Answer:
Step-by-step explanation:
[tex]y =\frac{x+2}{x-4}\\\\y*(x-4)=x+2\\\\yx-4y = x+ 2\\\\yx-4y-x = 2\\\\yx -x = 2 +4y\\\\x(y-1)=2+4y\\\\x=\frac{2+4y}{y-1}[/tex]
Answer:
x = [tex]\frac{2+4y}{y-1}[/tex]
Step-by-step explanation:
Given
y = [tex]\frac{x+2}{x-4}[/tex] ( multiply both sides by x - 4 )
y(x - 4) = x + 2 ← distribute parenthesis on left side
xy - 4y = x + 2 ( add 4y to both sides )
xy = x + 2 + 4y ( subtract x from both sides )
xy - x = 2 + 4y ← factor out x from each term on the left side
x(y - 1) = 2 + 4y ( divide both sides by y - 1 )
x = [tex]\frac{2+4y}{y-1}[/tex]

in triangle PQR, m angle R = 32, p = 21, and q = 21. what is side lenth r? explain each step
Answer:
11.577 = r
Step-by-step explanation:
Comment
When you draw a sketch of this, <R is between p and q - - both of which are lines. The Cos law is the one you use.
Equation
r^2 = p^2 + q^2 - 2pq * Cos(R)
Givens
p = 21
q = 21
R = 32
r = ?
Solution
r^2 = 21^2 + 21^1 - 2*21*21 * Cos(32) Substitute givens into the equation
r^2 = 441 +441 - 882 * 0.8480 Add the first two terms.
r^2 = 882 - 747.98 Multiply Cos(32) by 2 * 21 * 21
r^2 = 134.02 Subtract 747.98 from 882
sqrt(r^2) = sqrt(134.02) Take the square root of both sides.
r = 11.577

hi so the problem is a recipe calls for a total of 3 2/3 cups of flour and sugar. If the recipe calls for 1/4 cup of sugar, how much flour is needed
1. 3 1/12
2. 3 1/4
3. 5/12
4. 3 11/12
Answer:
3 5/12 cups of flour are needed
Step-by-step explanation:
The flour-sugar total is 3 2/3 cups, of which 1/4 cup is sugar. So, to find the amount of flour used, we subtract 1/4 cup (sugar) from the total (3 2/3 cups):
11 1
----- - ---- where 11/3 is the improper fraction form of 3 2/3
3 4
The LCD is 12. Rewriting this subtraction using the LCD, we get:
44 3
---- - ----- = 41/12 (cups) = 3 5/12 cups
12 12
3 5/12 cups of flour are needed

The electricity to run a refrigerator for a week costs $6.30. How much does it cost to run the refrigerator for 365 days?
Answer: 327.60 dollars
Explanation:
There are about 52 weeks in a year (note that 365/7 = 52.14)
So that means it costs a total of 52*6.30 = 327.60 dollars to run the fridge for a full year.
Answer:
It costs $328.50 to run the refrigerator for 365 days
Step-by-step explanation:
Recall that there are seven days in a week and 52 weeks in a year
The given rate is
$6.30
-----------
7 days
To find the cost of running the refrigerator for 365 days, multiply this given rate by 365 days:
$6.30
----------- * 365 days = $328.50
7 days
It costs $328.50 to run the refrigerator for 365 days (1 year, 52 weeks).
the sum of 25 and x is 48 find x. . Solve.
Answer:
x = 23
Step-by-step explanation:
Sum of 25 and x = 48
25 + x = 48
Subtract 25 from both sides
25 - 25 cancels out
48 - 25 = 23
We would be left with x = 23
Answer:
[tex]x =23[/tex]
Step-by-step explanation:
Sum of 25 and x
[tex]25 + x[/tex]
Sum of 25 and x is 48
[tex]25 + x = 48[/tex]
Now lets simply Solve the equation
[tex]25 + x = 48 \\ x = 48 - 25 \\ x =23[/tex]

What is the answer for 2(n-1)+4n=2(3n-1)
Answer:
No solution
Step-by-step explanation:
2(n-1)+4n=2(3n-1)
2n-2+4n=6n-2
6n-2=6n-2
No solution
Answer:
0
Step-by-step explanation:
2(n-1)+4n=2(3n-1)
2n - 2 + 4n = 6n - 2
2n + 4n - 2 = 6n - 2
6n - 2 = 6n - 2

The equation of a linear function in point-slope form is y – y1 = m(x – x1). Harold correctly wrote the equation y = 3(x – 7) using a point and the slope. Which point did Harold use?
(7, 3)
(0, 7)
(7, 0)
(3, 7)
Answer:
The point is (7,0).
Step-by-step explanation:
The equation of a linear function in point-slope form is as follows :
[tex]y-y_1=m(x-x_1)[/tex] ...(1)
Where
(x₁,y₁) are the coordinates of the point which the line passes through it and (x,y).
Harold correctly wrote the equation y= 3(x–7)
or we can write it as :
y-0=3(x-7) ...(2)
Comparing equations (1) and (2), we get :
x₁ = 7 and y₁ = 0
So, the point is (7,0).
The correct option is (c).

The function h defined by h(t)=(49 + 4.9t)(10 - t) models the height, in meters, of an object t seconds after it is dropped from a helicopter.
Find or approximate the time when the object hits the ground. Explain your method.
The approximate time when the object hits the ground will be 10 seconds.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The function is given below.
h(t) = (49 + 4.9t)(10 - t)
The time when the object hits the ground is calculated as,
h(t) =
(49 + 4.9t)(10 - t) = 0
If (49 + 4.9t) = 0, then the value of 't' is given as,
49 + 4.9t = 0
t = - 10
The value of time is an absolute value. Thus, this can be neglected.
If (10 - t) = 0, then the value of 't' is given as,
10 - t = 0
t = 10 seconds
The approximate time when the object hits the ground will be 10 seconds.

A chef got 9 bags of onions. The red onions came in bags of 6 and the yellow onions came in bags of 7. If the chef got a total of 59 onions, how many bags of each type of onion did he get?
Answer:
yellow = 5 bags
red = 4 bags
Step-by-step explanation:
two equations can be derived from the question
x + y = 9 equation 1
6x + 7y = 59 equation 2
where x = number of red onion bags
y = number of yellow onion bags
Multiply equation 1 by 6
6x + 6y = 54 equation 3
subtract equation 3 from 2
y = 5
substitute for y in equation 1
x + 5 = 9
x = 9 - 5
x = 4
