 to the power -3 , i.e., [tex]10^{-3}[/tex]
So,
The correct estimate will be ;
= 4.36 × [tex]10^{-3}[/tex]
Thus , the given estimate is not correct. The correct estimate will be 4.36 × [tex]10^{-3}[/tex].

Is it possible to have more than one (x,y)(x,y) pair that is a solution to both equations? Explain or show your reasoning
Here are the two equations:
Equation 1: 6x+4y=34
Equation 2: 5x-27=15
Answer with step-by-step explanation:
Yes, it is possible to have more that one (x,y) pair because of the distributive property.
6x + 4y = 34. If this is the case, we have to find 2 numbers that sum up to 34.
x = 3y = 45x - 27 = 15. If we are going to calculate this equation, you need to reverse the equation. 15 + 27 = 42 = 5x. If 42 = 5x, we have to divide 42 by 5, which is 8.4

The high school decided to buy new uniforms for the girls' and boys' basketball teams. They plan to buy 35 uniforms with a total cost of $1,235. The store offers discounts based on the number of items the school buys, as shown. What will the discounted price be for the high school?
Answer:
1049.75
Step-by-step explanation:
take 15% off of 1235 or 1235 divided by 15%
The discount will be 15% and the discounted price is $1049. 75
What is discount?A discount is a price reduction you offer a customer. There are also other methods that you can use to attract customers.
Given:
price for 35 uniforms = 1235
as, there is 15% discount for the items 25- 49 items.
So, there is 15% discount for 35 uniforms
Thus, the discounted price is
=1235 (1- 15%)
=1235 (1- 0.15)
=1235 x 0.85
= $1049. 75
Hence, the discounted price is $1049. 75.

The ratio between earths actual diameter and it’s scaled diameter can be used to find the scaled diameter of the other planets. Earths diameter of 12,756 kilometers is scaled to 3.5 centimeters as shown in the table. Now let’s find the scaled diameter of Mars as an example. Using the calculations shown, Mars diameter of 6,792 would be scaled to 1.9 centimeters. Use this same process to complete the table with the scaled diameters of the other planets.

What does it mean to be in proportion?If two given ratios are equal we say that the ratios are in proportion.
Example:
1/2 and 4/8 are in proportion.
- 1/2
- 4/8 = 1/2
We have,
Earths diameter = 12,756 km
It is scaled to 3.5 cm
The ratio is:
= 12,756 km /3.5 cm
Since each planet is in proportion with each planet.
We have,
Let the scaled diameter be d.
- Mercury d
12,756 / 3.5 = 4879 / d
d = (4879 x 3.5) / 12756
d = 1.3 cm
- Venus d
12,756 / 3.5 = 12104 / d
d = (12104 x 3.5) / 12756
d = 3.3 cm
- Jupiter d
12,756 / 3.5 = 142984 / d
d = (142984 x 3.5) / 12756
d = 39.2 cm
- Saturn d
12,756 / 3.5 = 120,536 / d
d = (120536. x3.5) / 12756
d = 33.1 cm
- Uranus d
12,756 / 3.5 = 51118 / d
d = (51118 x 3.5) / 12756
d = 14 cm
- Neptune d
12,756 / 3.5 = 49, 528 / d
d = (49528 x 3.5) / 12756
d = 13.6 cm
Thus the scaled diameter of each planet is:
Mercury - 1.3 cm
Venus - 3.3 cm
Jupiter - 39.2 cm
Saturn - 33.1 cm
Uranus - 14 cm
Neptune - 13.6 cm
